isIdentifier	back to summary
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, contextual keywords, boolean literals, and the null literal. The method returns `false` for all other strings. Parameters name:CharSequence the string to check Returns:boolean `true` if this string is a syntactically valid identifier or keyword, `false` otherwise. Java Language Specification 3.8 Identifiers

This pattern matches regular identifiers, keywords, contextual keywords, boolean literals, and the null literal. The method returns false for all other strings.

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 contextual keywords. Parameters name:CharSequence the string to check Returns:boolean `true` if this string is a syntactically valid name, `false` otherwise.

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 contextual keywords.

latestSupported	back to summary
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 from 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:SourceVersion the latest source version fully supported by the current execution environment

valueOf	back to summary
public static SourceVersion valueOf(Runtime.Version rv) Returns the latest source version that is usable under the runtime version argument. If the runtime version's feature is greater than the feature of the runtime version of the latest source version, an `IllegalArgumentException` is thrown. Because the source versions of the Java programming language have so far followed a linear progression, only the feature component of a runtime version is queried to determine the mapping to a source version. If that linearity changes in the future, other components of the runtime version may influence the result. API Note An expression to convert from a string value, for example `"17"`, to the corresponding source version, `RELEASE_17`, is: `SourceVersion.valueOf(Runtime.Version.parse("17"))` SourceVersion.valueOf(Runtime.Version.parse("17")) Parameters rv:Runtime.Version runtime version to map to a source version Returns:SourceVersion the latest source version that is usable under the runtime version argument Exceptions IllegalArgumentException: if the feature of version argument is greater than the feature of the platform version.

If that linearity changes in the future, other components of the runtime version may influence the result.
