com.mongodb.binding.AsyncClusterBinding

All Implemented Interfaces:

AsyncReadBinding, AsyncReadWriteBinding, AsyncWriteBinding, ReferenceCounted

public class AsyncClusterBinding
extends Object
implements AsyncReadWriteBinding

A simple ReadWriteBinding implementation that supplies write connection sources bound to a possibly different primary each time, and a read connection source bound to a possible different server each time.

Since:

3.0

Constructor Detail

AsyncClusterBinding

public AsyncClusterBinding(Cluster cluster,
                           ReadPreference readPreference)

Creates an instance.

Parameters:

cluster - a non-null Cluster which will be used to select a server to bind to

readPreference - a non-null ReadPreference for read operations

Method Detail

retain

public AsyncReadWriteBinding retain()

Description copied from interface: ReferenceCounted

Retain an additional reference to this object. All retained references must be released, or there will be a leak.

Specified by:

getReadPreference in interface AsyncReadBinding

Returns:

the non-null read preference

getSessionContext

public SessionContext getSessionContext()

Description copied from interface: AsyncReadBinding
