Package com.pnfsoftware.jeb.core.units.code.java

package com.pnfsoftware.jeb.core.units.code.java

Types used to manipulate dexdec-generated (Dex decompiler) Java Abstract Syntax Tree (AST) objects. dexdec returns Java units built upon the interfaces defined in this package. Users can use this API to write custom AST optimizers, that will be run by dexdec in later phases of code decompilation. Interfaces and classes/enums in this package start with IJava... or J..., respectively.

dexdec AST optimizer plugins may be written in Python or Java.

A sample skeleton plugin, in Python:

 #?type=dexdec-ast
 from com.pnfsoftware.jeb.core.units.code.java import AbstractJOptimizer
 
 class JOptSamplePython(AbstractJOptimizer):
   def perform(self):
     return 0  # no optimization is performed
 

The same sample plugin, in Java:

 //?type=dexdec-ast
 import com.pnfsoftware.jeb.core.units.code.java.AbstractJOptimizer;
 
 public class JOptSampleJava extends AbstractJOptimizer {
     // note: implicit no-arg constructor is calling super()
     
     @Override
     public int perform() {
         // no optimization performed
         return 0;
     }
 }
