Class PooledConnectionProviderImpl<W,R>

java.lang.Object

io.reactivex.netty.client.pool.PooledConnectionProvider<W,R>

io.reactivex.netty.client.pool.PooledConnectionProviderImpl<W,R>

Type Parameters:

W - Type of object that is written to the client using this factory.

R - Type of object that is read from the the client using this factory.

All Implemented Interfaces:

ConnectionProvider<W,R>, PooledConnection.Owner

public final class PooledConnectionProviderImpl<W,R>
extends PooledConnectionProvider<W,R>

An implementation of PooledConnectionProvider that pools connections. Following are the key parameters:

• PoolLimitDeterminationStrategy: A strategy to determine whether a new physical connection should be created as part of the user request.
• PoolConfig.getIdleConnectionsCleanupTimer(): The schedule for cleaning up idle connections in the pool.
• PoolConfig.getMaxIdleTimeMillis(): Maximum time a connection can be idle in this pool.

PooledConnectionProviderImpl

public PooledConnectionProviderImpl(PoolConfig<W,R> poolConfig,
                                    HostConnector<W,R> hostConnector)

Method Detail

newConnectionRequest

public rx.Observable<Connection<R,W>> newConnectionRequest()

Description copied from interface: ConnectionProvider

Returns an Observable that emits a single connection every time it is subscribed.

Returns:

An Observable that emits a single connection every time it is subscribed.

release

public rx.Observable<java.lang.Void> release(PooledConnection<?,?> connection)

Description copied from interface: PooledConnection.Owner

Releases the passed connection back to the owner, for reuse.

Parameters:

connection - Connection to be released.

Returns:

Observable representing result of the release. Every subscription to this, releases the connection.

discard

public rx.Observable<java.lang.Void> discard(PooledConnection<?,?> connection)

Description copied from interface: PooledConnection.Owner

Discards the passed connection from the pool. This is usually called due to an external event like closing of a connection that the pool may not know.
This operation is idempotent and hence can be called multiple times with no side effects

Parameters:

connection - The connection to discard.

Returns:

Observable indicating the result of the discard (which usually results in a close()). Every subscription to this Observable will discard the connection.
