Class OpaqueMemory32

java.lang.Object

de.ibapl.jnhw.common.memory.AbstractNativeMemory

de.ibapl.jnhw.common.memory.OpaqueMemory32

All Implemented Interfaces:

Native

Direct Known Subclasses:

Memory32Heap, NativeIntNumber, NativeRunnable, PointerArray32, Struct32, StructArray32

public abstract class OpaqueMemory32
extends AbstractNativeMemory
implements Native

The base class for any chunk (i.e. pointer to or structs) of native memory. The run method in MemoryCleaner will clean up the allocated memory after finalizing this instance - if this instance owns the memory.
