Class CollectExecutor

java.lang.Object

ghidra.pcode.exec.PcodeExecutor<MaskedBytes>

ghidra.pcode.emu.jit.decode.CollectExecutor

All Implemented Interfaces:

CanDecode

public class CollectExecutor
extends PcodeExecutor<MaskedBytes>
implements CanDecode

An executor that simply records the ops that would be executed

This decodes instructions by delegating to another given executor
