Method Detail

getType

public org.apache.bcel.generic.Type getType(org.apache.bcel.generic.ConstantPoolGen cp)

Specified by:

getType in interface org.apache.bcel.generic.TypedInstruction

Overrides:

getType in class org.apache.bcel.generic.ConversionInstruction

consumeStack

public int consumeStack(org.apache.bcel.generic.ConstantPoolGen cpg)

Specified by:

consumeStack in interface org.apache.bcel.generic.StackConsumer

Overrides:

consumeStack in class org.apache.bcel.generic.Instruction

produceStack

public int produceStack(org.apache.bcel.generic.ConstantPoolGen cpg)

Specified by:

produceStack in interface org.apache.bcel.generic.StackProducer

Overrides:

produceStack in class org.apache.bcel.generic.Instruction

hashCode

public int hashCode()

Overrides:

hashCode in class org.apache.bcel.generic.Instruction

accept

public void accept(org.apache.bcel.generic.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 org.apache.bcel.generic.Instruction

Parameters:

v - Visitor object
