Interface ImageAddressSpace

All Known Implementing Classes:

ImageAddressSpace, J9DDRImageAddressSpace, JCImageAddressSpace

public interface ImageAddressSpace

Represents a single address space within the image.

On some operating systems (e.g. z/OS), there can be more than one address space per core file and more than one process per address space.

Method Summary

Modifier and Type	Method	Description
ByteOrder	getByteOrder()	Return the byte order of this address space.
ImageProcess	getCurrentProcess()	Get the process within this address space that caused the image to be created.
String	getID()	Gets the system wide identifier for the address space
Iterator	getImageSections()	Get the raw memory in the address space.
ImagePointer	getPointer(long address)	A factory method for creating pointers into this address space.
Iterator	getProcesses()	Get the set of processes within the address space.
Properties	getProperties()	Gets the OS specific properties for this address space.

Method Details

getCurrentProcess

ImageProcess getCurrentProcess()

Get the process within this address space that caused the image to be created.

Returns:

the process within this address space which caused the image to be created, if any. Return null if no individual process triggered the creation of the image.

getProcesses

Iterator getProcesses()

Get the set of processes within the address space.

Returns:

an iterator which provides all of the processes within a given address space.

getByteOrder

ByteOrder getByteOrder()

Return the byte order of this address space.

Returns:

the byte order of this address space

getPointer

ImagePointer getPointer(long address)

A factory method for creating pointers into this address space.

Parameters:

address - the address to point to.

Returns:

an ImagePointer for the specified address.

getImageSections

Iterator getImageSections()

Get the raw memory in the address space.

Returns:

An iterator of all the ImageSections in the address. Their union will be the total process address space.
