Class ASMCreatorParameterNameResolver

java.lang.Object

com.owlike.genson.reflect.ASMCreatorParameterNameResolver

All Implemented Interfaces:

PropertyNameResolver

public final class ASMCreatorParameterNameResolver
extends Object
implements PropertyNameResolver

This class uses ASM library to resolve method and constructor parameter names from debug symbols generated during compilation. Most libraries are compiled with debug symbols so in most cases this class will be able to resolve them. It's pretty cool as you do not need to annotate the parameters anymore! However be careful if you decide to use this feature, you must ensure that your software is compiled with debug symbols for production! That's why this feature is disabled by default. To enable it :

 new Genson.Builder().setWithDebugInfoPropertyNameResolver(true).create();
 

If you enabled this feature, when a class with no debug symbols is encountered no exception will be thrown, if you want you can force exceptions with

 new Genson.Builder().setWithDebugInfoPropertyNameResolver(true)
                .setThrowExceptionIfNoDebugInfo(true).create();
