Method Detail
* #### values public static [SourceVersion](../../../javax/lang/model/SourceVersion.html "enum in javax.lang.model")[] values() Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows: for (SourceVersion c : SourceVersion.values()) System.out.println(c); Returns: an array containing the constants of this enum type, in the order they are declared * #### valueOf public static [SourceVersion](../../../javax/lang/model/SourceVersion.html "enum in javax.lang.model") valueOf([String](../../../java/lang/String.html "class in java.lang") 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](../../../java/lang/IllegalArgumentException.html "class in java.lang")` \- if this enum type has no constant with the specified name `[NullPointerException](../../../java/lang/NullPointerException.html "class in java.lang")` \- if the argument is null * #### latest public static [SourceVersion](../../../javax/lang/model/SourceVersion.html "enum in javax.lang.model") latest() Returns the latest source version that can be modeled. Returns: the latest source version that can be modeled * #### latestSupported public static [SourceVersion](../../../javax/lang/model/SourceVersion.html "enum in javax.lang.model") latestSupported() Returns the latest source version fully supported by the current execution environment. `RELEASE_5` or later must be returned. Returns: the latest source version that is fully supported * #### isIdentifier public static boolean isIdentifier([CharSequence](../../../java/lang/CharSequence.html "interface in java.lang") 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)](../../../java/lang/Character.html#isJavaIdentifierStart-int-) returns `true`, followed only by characters for which [Character.isJavaIdentifierPart(int)](../../../java/lang/Character.html#isJavaIdentifierPart-int-) returns `true`. This pattern matches regular identifiers, keywords, and the literals `"true"`, `"false"`, and `"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. * #### isName public static boolean isName([CharSequence](../../../java/lang/CharSequence.html "interface in java.lang") name) Returns whether or not `name` is a syntactically valid qualified name in the latest source version. Unlike [isIdentifier](../../../javax/lang/model/SourceVersion.html#isIdentifier-java.lang.CharSequence-), this method returns `false` for keywords and literals. Parameters: `name` \- the string to check Returns: `true` if this string is a syntactically valid name, `false` otherwise. See The Java™ Language Specification: 6.2 Names and Identifiers * #### isKeyword public static boolean isKeyword([CharSequence](../../../java/lang/CharSequence.html "interface in java.lang") s) Returns whether or not `s` is a keyword or literal in the latest source version. Parameters: `s` \- the string to check Returns: `true` if `s` is a keyword or literal, `false` otherwise.
