Abstract
A data processing method and apparatus are described for tracing paths through stored data structures defined by data objects coupled by identifying pointers and within a contiguous area of memory. A fixed sized marking stack or queue builds up a list of located objects as the structure or structures are traversed. The contiguous memory is divided into discrete pages with the linked data objects within each being considered in turn: any link to an object in another page causes an identifier for that page to be entered in a page list if one does not already exist, and a page table for each page identifies the location of the first and last identified objects within a page to set a range for subsequent scanning.
