Only connections currently owned by the connection manager are processed. See Also:   HttpConnection.isOpen since:    3.0 getConnection public HttpConnection getConnection(HostConfiguration hostConfiguration)(Code) See Also:   HttpConnectionManager.getConnection(HostConfiguration) getConnection public HttpConnection getConnection(HostConfiguration hostConfiguration, long timeout) throws HttpException(Code) See Also:   HttpConnectionManager.getConnection(HostConfigurationlong) getConnectionWithTimeout public HttpConnection getConnectionWithTimeout(HostConfiguration hostConfiguration, long timeout) throws ConnectionPoolTimeoutException(Code) Gets a connection or waits if one is not available. A connection is available if one exists that is not being used or if fewer than maxHostConnections have been created in the connectionPool, and fewer than maxTotalConnections have been created in all connectionPools. Parameters:   hostConfiguration - The host configuration specifying the connectiondetails. Parameters:   timeout - the number of milliseconds to wait for a connection, 0 towait indefinitely HttpConnection an available connection throws:   HttpException - if a connection does not become available in'timeout' milliseconds since:    3.0 getConnectionsInPool public int getConnectionsInPool(HostConfiguration hostConfiguration)(Code) Gets the total number of pooled connections for the given host configuration. This is the total number of connections that have been created and are still in use by this connection manager for the host configuration. This value will not exceed the MultiThreadedHttpConnectionManager.getMaxConnectionsPerHost() maximum number of connections perhost . Parameters:   hostConfiguration - The host configuration The total number of pooled connections getConnectionsInPool public int getConnectionsInPool()(Code) Gets the total number of pooled connections. This is the total number of connections that have been created and are still in use by this connection manager. This value will not exceed the MultiThreadedHttpConnectionManager.getMaxTotalConnections() maximum number of connections . the total number of pooled connections getConnectionsInUse public int getConnectionsInUse(HostConfiguration hostConfiguration)(Code) Gets the number of connections in use for this configuration. Parameters:   hostConfiguration - the key that connections are tracked on the number of connections in useMultiThreadedHttpConnectionManager.getConnectionsInPool(HostConfiguration) getConnectionsInUse public int getConnectionsInUse()(Code) Gets the total number of connections in use. the total number of connections in useMultiThreadedHttpConnectionManager.getConnectionsInPool() getMaxConnectionsPerHost public int getMaxConnectionsPerHost()(Code) Gets the maximum number of connections allowed for a given hostConfiguration. The maximum number of connections allowed for a givenhostConfiguration.HttpConnectionManagerParams.getDefaultMaxConnectionsPerHostHttpConnectionManager.getParams getMaxTotalConnections public int getMaxTotalConnections()(Code) Gets the maximum number of connections allowed for this connection manager. The maximum number of connections allowedHttpConnectionManagerParams.getMaxTotalConnectionsHttpConnectionManager.getParams getParams public HttpConnectionManagerParams getParams()(Code) Returns HttpConnectionManagerParams parameters associated with this connection manager. since:    3.0 See Also:   HttpConnectionManagerParams isConnectionStaleCheckingEnabled public boolean isConnectionStaleCheckingEnabled()(Code) Gets the staleCheckingEnabled value to be set on HttpConnections that are created. true if stale checking will be enabled on HttpConnections See Also:   HttpConnection.isStaleCheckingEnabledHttpConnectionManagerParams.isStaleCheckingEnabledHttpConnectionManager.getParams releaseConnection public void releaseConnection(HttpConnection conn)(Code) Make the given HttpConnection available for use by other requests. If another thread is blocked in getConnection() that could use this connection, it will be woken up. Parameters:   conn - the HttpConnection to make available. setConnectionStaleCheckingEnabled public void setConnectionStaleCheckingEnabled(boolean connectionStaleCheckingEnabled)(Code) Sets the staleCheckingEnabled value to be set on HttpConnections that are created. Parameters:   connectionStaleCheckingEnabled - true if stale checking will be enabled on HttpConnections See Also:   HttpConnection.setStaleCheckingEnabled(boolean)HttpConnectionManagerParams.setStaleCheckingEnabled(boolean)HttpConnectionManager.getParams setMaxConnectionsPerHost public void setMaxConnectionsPerHost(int maxHostConnections)(Code) Sets the maximum number of connections allowed for a given HostConfiguration. Per RFC 2616 section 8.1.4, this value defaults to 2. Parameters:   maxHostConnections - the number of connections allowed for eachhostConfigurationHttpConnectionManagerParams.setDefaultMaxConnectionsPerHost(int)HttpConnectionManager.getParams setMaxTotalConnections public void setMaxTotalConnections(int maxTotalConnections)(Code) Sets the maximum number of connections allowed for this connection manager. Parameters:   maxTotalConnections - the maximum number of connections allowedHttpConnectionManagerParams.setMaxTotalConnections(int)HttpConnectionManager.getParams setParams public void setParams(HttpConnectionManagerParams params)(Code) Assigns HttpConnectionManagerParams parameters for this connection manager. since:    3.0 See Also:   HttpConnectionManagerParams shutdown public synchronized void shutdown()(Code) Shuts down the connection manager and releases all resources. All connections associated with this class will be closed and released. The connection manager can no longer be used once shut down. Calling this method more than once will have no effect. shutdownAll public static void shutdownAll()(Code) Shuts down and cleans up resources used by all instances of MultiThreadedHttpConnectionManager. All static resources are released, all threads are stopped, and MultiThreadedHttpConnectionManager.shutdown() is called on all live instances of MultiThreadedHttpConnectionManager.
