Constructor Detail

TABLESWITCH

public TABLESWITCH(int[] match,
                   InstructionHandle[] targets,
                   InstructionHandle target)

Parameters:

match - sorted array of match values, match[0] must be low value, match[match_length - 1] high value

targets - where to branch for matched values

target - default branch

Method Detail

dump

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

Dump instruction as byte code to stream out.

Overrides:

dump in class Select

Parameters:

out - Output stream

initFromFile

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

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

Overrides:

initFromFile in class Select

Following copied from class: de.fub.bytecode.generic.BranchInstruction

Parameters:

bytes - input stream

wide - wide prefix?

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.

Overrides:

accept in class Instruction

Parameters:

v - Visitor object
