Method Summary
void	acceptVisit(com.techtrader.modules.tools.bytecode.visitor.BCVisitor visit)           Accept a visit from a BCVisitor, calling the appropriate methods to notify the visitor that it has entered this entity, and to provide it with the proper callbacks for each sub-entity owned by this object.
private  void	calculateOpCode()
protected  void	copy(Instruction orig)
boolean	equals(java.lang.Object other)           Two return instructions are equal if the types they reference are equal or if either unset.
int	getStackChange()           Return the number of stack positions this instruction pushes or pops during its execution.
java.lang.Class	getType()           Get the type to return; this is one of: int, float, double, long, void, or Object.class.
java.lang.String	getTypeName()           Get the type to return; this is one of: int, float, double, long, void, or java.lang.Object.
ReturnInstruction	setType(java.lang.Class type)           Set the type to rturn; Object types other than Object.class will be demoted to Object.class, and primitives that have no direct support (boolean, char, short, byte) will be converted to int.class.
ReturnInstruction	setTypeName(java.lang.String name)           Set the type to load by name.

                            java.lang.Class type)

Method Detail

getType

public java.lang.Class getType()

Get the type to return; this is one of: int, float, double, long, void, or Object.class. If the type has not been set, this method will return null.

---

getTypeName

public java.lang.String getTypeName()

Get the type to return; this is one of: int, float, double, long, void, or java.lang.Object. If the type has not been set, this method will return null.

---

setType

public ReturnInstruction setType(java.lang.Class type)

Set the type to rturn; Object types other than Object.class will be demoted to Object.class, and primitives that have no direct support (boolean, char, short, byte) will be converted to int.class.

---

setTypeName

public ReturnInstruction setTypeName(java.lang.String name)

Set the type to load by name.

---

equals

public boolean equals(java.lang.Object other)

Two return instructions are equal if the types they reference are equal or if either unset.

Overrides:

equals in class Instruction

---

getStackChange

public int getStackChange()

Description copied from class: Instruction

Return the number of stack positions this instruction pushes or pops during its execution.

Overrides:

getStackChange in class Instruction

---

copy

protected void copy(Instruction orig)

Overrides:

copy in class Instruction

---

calculateOpCode

private void calculateOpCode()

---

acceptVisit

public void acceptVisit(com.techtrader.modules.tools.bytecode.visitor.BCVisitor visit)

Description copied from interface: com.techtrader.modules.tools.bytecode.visitor.VisitAcceptor

Accept a visit from a BCVisitor, calling the appropriate methods to notify the visitor that it has entered this entity, and to provide it with the proper callbacks for each sub-entity owned by this object.

Specified by:

acceptVisit in interface com.techtrader.modules.tools.bytecode.visitor.VisitAcceptor

Overrides:

acceptVisit in class Instruction
