Examples of SWT AST manipulation

1.use Eclipse internal AST methods to get the source code of a java file.groovy

def inputJavaElement = eclipse.editors.compilationUnits().first().getInputJavaElement()
def compilationUnit = inputJavaElement.getCompilationUnit();
def type = compilationUnit.getTypes()[0];
def method = type.getMethods()[0];
//inspect(method)
return method.source;

2. helper methods to get AST data from Java file in editor.groovy

def javaCompilationUnit = eclipse.editors.javaCompilationUnit("TeamMentorAPI.java");
//def compilationUnit = javaCompilationUnit.compilationUnit();
//inspect(compilationUnit)

def types = javaCompilationUnit.types();
def methods = javaCompilationUnit.methods();
def methodNames = javaCompilationUnit.method_Names();
def method = javaCompilationUnit.method("open_Article");
def source = javaCompilationUnit.method_Source("open_Article");
return source
