Class SpecializedInstantiator
java.lang.Object
com.ibm.wala.dalvik.ipa.callgraph.androidModel.parameters.FlatInstantiator
com.ibm.wala.dalvik.ipa.callgraph.androidModel.parameters.SpecializedInstantiator
- All Implemented Interfaces:
IInstantiator
Instantiates certain android-types differently.
For example instantiating an android.content.Context would pull in all Android-components in scope resulting in a massivly overapproximated model.

createInstance
public SSAValue createInstance(TypeReference T, boolean asManaged, SSAValue.VariableKey key, Set<? extends SSAValue> seen) Creates a new instance of type calling all that's necessary.If T is a class-type all its constructors are searched for the one found best suited (takes the least arguments, ...). New instances are created for all parameters, then the constructor is called.
If T represents multiple types (is an interface, abstract class, ...) _all_ implementors of that type are instantiated After that they get Phi-ed together.
If T is an array-type a new array of length 1 is generated.
