Passing through the AST node

Question

I want to find out the line number the call refers to using the AST api in the package. How can i do this?

Answer 1

You have an illustration on how to search in the CompilationUnit method in this papercut article :

for (ICompilationUnit unit : mypackage.getCompilationUnits()) {
IType[] types = unit.getTypes();
for (int i = 0; i < types.length; i++) {
  IType type = types[i];
  IMethod[] methods = type.getMethods();

• If the method is ASTNode , you can use the function ASTNode.getStartPosition().
• If the compilation unit of this IMember is CompilationUnit, you can use it inCompilationUnit.getLineNumber(position)

Answer 2

CompilationUnit.getLineNumber (int position)

in relation to the CompilationUnit object
