method:values() [NONE]

values

public static SourceVersion[] values()

Returns an array containing the constants of this enum type, in the order they are declared.

Returns:: an array containing the constants of this enum type, in the order they are declared

method:valueOf(java.lang.String) [NONE]

valueOf

public static SourceVersion valueOf?(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:: name - the name of the enum constant to be returned.
Returns:: the enum constant with the specified name
Throws:: IllegalArgumentException - if this enum type has no constant with the specified name; NullPointerException - if the argument is null

method:latest() [NONE]

latest

public static SourceVersion latest()

Returns the latest source version that can be modeled.

Returns:: the latest source version that can be modeled

method:latestSupported() [NONE]

latestSupported

public static SourceVersion latestSupported()

Returns the latest source version fully supported by the current execution environment. RELEASE_9 or later must be returned.

API Note:: This method is included alongside latest() to allow identification of situations where the language model API is running on a platform version different than the latest version modeled by the API. One way that sort of situation can occur is if an IDE or similar tool is using the API to model source version N while running on platform version (N - 1). Running in this configuration is supported by the API. Running an API on platform versions earlier than (N - 1) or later than N may or may not work as an implementation detail. If an annotation processor was generating code to run under the current execution environment, the processor should only use platform features up to the latestSupported release, which may be earlier than the latest release.
Returns:: the latest source version that is fully supported

method:isIdentifier(java.lang.CharSequence) [NONE]

isIdentifier

public static boolean isIdentifier?(CharSequence name)

Returns whether or not name is a syntactically valid identifier (simple name) or keyword in the latest source version. The method returns true if the name consists of an initial character for which Character.isJavaIdentifierStart(int) returns true, followed only by characters for which Character.isJavaIdentifierPart(int) returns true. This pattern matches regular identifiers, keywords, restricted keywords, restricted identifiers and the literals "true", "false", "null". The method returns false for all other strings.

Parameters:: name - the string to check
Returns:: true if this string is a syntactically valid identifier or keyword, false otherwise.

method:isName(java.lang.CharSequence) [CHANGED]

isName

public static boolean isName?(CharSequence name)

Returns whether or not name is a syntactically valid qualified name in the latest source version. Syntactically, a qualified name is a sequence of identifiers separated by period characters ("."). This method splits the input string into period-separated segments and applies checks to each segment in turn. Unlike isIdentifier, this method returns false for keywords, boolean literals, and the null literal in any segment. This method returns true for restricted keywords and restricted identifiers .

Parameters:: name - the string to check
Returns:: true if this string is a syntactically valid name, false otherwise.
