proguard.optimize.gson.GsonDeserializationInvocationFinder

All Implemented Interfaces:

proguard.classfile.instruction.visitor.InstructionVisitor

public class GsonDeserializationInvocationFinder
extends java.lang.Object
implements proguard.classfile.instruction.visitor.InstructionVisitor

This instruction visitor searches the code for invocations to any of the deserialization methods of Gson (all the fromJson variants) and keeps track of the domain classes that are involved in the deserialization.

Parameters:

programClassPool - the program class pool used to look up class references.

libraryClassPool - the library class pool used to look up class references.

domainClassVisitor - the visitor to which found domain classes that are involved in Gson deserialization will be delegated.
