UnknownTargetModel

public UnknownTargetModel(IClassHierarchy cha,
 AnalysisOptions options,
 IAnalysisCacheView cache,
 AndroidComponent target)

Parameters:

target - Component Type, may be null: No restrictions are imposed on AndroidModel then

Method Details

selectEntryPoint

protected boolean selectEntryPoint(AndroidEntryPoint ep)

The UnknownTargetModel does not call any entrypoints on it's own.

Instead it first creates a restricted AndroidModel and an ExternalModel. These are actually called.

Overrides:

selectEntryPoint in class AndroidModel

Parameters:

ep - The EntryPoint in question

Returns:

if the given EntryPoint shall be part of the model

getMethod

public SummarizedMethod getMethod()
                           throws CancelException

Description copied from class: AndroidModel

Building the SummarizedMethod is delayed upon the first class to this method.

Overrides:

getMethod in class AndroidModel

Returns:

the method for this model as generated by build()

Throws:

CancelException

build

protected void build(Atom name,
 Collection<? extends AndroidEntryPoint> entrypoints)
              throws CancelException

Description copied from class: AndroidModel

Generate the SummarizedMethod for the model (in this.model).

The actual generated model depends on the on the properties of this overloaded class. Most generated methods should reside in the AndroidModelClass and take AndroidComponents as well as some parameters (these marked REUSE) to the EntryPoints of the components.

Use AndroidModel.getMethod() to retrieve the method generated here or getMethodAs to get a version which is wrapped to another signature.

Overrides:

build in class AndroidModel

Parameters:

name - The name the generated method will be known as

entrypoints - The functions to call additionally to boot-code and XXX

Throws:

CancelException
