The DataFlavor representing a Java Image class, where:

     representationClass = java.awt.Image
     mimeType            = "image/x-java-image"
 

Will be null if java.awt.Image is not visible, the java.desktop module is not loaded, or the java.desktop module is not in the run-time image.

The DataFlavor representing plain text with Unicode encoding, where:

     representationClass = InputStream
     mimeType            = "text/plain; charset=unicode"
 

This DataFlavor has been deprecated because:

• Its representation is an InputStream, an 8-bit based representation, while Unicode is a 16-bit character set
• The charset "unicode" is not well-defined. "unicode" implies a particular platform's implementation of Unicode, not a cross-platform implementation

A MIME Content-Type of application/x-java-serialized-object represents a graph of Java object(s) that have been made persistent.

The representation class associated with this DataFlavor identifies the Java type of an object returned as a reference from an invocation java.awt.datatransfer.getTransferData.

To transfer a list of files to/from Java (and the underlying platform) a DataFlavor of this type/subtype and representation class of java.util.List is used. Each element of the list is required/guaranteed to be of type java.io.File.

To transfer a reference to an arbitrary Java object reference that has no associated MIME Content-type, across a Transferable interface WITHIN THE SAME JVM, a DataFlavor with this type/subtype is used, with a representationClass equal to the type of the class/interface being passed across the Transferable.

The object reference returned from Transferable.getTransferData for a DataFlavor with this MIME Content-Type is required to be an instance of the representation Class of the DataFlavor.

In order to pass a live link to a Remote object via a Drag and Drop ACTION_LINK operation a Mime Content Type of application/x-java-remote-object should be used, where the representation class of the DataFlavor represents the type of the Remote interface to be transferred.

Represents a piece of an HTML markup. The markup consists of the part selected on the source side. Therefore some tags in the markup may be unpaired. If the flavor is used to represent the data in a Transferable instance, no additional changes will be made. This DataFlavor instance represents the same HTML markup as DataFlavor instances which content MIME type does not contain document parameter and representation class is the String class.

     representationClass = String
     mimeType            = "text/html"
 

Represents a piece of an HTML markup. If possible, the markup received from a native system is supplemented with pair tags to be a well-formed HTML markup. If the flavor is used to represent the data in a Transferable instance, no additional changes will be made.

     representationClass = String
     mimeType            = "text/html"
 

Represents a piece of an HTML markup. If possible, the markup received from a native system is supplemented with additional tags to make up a well-formed HTML document. If the flavor is used to represent the data in a Transferable instance, no additional changes will be made.

     representationClass = String
     mimeType            = "text/html"
 

Constructs a DataFlavor that represents a Java class.

The returned DataFlavor will have the following characteristics:

    representationClass = representationClass
    mimeType            = application/x-java-serialized-object
 

Constructs a DataFlavor that represents a MimeType.

The returned DataFlavor will have the following characteristics:

If the mimeType is "application/x-java-serialized-object; class=<representation class>", the result is the same as calling new DataFlavor(Class.forName(<representation class>) .

Otherwise:

     representationClass = InputStream
     mimeType            = mimeType
 

Constructs a DataFlavor that represents a MimeType.

The returned DataFlavor will have the following characteristics:

If the mimeType is "application/x-java-serialized-object; class=<representation class>", the result is the same as calling new DataFlavor(Class.forName(<representation class>) .

Otherwise:

     representationClass = InputStream
     mimeType            = mimeType
 

Constructs a DataFlavor from a mimeType string. The string can specify a "class=<fully specified Java class name>" parameter to create a DataFlavor with the desired representation class. If the string does not contain "class=" parameter, java.io.InputStream is used as default.

String representation of this DataFlavor and its parameters. The resulting String contains the name of the DataFlavor class, this flavor's MIME type, and its representation class. If this flavor has a primary MIME type of "text", supports the charset parameter, and has an encoded representation, the flavor's charset is also included. See selectBestTextFlavor for a list of text flavors which support the charset parameter.

