extract

public void extract(Builder builder)

Description copied from interface: ICoreFileReader

Used to extract OS-specific data. Called with a builder which is a sort of factory which will create the required implementation-specific data structures exist solely above the layer of this project.

Parameters:

builder -

getProcessorSubtype

public String getProcessorSubtype()

getCreationTime

public long getCreationTime()

getAdditionalFileNames

public Iterator getAdditionalFileNames()

Returns:

An iterator of String object specifying names of additional files needed by the Dump
