  • Method Details

    • preCreateConnections

      public CompletableFuture<Void> preCreateConnections(int connectionCount)
      Deprecated.
      Description copied from interface: ConnectionPool
      Optionally pre-create up to connectionCount connections so they are immediately ready for use.
      Specified by:
      preCreateConnections in interface ConnectionPool
      Parameters:
      connectionCount - the number of connections to pre-start.

    • getMaxDuration

      @ManagedAttribute("The maximum duration in milliseconds a connection can be used for before it gets closed") public long getMaxDuration()
      Deprecated.

      Get the max usage duration in milliseconds of the pool's connections. Values 0 and negative mean that there is no limit.

      This only guarantees that a connection cannot be acquired after the configured duration elapses, so that is only enforced when acquire() is called. If a pool stays completely idle for a duration longer than the value returned by this method, the max duration will not be enforced. It's up to the idle timeout mechanism (see HttpClient.getIdleTimeout()) to handle closing idle connections.

    • setMaxDuration

      public void setMaxDuration(long maxDurationInMs)
      Deprecated.

    • getActiveConnectionCount

      @ManagedAttribute(value="The number of active connections", readonly=true) public int getActiveConnectionCount()
      Deprecated.

    • getIdleConnectionCount

      @ManagedAttribute(value="The number of idle connections", readonly=true) public int getIdleConnectionCount()
      Deprecated.

    • getMaxConnectionCount

      @ManagedAttribute(value="The max number of connections", readonly=true) public int getMaxConnectionCount()
      Deprecated.

    • getConnectionCount

      @ManagedAttribute(value="The number of connections", readonly=true) public int getConnectionCount()
      Deprecated.

    • getPendingCount

      @ManagedAttribute(value="The number of pending connections", readonly=true) @Deprecated public int getPendingCount()
      Deprecated.
      use getPendingConnectionCount() instead
      Returns:
      the number of pending connections

    • getPendingConnectionCount

      @ManagedAttribute(value="The number of pending connections", readonly=true) public int getPendingConnectionCount()
      Deprecated.

    • isEmpty

      public boolean isEmpty()
      Deprecated.
      Specified by:
      isEmpty in interface ConnectionPool
      Returns:
      whether this ConnectionPool has no open connections

    • isMaximizeConnections

      @ManagedAttribute("Whether the pool tries to maximize the number of connections used") public boolean isMaximizeConnections()
      Deprecated.

    • setMaximizeConnections

      public void setMaximizeConnections(boolean maximizeConnections)
      Deprecated.

      Sets whether the number of connections should be maximized.

      Parameters:
      maximizeConnections - whether the number of connections should be maximized

    • acquire

      public Connection acquire()
      Deprecated.
      Description copied from interface: ConnectionPool

      Returns an idle connection, if available, or schedules the opening of a new connection and returns null.

      Specified by:
      acquire in interface ConnectionPool
      Returns:
      an available connection, or null

    • isActive

      public boolean isActive(Connection connection)
      Deprecated.
      Specified by:
