Class ParameterAccessor.Parameter

java.lang.Object

com.ibm.wala.core.util.ssa.SSAValue

com.ibm.wala.core.util.ssa.ParameterAccessor.Parameter

Direct Known Subclasses:

ReuseParameters.ReuseParameter

Enclosing class:

ParameterAccessor

public static class ParameterAccessor.Parameter
extends SSAValue

The representation of a Parameter handled using a ParameterAccessor.

It basically consists of a SSA-Value and an associated TypeReference.

Use .getNumber() to access the associated SSA-Value.

Parameter

protected Parameter(int number,
 String name,
 TypeReference type,
 ParameterAccessor.ParameterDisposition disp,
 ParameterAccessor.BasedOn basedOn,
 MethodReference mRef,
 int descriptorOffset)

Create Parameters using ParameterAccessor.

Parameters:

number - SSA-Value to access this parameter

name - Optional variable-name - may be null

type - Variable Type to this parameter

disp - Implicit this, regular parameter or return value?

basedOn - Is Accessor constructed with IMethod or MethodReference

mRef - Method this parameter belongs to

descriptorOffset - add to number to get position in descriptor

Method Details

getNumberInDescriptor

public int getNumberInDescriptor()

The position of the parameter in the methods Descriptor starting with 1.

getDisposition

public ParameterAccessor.ParameterDisposition getDisposition()

equals

public boolean equals(Object o)

Overrides:

equals in class SSAValue

Throws:

IllegalArgumentException - if you compare this to an object totally different.

hashCode

public final int hashCode()

Clashes deliberately with SSAValue as it's basically the same thing.

Overrides:

hashCode in class SSAValue

toString

public String toString()

Overrides:

toString in class SSAValue
