Description copied from interface: ExtensionInfo

The name of the compiler for usage messages

Specified by:

compilerName in interface ExtensionInfo

defaultFileExtension

public abstract java.lang.String defaultFileExtension()

Description copied from interface: ExtensionInfo

The default extension that source files are expected to have.

Specified by:

defaultFileExtension in interface ExtensionInfo

version

public abstract Version version()

Description copied from interface: ExtensionInfo

Report the version of the extension.

Specified by:

version in interface ExtensionInfo

getOptions

public Options getOptions()

Description copied from interface: ExtensionInfo

getStats in interface ExtensionInfo

compiler

public Compiler compiler()

Specified by:

compiler in interface ExtensionInfo

initCompiler

public void initCompiler(Compiler compiler)

Description copied from interface: ExtensionInfo
