class:DosFileAttributeView [NONE]
  • All Superinterfaces:
    AttributeView, BasicFileAttributeView, FileAttributeView 
    public interface DosFileAttributeView
extends BasicFileAttributeView
    A file attribute view that provides a view of the legacy "DOS" file attributes. These attributes are supported by file systems such as the File Allocation Table (FAT) format commonly used in consumer devices .

    A DosFileAttributeView is a BasicFileAttributeView that additionally supports access to the set of DOS attribute flags that are used to indicate if the file is read-only, hidden, a system file, or archived.

    Where dynamic access to file attributes is required, the attributes supported by this attribute view are as defined by BasicFileAttributeView , and in addition, the following attributes are supported:

    Supported attributes
    Name Type
    readonly Boolean
    hidden Boolean
    system Boolean
    archive Boolean

    The getAttribute method may be used to read any of these attributes, or any of the attributes defined by BasicFileAttributeView as if by invoking the readAttributes() method.

    The setAttribute method may be used to update the file's last modified time, last access time or create time attributes as defined by BasicFileAttributeView. It may also be used to update the DOS attributes as if by invoking the setReadOnly, setHidden, setSystem, and setArchive methods respectively.

    Since:
    1.7

method:name() [NONE]

  • name

    String name()
    Returns the name of the attribute view. Attribute views of this type have the name "dos".
    Specified by:
    name in interface AttributeView
    Specified by:
    name in interface BasicFileAttributeView
    Returns:
    the name of the attribute view

method:readAttributes() [NONE]

method:setReadOnly(boolean) [NONE]

  • setReadOnly

    void setReadOnly​(boolean value)
          throws IOException
    Updates the value of the read-only attribute.

    It is implementation specific if the attribute can be updated as an atomic operation with respect to other file system operations. An implementation may, for example, require to read the existing value of the DOS attribute in order to update this attribute.

    Parameters:
    value - the new value of the attribute
    Throws:
    IOException - if an I/O error occurs
    SecurityException - In the case of the default, and a security manager is installed, its checkWrite method is invoked to check write access to the file

method:setHidden(boolean) [NONE]

  • setHidden

    void setHidden​(boolean value)
        throws IOException
    Updates the value of the hidden attribute.

    It is implementation specific if the attribute can be updated as an atomic operation with respect to other file system operations. An implementation may, for example, require to read the existing value of the DOS attribute in order to update this attribute.

    Parameters:
    value - the new value of the attribute
    Throws:
    IOException - if an I/O error occurs
    SecurityException - In the case of the default, and a security manager is installed, its checkWrite method is invoked to check write access to the file

method:setSystem(boolean) [NONE]

  • setSystem

    void setSystem​(boolean value)
        throws IOException
    Updates the value of the system attribute.

    It is implementation specific if the attribute can be updated as an atomic operation with respect to other file system operations. An implementation may, for example, require to read the existing value of the DOS attribute in order to update this attribute.

    Parameters:
    value - the new value of the attribute
    Throws:
    IOException - if an I/O error occurs
    SecurityException - In the case of the default, and a security manager is installed, its checkWrite method is invoked to check write access to the file

method:setArchive(boolean) [NONE]

  • setArchive

    void setArchive​(boolean value)
         throws IOException
    Updates the value of the archive attribute.

    It is implementation specific if the attribute can be updated as an atomic operation with respect to other file system operations. An implementation may, for example, require to read the existing value of the DOS attribute in order to update this attribute.

    Parameters:
    value - the new value of the attribute
    Throws:
    IOException - if an I/O error occurs
    SecurityException - In the case of the default, and a security manager is installed, its checkWrite method is invoked to check write access to the file
