Class DefaultConnectionSpec

java.lang.Object

org.jredis.connector.ConnectionSpec.RefImpl

org.jredis.ri.alphazero.connection.DefaultConnectionSpec

All Implemented Interfaces:

ConnectionSpec

public final class DefaultConnectionSpec
extends ConnectionSpec.RefImpl

Default connection spec provides the following default values for a connection. See ConnectionSpec for details of these properties and flags.

The default Connection.Modality for the Connection is Connection.Modality.Synchronous.

This ConnectionSpec is configured to prefer bandwidth and relatively large (48K) buffers (which is probably less than your OS's default buffer sizes anyway, but you never know).

Connection Retry limit is DefaultConnectionSpec#DEFAULT_RECONNECT_CNT.

Connection is spec'd for Keep Alive.

Socket timeout is DEFAULT_READ_TIMEOUT_MSEC

No codecs and/or compression classes are defined.

alpha.0
