  org.mmtk.vm.Factory

Direct Known Subclasses:

Factory

public abstract class Factory
extends Object

This class defines factory methods for VM-specific types which must be instantiated within MMTk. Since the concrete type is defined at build time, we leave it to a concrete vm-specific instance of this class to perform the object instantiation.
