Class DexBody

java.lang.Object

soot.dexpler.DexBody

public class DexBody
extends java.lang.Object

A DexBody contains the code of a DexMethod and is used as a wrapper around JimpleBody in the jimplification process.

Add unit to this body.

Parameters:

u - Unit to add.

addDeferredJimplification

public void addDeferredJimplification(DeferableInstruction i)

Add a deferred instruction to this body.

Parameters:

i - the deferred instruction.

addRetype

getBody

public Body getBody()

Return the associated JimpleBody.

Throws:

java.lang.RuntimeException - if no jimplification happened yet.

getRegisterLocals

public Local[] getRegisterLocals()

Return the Locals that are associated with the current register state.

getRegisterLocal

public Local getRegisterLocal(int num)
                       throws InvalidDalvikBytecodeException

Return the Local that are associated with the number in the current register state. Handles if the register number actually points to a method parameter.

Parameters:

num - the register number

Throws:

InvalidDalvikBytecodeException

getStoreResultLocal

public Local getStoreResultLocal()

instructionAtAddress

public DexlibAbstractInstruction instructionAtAddress(int address)

Return the instruction that is present at the byte code address.

Parameters:

address - the byte code address.

Throws:
