Method Details

getByteOrder

public ByteOrder getByteOrder()

Description copied from interface: ImageAddressSpace

Return the byte order of this address space.

Specified by:

getByteOrder in interface ImageAddressSpace

Returns:

the byte order of this address space

getCurrentProcess

public ImageProcess getCurrentProcess()

At the moment, just the last process to be added

Specified by:

getCurrentProcess in interface ImageAddressSpace

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.

getImageSections

public Iterator getImageSections()

Description copied from interface: ImageAddressSpace

Get the raw memory in the address space.

Specified by:

getImageSections in interface ImageAddressSpace

Returns:

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

getPointer

public ImagePointer getPointer(long address)

Description copied from interface: ImageAddressSpace

A factory method for creating pointers into this address space.

Specified by:

getPointer in interface ImageAddressSpace

Parameters:

address - the address to point to.

Returns:

an ImagePointer for the specified address.
