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