Constructor Detail

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

getNoArguments

public int getNoArguments()

Deprecated. Use getCount().

The Java Virtual Machine Specification, First Edition was a little bit unprecise about the naming. In the Java Virtual Machine Specification, Second Edition, the value returned here is called "count".

getCount

public int getCount()

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

initFromFile

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

Read needed data (i.e., index) from file.

Overrides:

initFromFile in class CPInstruction

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

Parameters:

bytes - input stream

wide - wide prefix?

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.

Overrides:

consumeStack in class InvokeInstruction

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

Overrides:

accept in class Instruction

Parameters:

v - Visitor object
