Class DebugInfoDecoder

java.lang.Object

com.android.dx.dex.file.DebugInfoDecoder

public class DebugInfoDecoder
extends java.lang.Object

A decoder for the dex debug info state machine format. This code exists mostly as a reference implementation and test for for the DebugInfoEncoder

Method Summary

Modifier and Type	Method and Description
void	decode() Decodes the debug info sequence.
java.util.List<com.android.dx.dex.file.DebugInfoDecoder.LocalEntry>	getLocals() Gets the decoded locals list, in ascending start-address order.
java.util.List<com.android.dx.dex.file.DebugInfoDecoder.PositionEntry>	getPositionList() Gets the decoded positions list.
static void	validateEncode(byte[] info, DexFile file, CstMethodRef ref, DalvCode code, boolean isStatic) Validates an encoded debug info stream against data used to encode it, throwing an exception if they do not match.

validateEncode

public static void validateEncode(byte[] info,
                                  DexFile file,
                                  CstMethodRef ref,
                                  DalvCode code,
                                  boolean isStatic)

Validates an encoded debug info stream against data used to encode it, throwing an exception if they do not match. Used to validate the encoder.

Parameters:

info - encoded debug info

file - non-null; file to refer to during decoding

ref - non-null; method whose info is being decoded

code - non-null; original code object that was encoded

isStatic - whether the method is static
