Class SimpleLocalUses

java.lang.Object
  soot.toolkits.scalar.SimpleLocalUses

All Implemented Interfaces:

LocalUses

public class SimpleLocalUses
extends Object
implements LocalUses

Analysis that implements the LocalUses interface. Uses for a Local defined at a given Unit are returned as a list of UnitValueBoxPairs each containing a Unit that use the local and the Local itself wrapped in a ValueBox.

Constructor Summary

SimpleLocalUses(Body body, LocalDefs localDefs)
Construct the analysis from a method body and a LocalDefs interface.

SimpleLocalUses(UnitGraph graph, LocalDefs localDefs)
Construct the analysis from a UnitGraph representation of a method body and a LocalDefs interface.

Method Summary

List	getUsesOf(Unit s) Uses for a Local defined at a given Unit are returned as a list of UnitValueBoxPairs each containing a Unit that use the local and the Local itself wrapped in a ValueBox.

Constructor Detail

SimpleLocalUses

public SimpleLocalUses(UnitGraph graph,
                       LocalDefs localDefs)

Construct the analysis from a UnitGraph representation of a method body and a LocalDefs interface. This supposes that a LocalDefs analysis must have been computed prior.

Note: If you do not already have a UnitGraph, it may be cheaper to use the constructor which only requires a Body.

SimpleLocalUses

public SimpleLocalUses(Body body,
                       LocalDefs localDefs)

Construct the analysis from a method body and a LocalDefs interface. This supposes that a LocalDefs analysis must have been computed prior.

Method Detail

getUsesOf

public List getUsesOf(Unit s)

Uses for a Local defined at a given Unit are returned as a list of UnitValueBoxPairs each containing a Unit that use the local and the Local itself wrapped in a ValueBox.

Specified by:

getUsesOf in interface LocalUses

Parameters:

s - a unit that we want to query for the uses of the Local it (may) define.

Returns:

a UnitValueBoxPair of the Units that use the Local.
