Class BasicNIOConnPool

java.lang.Object

org.apache.http.nio.pool.AbstractNIOConnPool<HttpHost,NHttpClientConnection,BasicNIOPoolEntry>

org.apache.http.impl.nio.pool.BasicNIOConnPool

All Implemented Interfaces:

ConnPool<HttpHost,BasicNIOPoolEntry>, ConnPoolControl<HttpHost>

@ThreadSafe
public class BasicNIOConnPool
extends AbstractNIOConnPool<HttpHost,NHttpClientConnection,BasicNIOPoolEntry>

A very basic ConnPool implementation that represents a pool of non-blocking NHttpClientConnection connections identified by an HttpHost instance. Please note this pool implementation does not support complex routes via a proxy cannot differentiate between direct and proxied connections.

The following parameters can be used to customize the behavior of this class:

• CoreProtocolPNames.HTTP_ELEMENT_CHARSET
• CoreConnectionPNames.SO_TIMEOUT
• CoreConnectionPNames.CONNECTION_TIMEOUT
• CoreConnectionPNames.SOCKET_BUFFER_SIZE
• CoreConnectionPNames.MAX_HEADER_COUNT
• CoreConnectionPNames.MAX_LINE_LENGTH

Since:

4.2

Description copied from interface: ConnPool

Attempts to lease a connection for the given route and with the given state from the pool.

Specified by:

lease in interface ConnPool<HttpHost,BasicNIOPoolEntry>

Overrides:

lease in class AbstractNIOConnPool<HttpHost,NHttpClientConnection,BasicNIOPoolEntry>

Parameters:

route - route of the connection.

state - arbitrary object that represents a particular state (usually a security principal or a unique token identifying the user whose credentials have been used while establishing the connection). May be null.

callback - operation completion callback.

Returns:

future for a leased pool entry.

lease

public Future<BasicNIOPoolEntry> lease(HttpHost route,
                              Object state)

Overrides:
