Class MethodAnalyzer

java.lang.Object

org.jf.dexlib2.analysis.MethodAnalyzer

public class MethodAnalyzer
extends java.lang.Object

The MethodAnalyzer performs several functions. It "analyzes" the instructions and infers the register types for each register, it can deodex odexed instructions, and it can verify the bytecode. The analysis and verification are done in two separate passes, because the analysis has to process instructions multiple times in some cases, and there's no need to perform the verification multiple times, so we wait until the method is fully analyzed and then verify it. Before calling the analyze() method, you must have initialized the ClassPath by calling ClassPath.InitializeClassPath
