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 CPInstruction

Parameters:

out - Output stream

Throws:

java.io.IOException

getExceptions

public java.lang.Class<?>[] getExceptions()

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:
