Class Compiler.Output

java.lang.Object

com.ibm.wala.shrike.shrikeBT.Compiler.Output

Enclosing class:

Compiler

public static final class Compiler.Output
extends java.lang.Object

This class represents a method generated by a Compiler. One input method to the Compiler can generate multiple Outputs (if the input method is too big to be represented by a single method in the JVM, say if it requires more than 64K bytecodes).

Method Detail

getCode

public byte[] getCode()

Returns:

the actual bytecodes

getInstructionOffsets

public int[] getInstructionOffsets()

getMethodName

public java.lang.String getMethodName()

Returns:

the name of the method; either "null", if this code takes the place of the original method, or some string representing the name of a helper method

getMethodSignature

public java.lang.String getMethodSignature()

Returns:

the method signature in JVM format

getAccessFlags

public int getAccessFlags()

Returns:

the access flags that should be used for this method, or 0 if this is the code for the original method

getRawHandlers

public int[] getRawHandlers()

Returns:

the raw exception handler table in JVM format

isStatic

public boolean isStatic()

Returns:

whether the method is static

getNewBytecodesToOldBytecodes

public int[] getNewBytecodesToOldBytecodes()

Returns:

a map m such that the new bytecode instruction at offset i corresponds to the bytecode instruction at m[i] in the original method

getMaxStack

public int getMaxStack()

Returns:

the maximum stack size in words as required by the JVM

getMaxLocals

public int getMaxLocals()

Returns:

the maximum local variable size in words as required by the JVM
