Mongo::getSlave

(PECL mongo >=1.1.0)

Mongo::getSlave — Returns the address being used by this for slaveOkay reads

Описание

public string Mongo::getSlave ( void )

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.
