    • Method Detail

      • values

        public static SourceVersion[] 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 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

      • latest

        public static SourceVersion latest()
        Returns the latest source version that can be modeled.
        Returns:
        the latest source version that can be modeled

      • latestSupported

        public static SourceVersion 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 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, 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 name)
        Returns whether or not name is a syntactically valid qualified name in the latest source version. Unlike isIdentifier, 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 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.