Returns a DataFlavor representing plain text with Unicode encoding, where:

     representationClass = java.io.InputStream
     mimeType            = "text/plain;
                            charset=<platform default Unicode encoding>"
 

Selects the best text DataFlavor from an array of DataFlavors. Only DataFlavor.stringFlavor, and equivalent flavors, and flavors that have a primary MIME type of "text", are considered for selection.

Flavors are first sorted by their MIME types in the following order:

• "text/sgml"
• "text/xml"
• "text/html"
• "text/rtf"
• "text/enriched"
• "text/richtext"
• "text/uri-list"
• "text/tab-separated-values"
• "text/t140"
• "text/rfc822-headers"
• "text/parityfec"
• "text/directory"
• "text/css"
• "text/calendar"
• "application/x-java-serialized-object"
• "text/plain"
• "text/<other>"

For example, "text/sgml" will be selected over "text/html", and DataFlavor.stringFlavor will be chosen over DataFlavor.plainTextFlavor.

If two or more flavors share the best MIME type in the array, then that MIME type will be checked to see if it supports the charset parameter.

The following MIME types support, or are treated as though they support, the charset parameter:

• "text/sgml"
• "text/xml"
• "text/html"
• "text/enriched"
• "text/richtext"
• "text/uri-list"
• "text/directory"
• "text/css"
• "text/calendar"
• "application/x-java-serialized-object"
• "text/plain"

The following MIME types do not support, or are treated as though they do not support, the charset parameter:

• "text/rtf"
• "text/tab-separated-values"
• "text/t140"
• "text/rfc822-headers"
• "text/parityfec"

For "text/<other>" MIME types, the first time the JRE needs to determine whether the MIME type supports the charset parameter, it will check whether the parameter is explicitly listed in an arbitrarily chosen DataFlavor which uses that MIME type. If so, the JRE will assume from that point on that the MIME type supports the charset parameter and will not check again. If the parameter is not explicitly listed, the JRE will assume from that point on that the MIME type does not support the charset parameter and will not check again. Because this check is performed on an arbitrarily chosen DataFlavor, developers must ensure that all DataFlavors with a "text/<other>" MIME type specify the charset parameter if it is supported by that MIME type. Developers should never rely on the JRE to substitute the platform's default charset for a "text/<other>" DataFlavor. Failure to adhere to this restriction will lead to undefined behavior.

If the best MIME type in the array does not support the charset parameter, the flavors which share that MIME type will then be sorted by their representation classes in the following order: java.io.InputStream, java.nio.ByteBuffer, [B, <all others>.

If two or more flavors share the best representation class, or if no flavor has one of the three specified representations, then one of those flavors will be chosen non-deterministically.

If the best MIME type in the array does support the charset parameter, the flavors which share that MIME type will then be sorted by their representation classes in the following order: java.io.Reader, java.lang.String, java.nio.CharBuffer, [C, <all others>.

If two or more flavors share the best representation class, and that representation is one of the four explicitly listed, then one of those flavors will be chosen non-deterministically. If, however, no flavor has one of the four specified representations, the flavors will then be sorted by their charsets. Unicode charsets, such as "UTF-16", "UTF-8", "UTF-16BE", "UTF-16LE", and their aliases, are considered best. After them, the platform default charset and its aliases are selected. "US-ASCII" and its aliases are worst. All other charsets are chosen in alphabetical order, but only charsets supported by this implementation of the Java platform will be considered.

If two or more flavors share the best charset, the flavors will then again be sorted by their representation classes in the following order: java.io.InputStream, java.nio.ByteBuffer, [B, <all others>.

If two or more flavors share the best representation class, or if no flavor has one of the three specified representations, then one of those flavors will be chosen non-deterministically.

Gets a Reader for a text flavor, decoded, if necessary, for the expected charset (encoding). The supported representation classes are java.io.Reader, java.lang.String, java.nio.CharBuffer, [C, java.io.InputStream, java.nio.ByteBuffer, and [B.

