Constructor Detail

GOTO_W

GOTO_W()

Empty constructor needed for Instruction.readInstruction. Not to be used otherwise.

GOTO_W

public GOTO_W(InstructionHandle target)

Constructs a GOTO_W instruction.

Parameters:

target - the target instruction.

Method Detail

accept

public void accept(Visitor v)

Call corresponding visitor method(s). The order is: Call visitor methods of implemented interfaces first, then call methods according to the class hierarchy in descending order, that is, the most specific visitXXX() call comes last.

Specified by:

accept in class Instruction

Parameters:

v - Visitor object.

dump

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

Dumps instruction as byte code to stream out.

Overrides:

dump in class BranchInstruction

Parameters:

out - Output stream.

Throws:

java.io.IOException - Thrown when an I/O exception of some sort has occurred.

initFromFile

protected void initFromFile(ByteSequence bytes,
                            boolean wide)
                     throws java.io.IOException

Reads needed data (for example index) from file.

Overrides:

initFromFile in class BranchInstruction

Parameters:

bytes - input stream.

wide - wide prefix?

Throws:

java.io.IOException - may be thrown if the implementation needs to read data from the file
