Constructor Detail

InvokeInstruction

InvokeInstruction()

Empty constructor needed for the Class.newInstance() statement in Instruction.readInstruction(). Not to be used otherwise.

---

InvokeInstruction

protected InvokeInstruction(short opcode,
                            int index)

Method Detail

toString

public java.lang.String toString(org.apache.bcel.classfile.ConstantPool cp)

Overrides:

toString in class CPInstruction

---

consumeStack

public int consumeStack(ConstantPoolGen cpg)

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 Instruction

---

produceStack

public int produceStack(ConstantPoolGen cpg)

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

Specified by:

produceStack in interface StackProducer

Overrides:

produceStack in class Instruction

---

getType

public Type getType(ConstantPoolGen cpg)

Description copied from interface: LoadClass

Returns the type associated with this instruction. LoadClass instances are always typed, but this type does not always refer to the type of the class or interface that it possibly forces to load. For example, GETFIELD would return the type of the field and not the type of the class where the field is defined. If no class is forced to be loaded, null is returned. An example for this is an ANEWARRAY instruction that creates an int[][].

Specified by:

getType in interface TypedInstruction

Overrides:

getType in class CPInstruction

---

getMethodName

public java.lang.String getMethodName(ConstantPoolGen cpg)

---

getReturnType

public Type getReturnType(ConstantPoolGen cpg)

---

getArgumentTypes

public Type[] getArgumentTypes(ConstantPoolGen cpg)

---
