How to get count and types of method parameters using org.objectweb.asm.MethodVisitor?

QUESTION

How to get count and types of method parameters using org.objectweb.asm.MethodVisitor?

Asked 2021-Jun-14 at 07:55

I'm trying to extract method parameters information from Java class bytecode using asm MethodVisitor. visitParameter method of MethodVisitor is not called (because no parameter names are present in compiled class file). How can i get count of method parameters and their types?

The only thing I've found so far is desc parameter of visitMethod from MethodVisitor. I can copy-paste TraceSignatureVisitor class from asm-util, rewrite about 50 lines of code to store parameters declarations into List/array instead of single StringBuffer.

Another option is suggested by in answer "https://stackoverflow.com/questions/18061588/get-function-arguments-values-using-java-asm-for-bytecode-instrimentation":

The number of arguments to the method can be computed from the method description using the code in the following gist: https://gist.github.com/VijayKrishna/6160036. Using the parseMethodArguments(String desc) method you can easily compute the number of arguments to the method.

From my point of view copy-pasting and rewriting TraceSignatureVisitor is still better.

But i suppose there should be more simple way to work with method signatures in asm-util. Is there?

ASM has an abstract for that purpose, Type.

Instances of Type may represent a primitive type, a reference type, or a method type. So you can first get a type to represent the method type from the descriptor string, followed by querying it for the parameter types and return type.
