Method Detail

getAstRoot

public Node getAstRoot(AbstractCompiler compiler)

Description copied from interface: SourceAst

Gets the root node of the AST for the source file this represents. The AST is lazily instantiated and cached.

Specified by:: getAstRoot in interface SourceAst

clearAst

public void clearAst()

Description copied from interface: SourceAst

Removes any references to root node of the AST. If it is requested again, another parse will be performed. This method is needed to allow the ASTs to be garbage collected if the inputs are still around after compilation.

Specified by:: clearAst in interface SourceAst

getInputId

public InputId getInputId()

Specified by:: getInputId in interface SourceAst

Returns:: The input id associated with this AST

getSourceFile

public SourceFile getSourceFile()

Description copied from interface: SourceAst

Returns the source file the generated AST represents.

Specified by:: getSourceFile in interface SourceAst

setSourceFile

public void setSourceFile(SourceFile file)

Description copied from interface: SourceAst

Sets the source file the generated AST represents. This can be called after deserializing if access to the source file is needed. If a different file is provided than that with which this was created, an IllegalStateException will be thrown.
