1. 7.2 plugins/sources/list.inc \MigrateList::computeCount()

Implementors are expected to return a count of IDs available to be migrated.

Return value

int

3 methods override MigrateList::computeCount()

MigrateListFiles::computeCount in plugins/sources/files.inc

Return a count of all available IDs from the source listing.

MigrateListJSON::computeCount in plugins/sources/json.inc

Return a count of all available IDs from the source listing. The default implementation assumes the count of top-level elements reflects the number of IDs available - in many cases, you will need to override this to reflect your particular JSON structure.

MigrateListXML::computeCount in plugins/sources/xml.inc

Return a count of all available IDs from the source listing. The default implementation assumes the count of top-level elements reflects the number of IDs available - in many cases, you will need to override this to reflect your particular XML structure.

Support for migration from sources with distinct means of listing items to import and obtaining the items themselves.

Class

MigrateList

Extend the MigrateList class to provide a means to obtain a list of IDs to be migrated from a given source (e.g., MigrateListXML extends MigrateList to obtain a list of IDs from an XML document).
