Package com.ibm.j9ddr.corereaders.memory

Class ProcessAddressSpace

java.lang.Object

com.ibm.j9ddr.corereaders.memory.SearchableMemory

com.ibm.j9ddr.corereaders.memory.AbstractMemory

com.ibm.j9ddr.corereaders.memory.ProcessAddressSpace

All Implemented Interfaces:

IAddressSpace, IMemory, IProcess

Direct Known Subclasses:

LinuxProcessAddressSpace, OSXProcessAddressSpace, WindowsProcessAddressSpace

public abstract class ProcessAddressSpace
extends AbstractMemory
implements IProcess, IAddressSpace

Object representing the single address space / process model used by Linux, AIX and Windows. The same object represents the process and the address space - which saves creating objects that exist solely to delegate.

Method Details

bytesPerPointer

public int bytesPerPointer()

Specified by:

bytesPerPointer in interface IProcess

Returns:

Number of bytes in a pointer

getPointerAt

public long getPointerAt(long address)
                  throws MemoryFault

Specified by:

getPointerAt in interface IProcess

Throws:

MemoryFault

getAddressSpaceId

public int getAddressSpaceId()

Specified by:

getAddressSpaceId in interface IAddressSpace
