Examples of org.eclipse.jdt.core.dom.ASTParser.createAST()

org.eclipse.jdt.core.dom.ASTParser.createAST()
Creates an abstract syntax tree.
A successful call to this method returns all settings to their default values so the object is ready to be reused.
@param monitor the progress monitor used to report progress and request cancellation,or null if none @return an AST node whose type depends on the kind of parserequested, with a fallback to a CompilationUnit in the case of severe parsing errors @exception IllegalStateException if the settings providedare insufficient, contradictory, or otherwise unsupported
