Get IMethod from the method name in java

Question

I'm looking for a way to find the IMethod, given the method name as input for developing my eclipse plugin further.

Couldn't figure out a way to do so.

can someone please direct me in the right path.

There can be two approaches:

1. You can use the ASTVisitor pattern to visit the MethodDeclaration nodes, do a check for name and arguments, and get IMethod from them by resolving the binding. Refer the below posts:

   • Eclipse create CompilationUnit from .java file
   • How to convert AST to JDT Java model

2. Get the ITypes from the compilation unit and loop through the IMethods, do check for name and arguments to find the required one.

   IType [] typeDeclarationList = unit.getTypes();
   for (IType typeDeclaration : typeDeclarationList) {
      // Get methods under each type declaration.
      IMethod [] methodList = typeDeclaration.getMethods();
      for (IMethod method : methodList) {
         // Logic here.
      }
   }
