public JSR_W(InstructionHandle target)

Method Details

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, i.e., the most specific visitXXX() call comes last.

Specified by:

accept in class Instruction

Parameters:

v - Visitor object

dump

public void dump(DataOutputStream out)
          throws IOException

Dump instruction as byte code to stream out.

Overrides:

dump in class BranchInstruction

Parameters:

out - Output stream

Throws:

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

initFromFile

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

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

Overrides:

initFromFile in class BranchInstruction

Parameters:

bytes - input stream

wide - wide prefix?

Throws:

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