Members

Name	Modifiers	Type	Description	Overrides
MigrateSource::$activeMap	protected	property	The MigrateMap class for the current migration.
MigrateSource::$activeMigration	protected	property	The Migration class currently invoking us, during rewind() and next().
MigrateSource::$cacheCounts	protected	property	Whether this instance should cache the source count.
MigrateSource::$cacheKey	protected	property	Key to use for caching counts.
MigrateSource::$currentKey	protected	property	The primary key of the current row
MigrateSource::$currentRow	protected	property	The current row from the quey
MigrateSource::$highwaterField	protected	property	Information on the highwater mark for the current migration, if any.
MigrateSource::$idList	protected	property	List of source IDs to process.
MigrateSource::$mapRowAdded	protected	property	By default, next() will directly read the map row and add it to the data row. A source plugin implementation may do this itself (in particular, the SQL source can incorporate the map table into the query) - if so, it should set this TRUE so we…
MigrateSource::$multikeySeparator	protected	property	Used in the case of multiple key sources that need to use idlist.
MigrateSource::$numIgnored	protected	property	Number of rows intentionally ignored (prepareRow() returned FALSE)
MigrateSource::$numProcessed	protected	property	Number of rows we've at least looked at.	1
MigrateSource::$originalHighwater	protected	property	The highwater mark at the beginning of the import operation.
MigrateSource::$skipCount	protected	property	Whether this instance should not attempt to count the source.
MigrateSource::$trackChanges	protected	property	If TRUE, we will maintain hashed source rows to determine whether incoming data has changed.
MigrateSource::count	public	function	Return a count of available source records, from the cache if appropriate. Returns -1 if the source is not countable.
MigrateSource::current	public	function	Implementation of Iterator::current() - called when entering a loop iteration, returning the current row
MigrateSource::dataChanged	protected	function	Determine whether this row has changed, and therefore whether it should be processed.
MigrateSource::getCurrentKey	public	function
MigrateSource::getIgnored	public	function
MigrateSource::getProcessed	public	function
MigrateSource::hash	protected	function	Generate a hash of the source row.	3
MigrateSource::key	public	function	Implementation of Iterator::key - called when entering a loop iteration, returning the key of the current row. It must be a scalar - we will serialize to fulfill the requirement, but using getCurrentKey() is preferable.
MigrateSource::next	public	function	Implementation of Iterator::next() - subclasses of MigrateSource should implement getNextRow() to retrieve the next valid source rocord to process.
MigrateSource::prepareRow	protected	function	Give the calling migration a shot at manipulating, and possibly rejecting, the source row.
MigrateSource::resetStats	public	function	Reset numIgnored back to 0.
MigrateSource::rewind	public	function	Implementation of Iterator::rewind() - subclasses of MigrateSource should implement performRewind() to do any class-specific setup for iterating source records.
MigrateSource::valid	public	function	Implementation of Iterator::valid() - called at the top of the loop, returning TRUE to process the loop and FALSE to terminate it
MigrateSourceEntityReference::getNextRow	public	function	Fetch the next row of data, returning it as an object. Return FALSE when there is no more data available.
MigrateSourceEntityReference::__construct		function	Constructor. Overrides MigrateSourceReference::__construct
MigrateSourceReference::$fields	protected	property	Machine names of fields that will be imported.
MigrateSourceReference::$field_type	protected	property	Field type.
MigrateSourceReference::$next_row	protected	property	ID of a row, that will be imported during next iteration.
MigrateSourceReference::$result	protected	property	Place where data is stored during import.
MigrateSourceReference::computeCount	public	function	Return the number of available source records.
MigrateSourceReference::fields	public	function	Returns a list of fields available to be mapped from the source, keyed by field name. Overrides MigrateSource::fields
MigrateSourceReference::performRewind	public	function	Do whatever needs to be done to start a fresh traversal of the source data.
MigrateSourceReference::_constructRow	protected	function	Constructs row object, that should be returned from $this->getNextRow().
MigrateSourceReference::__toString	public	function	Return a string representing the source, for display in the UI.
