Modifier and TypeMethod and Description
public void
accept(final Visitor
Visitor object
v
)

Implements abstract org.apache.bcel.generic.Instruction.accept.

Call corresponding visitor method(s).
public int
consumeStack(final ConstantPoolGen cpg)

Overrides org.apache.bcel.generic.InvokeInstruction.consumeStack.

Implements org.apache.bcel.generic.StackConsumer.consumeStack.

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

Method Detail

acceptback to summary
public void accept(final Visitor v)

Implements abstract org.apache.bcel.generic.Instruction.accept.

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.

Parameters
v:Visitor

Visitor object