Because text flavors which do not support the charset parameter are encoded in a non-standard format, this method should not be called for such flavors. However, in order to maintain backward-compatibility, if this method is called for such a flavor, this method will treat the flavor as though it supports the charset parameter and attempt to decode it accordingly. See selectBestTextFlavor for a list of text flavors which do not support the charset parameter.

Returns the MIME type string for this DataFlavor.

Returns the Class which objects supporting this DataFlavor will return when this DataFlavor is requested.

Returns the human presentable name for the data format that this DataFlavor represents. This name would be localized for different countries.

Returns the primary MIME type for this DataFlavor.

Returns the sub MIME type of this DataFlavor.

Returns the human presentable name for this DataFlavor if paramName equals "humanPresentableName". Otherwise returns the MIME type value associated with paramName.

Sets the human presentable name for the data format that this DataFlavor represents. This name would be localized for different countries.

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

• It is reflexive: for any non-null reference value x, x.equals(x) should return true.
• It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
• It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
• It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
• For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes ; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

The equals comparison for the DataFlavor class is implemented as follows: Two DataFlavors are considered equal if and only if their MIME primary type and subtype and representation class are equal. Additionally, if the primary type is "text", the subtype denotes a text flavor which supports the charset parameter, and the representation class is not java.io.Reader, java.lang.String, java.nio.CharBuffer, or [C, the charset parameter must also be equal. If a charset is not explicitly specified for one or both DataFlavors, the platform default encoding is assumed. See selectBestTextFlavor for a list of text flavors which support the charset parameter.

This method has the same behavior as equals(Object). The only difference being that it takes a DataFlavor instance as a parameter.

Compares only the mimeType against the passed in String and representationClass is not considered in the comparison. If representationClass needs to be compared, then equals(new DataFlavor(s)) may be used.

Returns hash code for this DataFlavor. For two equal DataFlavors, hash codes are equal. For the String that matches DataFlavor.equals(String), it is not guaranteed that DataFlavor's hash code is equal to the hash code of the String.

Identical to equals(DataFlavor).

Returns whether the string representation of the MIME type passed in is equivalent to the MIME type of this DataFlavor. Parameters are not included in the comparison.

Returns true if the DataFlavor specified represents a serialized object.

Returns true if the DataFlavor specified represents a remote object.

Returns true if the DataFlavor specified represents a list of file objects.

Returns whether this DataFlavor is a valid text flavor for this implementation of the Java platform. Only flavors equivalent to DataFlavor.stringFlavor and DataFlavors with a primary MIME type of "text" can be valid text flavors.

If this flavor supports the charset parameter, it must be equivalent to DataFlavor.stringFlavor, or its representation must be java.io.Reader, java.lang.String, java.nio.CharBuffer, [C, java.io.InputStream, java.nio.ByteBuffer, or [B. If the representation is java.io.InputStream, java.nio.ByteBuffer, or [B, then this flavor's charset parameter must be supported by this implementation of the Java platform. If a charset is not specified, then the platform default charset, which is always supported, is assumed.

If this flavor does not support the charset parameter, its representation must be java.io.InputStream, java.nio.ByteBuffer, or [B.

See selectBestTextFlavor for a list of text flavors which support the charset parameter.

Serializes this DataFlavor.

Restores this DataFlavor from a Serialized state.

Returns a clone of this DataFlavor.

Called on DataFlavor for every MIME Type parameter to allow DataFlavor subclasses to handle special parameters like the text/plain charset parameters, whose values are case insensitive. (MIME type parameter values are supposed to be case sensitive.

This method is called for each parameter name/value pair and should return the normalized representation of the parameterValue.

Called for each MIME type string to give DataFlavor subtypes the opportunity to change how the normalization of MIME types is accomplished. One possible use would be to add default parameter/value pairs in cases where none are present in the MIME type string passed in.
