Detailed Description

BranchHandle is returned by specialized InstructionList.append() whenever a BranchInstruction is appended. This is useful when the target of this instruction is not known at time of creation and must be set later via setTarget().

Member Function Documentation

void BranchHandle::addHandle (    )  [inline, protected]

Handle adds itself to the list of resuable handles. Reimplemented from InstructionHandle. Definition at line 28 of file src/de/fub/bytecode/generic/BranchHandle.java.

void BranchHandle::addHandle (    )  [inline, protected]

Handle adds itself to the list of resuable handles. Reimplemented from InstructionHandle. Definition at line 28 of file lib/jpf/de/fub/bytecode/generic/BranchHandle.java.

InstructionHandle BranchHandle::getTarget (    )  [inline]

Returns: target of instruction. Definition at line 52 of file src/de/fub/bytecode/generic/BranchHandle.java.

InstructionHandle BranchHandle::getTarget (    )  [inline]

Returns: target of instruction. Definition at line 54 of file lib/jpf/de/fub/bytecode/generic/BranchHandle.java.

void BranchHandle::setInstruction (  Instruction   i )  [inline]

Set new contents. Old instruction is disposed and may not be used anymore. Reimplemented from InstructionHandle. Definition at line 58 of file src/de/fub/bytecode/generic/BranchHandle.java.

void BranchHandle::setInstruction (  Instruction   i )  [inline]

Set new contents. Old instruction is disposed and may not be used anymore. Reimplemented from InstructionHandle. Definition at line 60 of file lib/jpf/de/fub/bytecode/generic/BranchHandle.java.

void BranchHandle::setTarget (  InstructionHandle   ih )  [inline]

Pass new target to instruction. Definition at line 73 of file src/de/fub/bytecode/generic/BranchHandle.java.

void BranchHandle::setTarget (  InstructionHandle   ih )  [inline]

Pass new target to instruction. Definition at line 77 of file lib/jpf/de/fub/bytecode/generic/BranchHandle.java.

int BranchHandle::updatePosition (  int   offset, int   max_offset )  [inline, protected]

Called by InstructionList.setPositions when setting the position for every instruction. In the presence of variable length instructions `setPositions' performs multiple passes over the instruction list to calculate the correct (byte) positions and offsets by calling this function. Parameters: offset   additional offset caused by preceding (variable length) instructions max_offset   the maximum offset that may be caused by these instructions Returns: additional offset caused by possible change of this instruction's length Reimplemented from InstructionHandle. Definition at line 76 of file src/de/fub/bytecode/generic/BranchHandle.java.

int BranchHandle::updatePosition (  int   offset, int   max_offset )  [inline, protected]

Called by InstructionList.setPositions when setting the position for every instruction. In the presence of variable length instructions `setPositions' performs multiple passes over the instruction list to calculate the correct (byte) positions and offsets by calling this function. Parameters: offset   additional offset caused by preceding (variable length) instructions max_offset   the maximum offset that may be caused by these instructions Returns: additional offset caused by possible change of this instruction's length Reimplemented from InstructionHandle. Definition at line 80 of file lib/jpf/de/fub/bytecode/generic/BranchHandle.java.

void BranchHandle::updateTarget (  InstructionHandle   old_ih, InstructionHandle   new_ih )  [inline]

Update target of instruction. Definition at line 84 of file src/de/fub/bytecode/generic/BranchHandle.java.

void BranchHandle::updateTarget (  InstructionHandle   old_ih, InstructionHandle   new_ih )  [inline]

Update target of instruction. Definition at line 88 of file lib/jpf/de/fub/bytecode/generic/BranchHandle.java.
