Members

Name	Modifiers	Type	Description	Overrides
MerciItemMigrateSource::getNextRow	public	function	Implementation of MigrateSource::getNextRow(). Overrides MigrateSourceSQL::getNextRow
MerciItemMigrateSource::__construct	public	function	Simple initialization. Overrides MigrateSourceSQL::__construct
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::$numIgnored	protected	property	Number of rows intentionally ignored (prepareRow() returned FALSE)
MigrateSource::$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
MigrateSourceSQL::$batch	protected	property	Current data batch.
MigrateSourceSQL::$batchSize	protected	property	Number of records to fetch from the database during each batch. A value of zero indicates no batching is to be done.
MigrateSourceSQL::$fields	protected	property	List of available source fields.
MigrateSourceSQL::$highwaterSeen	protected	property	Whether, in the current iteration, we have reached the highwater mark.
MigrateSourceSQL::$mapJoinable	protected	property	If the map is a MigrateSQLMap, and the table is compatible with the source query, we can join directly to the map and make things much faster and simpler.
MigrateSourceSQL::$numProcessed	protected	property	Number of eligible rows processed so far (used for itemlimit checking). Overrides MigrateSource::$numProcessed
MigrateSourceSQL::$originalQuery	protected	property	The SQL query objects from which to obtain data, and counts of data.
MigrateSourceSQL::$result	protected	property	The result object from executing the query - traversed to process the incoming data.
MigrateSourceSQL::$usingHighwater	protected	property	Whether this source is configured to use a highwater mark, and there is a highwater mark present to use.
MigrateSourceSQL::computeCount	public	function	Return a count of all available source records.
MigrateSourceSQL::fields	public	function	Returns a list of fields available to be mapped from the source query. Overrides MigrateSource::fields
MigrateSourceSQL::getNextBatch	protected	function	Downloads the next set of data from the source database.
MigrateSourceSQL::options	public static	function	Return an options array for PDO sources.
MigrateSourceSQL::performRewind	public	function	Implementation of MigrateSource::performRewind().
MigrateSourceSQL::query	public	function	Return a reference to the base query, in particular so Migration classes can add conditions/joins/etc to the query for a source defined in a base class.
MigrateSourceSQL::setMapJoinable	public	function
MigrateSourceSQL::__toString	public	function	Return a string representing the source query.
