Mongo::getSlave
(PECL mongo >=1.1.0)
Mongo::getSlave — Returns the address being used by this for slaveOkay reads
Beskrivelse
This finds the address of the slave currently being used for reads. It is a read-only method: it does not change anything about the internal state of the object.
When you create a connection to the database, the driver will not immediately
decide on a slave to use. Thus, after you connect, this function will return
NULL even if there are slaves available. When you first do a query with
slaveOkay set, at that point the driver will choose a slave for this
connection. At that point, this function will return the chosen slave.
See the query section of this manual for information on distributing reads to slaves.
Parametre
This function has no parameters.
Returnerings Værdier
The address of the slave this connection is using for reads.
This returns NULL if this is not connected to a replica set or not yet
initialized.
