Method Detail

getBehavior

public IInstantiationBehavior.InstanceBehavior getBehavior(com.ibm.wala.types.TypeName type,
                                                  com.ibm.wala.types.TypeName asParameterTo,
                                                  com.ibm.wala.types.MethodReference inCall,
                                                  String withName)

Returns how the model should behave on the type. See the documentation of IInstantiationBehavior.InstanceBehavior for the description of the possible behaviours. Although this function takes a parameter withName one should not rely on its value.

Specified by:

getBehavior in class IInstantiationBehavior

Parameters:

asParameterTo - not considered

inCall - not considered

withName - not considered

type - The type of the variable in question

Returns:

The behaviour to use

getExactness

public IInstantiationBehavior.Exactness getExactness(com.ibm.wala.types.TypeName type,
                                            com.ibm.wala.types.TypeName asParameterTo,
                                            com.ibm.wala.types.MethodReference inCall,
                                            String withName)

The Exactness depends on how the behavior to a type was determined. Currently it has no effect on the model but it may come in handy if you want to cascade classes for determining the IInstanciationBehavior. The DefaultInstanciationBehavior only knows EXACT, PACKAGE, PREFIX and DEFAULT

Specified by:

getExactness in class IInstantiationBehavior

getDafultBehavior

public IInstantiationBehavior.InstanceBehavior getDafultBehavior()

Specified by:

getDafultBehavior in class IInstantiationBehavior

Returns:

InstanceBehavior.REUSE

type2atom

protected static com.ibm.wala.util.strings.Atom type2atom(com.ibm.wala.types.TypeName type)

Convert a TypeName back to an Atom.
