Class AbstractClientConnAdapter

  • All Implemented Interfaces:
    java.io.Closeable, java.lang.AutoCloseable, ConnectionReleaseTrigger, HttpRoutedConnection, ManagedClientConnection, ManagedHttpClientConnection, org.apache.http.HttpClientConnection, org.apache.http.HttpConnection, org.apache.http.HttpInetConnection, org.apache.http.protocol.HttpContext
    Direct Known Subclasses:
    AbstractPooledConnAdapter
    @Deprecated
public abstract class AbstractClientConnAdapter
extends java.lang.Object
implements ManagedClientConnection, org.apache.http.protocol.HttpContext
    Deprecated.
    (4.2) do not use
    Abstract adapter from operated to managed client connections. Read and write methods are delegated to the wrapped connection. Operations affecting the connection state have to be implemented by derived classes. Operations for querying the connection state are delegated to the wrapped connection if there is one, or return a default value if there is none.

    This adapter tracks the checkpoints for reusable communication states, as indicated by markReusable and queried by isMarkedReusable. All send and receive operations will automatically clear the mark.

    Connection release calls are delegated to the connection manager, if there is one. abortConnection will clear the reusability mark first. The connection manager is expected to tolerate multiple calls to the release method.

    Since:
    4.0

      • isSecure

        public boolean isSecure()
        Deprecated.
        Description copied from interface: ManagedClientConnection
        Indicates whether this connection is secure. The return value is well-defined only while the connection is open. It may change even while the connection is open.
        Specified by:
        isSecure in interface HttpRoutedConnection
        Specified by:
        isSecure in interface ManagedClientConnection
        Returns:

      • bind

        public void bind​(java.net.Socket socket)
          throws java.io.IOException
        Deprecated.
        Description copied from interface: ManagedHttpClientConnection
        Binds this connection to the given socket. The connection is considered open if it is bound and the underlying socket is connection to a remote host.
        Specified by:
        bind in interface ManagedHttpClientConnection
        Parameters:
        socket - the socket to bind the connection to.
        Throws:
        java.io.IOException

      • getSSLSession

        public javax.net.ssl.SSLSession getSSLSession()
        Deprecated.
        Description copied from interface: ManagedClientConnection
        Obtains the SSL session of the underlying connection, if any. If this connection is open, and the underlying socket is an SSLSocket, the SSL session of that socket is obtained. This is a potentially blocking operation.

        Note: Whether the underlying socket is an SSL socket can not necessarily be determined via ManagedClientConnection.isSecure(). Plain sockets may be considered secure, for example if they are connected to a known host in the same network segment. On the other hand, SSL sockets may be considered insecure, for example depending on the chosen cipher suite.

        Specified by:
        getSSLSession in interface HttpRoutedConnection
        Specified by:
        getSSLSession in interface ManagedClientConnection
        Specified by:
        getSSLSession in interface ManagedHttpClientConnection
        Returns:
        the underlying SSL session if available, null otherwise

      • markReusable

        public void markReusable()
        Deprecated.
        Description copied from interface: ManagedClientConnection
        Marks this connection as being in a reusable communication state. The checkpoints for reuseable communication states (in the absence of pipelining) are before sending a request and after receiving the response in its entirety. The connection will automatically clear the checkpoint when used for communication. A call to this method indicates that the next checkpoint has been reached.

        A reusable communication state is necessary but not sufficient for the connection to be reused. A route mismatch, the connection being closed, or other circumstances might prevent reuse.

        Specified by:
        markReusable in interface ManagedClientConnection

      • unmarkReusable

        public void unmarkReusable()
        Deprecated.
        Description copied from interface: ManagedClientConnection
        Marks this connection as not being in a reusable state. This can be used immediately before releasing this connection to prevent its reuse. Reasons for preventing reuse include error conditions and the evaluation of a reuse strategy.

        Note: It is not necessary to call here before writing to or reading from this connection. Communication attempts will automatically unmark the state as non-reusable. It can then be switched back using markReusable.

        Specified by:
        unmarkReusable in interface ManagedClientConnection

      • setIdleDuration

        public void setIdleDuration​(long duration,
                            java.util.concurrent.TimeUnit unit)
        Deprecated.
        Description copied from interface: ManagedClientConnection
        Sets the duration that this connection can remain idle before it is reused. The connection should not be used again if this time elapses. The idle duration must be reset after each request sent over this connection. The elapsed time starts counting when the connection is released, which is typically after the headers (and any response body, if present) is fully consumed.
        Specified by:
        setIdleDuration in interface ManagedClientConnection

      • releaseConnection

        public void releaseConnection()
        Deprecated.
        Description copied from interface: ConnectionReleaseTrigger
        Releases the connection with the option of keep-alive. This is a "graceful" release and may cause IO operations for consuming the remainder of a response entity. Use abortConnection for a hard release. The connection may be reused as specified by the duration.
        Specified by:
        releaseConnection in interface ConnectionReleaseTrigger
