Method Detail

createParser

public static IShallowParser createParser(ELanguage language)
                                   throws ShallowParserException

Returns a new parser for the given language.

While we call this method "create" for consistency with other factories, the parsers are actually created only once and then cached for reuse. The reason is that parser creation may be expensive, especially when many very small code fragments are to be parsed. Reusing parsers is possible as the parsers do not hold state of a specific parse and even can be used concurrently in multiple threads.

Throws:

ShallowParserException - if the language is not (yet) supported by our framework.

supportsLanguage

public static boolean supportsLanguage(ELanguage language)

Returns whether the given language is supported by the parser factory.

getSupportedLanguages

public static java.util.EnumSet<ELanguage> getSupportedLanguages()

Returns all ELanguages for which we have shallow parsers.
