protected int[] match

---

indices

protected int[] indices

---

targets

protected java.util.ArrayList targets

---

fixed_length

protected int fixed_length

---

match_length

protected int match_length

---

padding

protected int padding

Constructor Detail

Bytecodes.Select

Bytecodes.Select()

Empty constructor needed for the Class.newInstance() statement in Instruction.readInstruction(). Not to be used otherwise.

---

Bytecodes.Select

Bytecodes.Select(short opcode,
                 int[] match,
                 java.util.ArrayList targets,
                 Bytecodes.InstructionHandle target)

(Match, target) pairs for switch. `Match' and `targets' must have the same length of course.

Method Detail

updatePosition

protected int updatePosition(int offset,
                             int max_offset)

Since this is a variable length instruction, it may shift the following instructions which then need to update their position. 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.

Overrides:

updatePosition in class Bytecodes.BranchInstruction

---

dump

public void dump(java.io.DataOutputStream out)
          throws java.io.IOException

Dump instruction as byte code to stream out.

Overrides:

dump in class Bytecodes.BranchInstruction

---

initFromFile

protected void initFromFile(Clazz.jq_ConstantPool cp,
                            Util.IO.ByteSequence bytes,
                            boolean wide)
                     throws java.io.IOException

Read needed data (e.g. index) from file.

Overrides:

initFromFile in class Bytecodes.BranchInstruction

---

toString

public java.lang.String toString(boolean verbose)

Description copied from class: Bytecodes.BranchInstruction

Long output format: <position in byte code> <name of opcode> "["<opcode number>"]" "("<length of instruction>")" "<"<target instruction>">" "@"<branch target offset>

Overrides:

toString in class Bytecodes.BranchInstruction

---

setTarget

public void setTarget(int i,
                      Bytecodes.InstructionHandle target)

Set branch target for `i'th case

---

updateTarget

public void updateTarget(Bytecodes.InstructionHandle old_ih,
                         Bytecodes.InstructionHandle new_ih)

Specified by:

updateTarget in interface Bytecodes.InstructionTargeter

Overrides:

updateTarget in class Bytecodes.BranchInstruction

---

containsTarget

public boolean containsTarget(Bytecodes.InstructionHandle ih)

Specified by:

containsTarget in interface Bytecodes.InstructionTargeter

Overrides:

containsTarget in class Bytecodes.BranchInstruction

---

dispose

void dispose()

Inform targets that they're not targeted anymore.

Overrides:

dispose in class Bytecodes.BranchInstruction

---

public int[] getMatchs()

---

getIndices

public int[] getIndices()

---

getTargets

public java.util.List getTargets()
