Subroutine

Interface Subroutine

public interface Subroutine

This interface defines properties of JVM bytecode subroutines. Note that it is 'abused' to maintain the top-level code in a consistent fashion, too.

Method Summary
boolean	contains(InstructionHandle inst) Returns if the given InstructionHandle refers to an instruction that is part of this subroutine.
int[]	getAccessedLocalsIndices() Returns an int[] containing the indices of the local variable slots accessed by this Subroutine (read-accessed, write-accessed or both); local variables referenced by subroutines of this subroutine are not included.
InstructionHandle[]	getEnteringJsrInstructions() Returns all the JsrInstructions that have the first instruction of this subroutine as their target.
InstructionHandle[]	getInstructions() Returns all instructions that together form this subroutine.
InstructionHandle	getLeavingRET() Returns the one and only RET that leaves the subroutine.
int[]	getRecursivelyAccessedLocalsIndices() Returns an int[] containing the indices of the local variable slots accessed by this Subroutine (read-accessed, write-accessed or both); local variables referenced by subroutines of this subroutine are included.
Subroutine[]	subSubs() Returns the subroutines that are directly called from this subroutine.

Method Summary

boolean

contains(InstructionHandle inst)

Returns if the given InstructionHandle refers to an instruction that is part of this subroutine.

int[]

getAccessedLocalsIndices()

Returns an int[] containing the indices of the local variable slots accessed by this Subroutine (read-accessed, write-accessed or both); local variables referenced by subroutines of this subroutine are not included.

InstructionHandle[]

getEnteringJsrInstructions()

Returns all the JsrInstructions that have the first instruction of this subroutine as their target.

InstructionHandle[]

getInstructions()

Returns all instructions that together form this subroutine.

InstructionHandle

getLeavingRET()

Returns the one and only RET that leaves the subroutine.

int[]

getRecursivelyAccessedLocalsIndices()

Subroutine[]

subSubs()

Returns the subroutines that are directly called from this subroutine.

Method Detail

contains

Returns if the given InstructionHandle refers to an instruction that is part of this subroutine. This is a convenience method that saves iteration over the InstructionHandle objects returned by getInstructions().
