INVOKEINTERFACE

public INVOKEINTERFACE(int index,
                       int nargs)

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

getCount

public int getCount()

The count argument according to the Java Language Specification, Second Edition.

toString

public java.lang.String toString(ConstantPool cp)

Overrides:

toString in class InvokeInstruction

Returns:

mnemonic for instruction with symbolic references resolved

consumeStack

public int consumeStack(ConstantPoolGen cpg)

Description copied from class: InvokeInstruction

Also works for instructions whose stack effect depends on the constant pool entry they reference.

Specified by:

consumeStack in interface StackConsumer

Overrides:

consumeStack in class InvokeInstruction

Returns:

Number of words consumed from stack by this instruction

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:

accept in class Instruction

Parameters:

v - Visitor object
