Class MiniModel

java.lang.Object

com.ibm.wala.dalvik.ipa.callgraph.androidModel.AndroidModel

com.ibm.wala.dalvik.ipa.callgraph.androidModel.MiniModel

All Implemented Interfaces:

com.ibm.wala.ipa.cha.IClassHierarchyDweller

public class MiniModel
extends AndroidModel

Models all classes derived from the given AndroidComponent.

So for example it contains all EntryPoints from all Activities.

It is like a "regular" AndroidModel but the calls are restricted to EntryPoints whose target-class is of the type of the given AndroidComponent.

In the ClassHierarchy a MiniModel will be known as "AndroidModelClass.???Model" (where ??? is the AndroidComponent) and be called by "AndroidModelClass.startUnknown???" (which is generated by the UnknownTargetModel).

A MiniModel is used when a startComponent-call (startActivity, bindService, ...) is encountered, but the Context at the call site is insufficient to determine the actual target. In this case an UnknownTargetModel which uses an MiniModel and an ExternalModel is placed there.

Method Detail

selectEntryPoint

protected boolean selectEntryPoint(AndroidEntryPoint ep)

Restrict the model to Activities.

Overridden by models to restraint Entrypoints.

For each entrypoint this method is queried if it should be part of the model.

Overrides:

selectEntryPoint in class AndroidModel

Parameters:

ep - The EntryPoint in question

Returns:

if the given EntryPoint shall be part of the model

getDescriptor
