Method Detail

addMappingback to summary
public boolean addMapping(String cTypeName, Class<? extends T> clazz)

Adds a mapping from the given C++ type name to the given Java class. The latter must be a subclass of sun.jvm.hotspot.runtime.VMObject. Returns false if there was already a class for this type name in the map.

instantiateWrapperForback to summary
public T instantiateWrapperFor(Address addr) throws WrongTypeException

Implements abstract sun.jvm.hotspot.runtime.InstanceConstructor.instantiateWrapperFor.

Instantiate the most-precisely typed wrapper object available for the type of the given Address. If no type in the mapping matched the type of the Address, throws a WrongTypeException. Returns null for a null address (similar behavior to VMObjectFactory).
