Constructor Detail

### ClientBinding

    public ClientBinding(Address address,
                         ClientChannel channel,
                         java.lang.Object transportAssociation)

  Bind address to remote invocation channel.

### ClientBinding

    public ClientBinding(Address address,
                         ClientChannel channel,
                         java.lang.Object transportAssociation,
                         ServerManager serverManager)

  Bind address to local adapter.

### ClientBinding

    public ClientBinding(Address address,
                         SystemException ex)

  Bind address to a system exception. Placeholder for failed bindings

Method Detail

### getAddress

    public Address getAddress()

  Return the client address.

### getClientChannel

    public ClientChannel getClientChannel()

  Return the client channel. This is always available for both local and nonlocal bindings.

### getObjectAdapter

    public ObjectAdapter getObjectAdapter()

  Return the object adapter. This will return null if the binding is non-local.

### getPriority

    public int getPriority()

  Get binding priority. Low priorities are used first. The lowest order byte of the priority is inter-component priority, The second order byte is inter-profile priority, The third order byte is inter-refrerence prioriy The highest order byte is the channel state / adapter priority.

### setPriority

    public void setPriority(int priority)

  Set the binding priority. Lower values are used first. This should be set with respect to the current priority, changing only the appropriate bits.

### hashCode

    public int hashCode()

  Overrides:
    `hashCode` in class `java.lang.Object`

### equals

    public boolean equals(java.lang.Object obj)

  Overrides:
    `equals` in class `java.lang.Object`

### local_invoke

    public boolean local_invoke()

  True if the target can accept local invocations. The object reference operations such as is_a are available for local invocation whenever getObjectAdapter returns non null.

### create_request

    public ClientRequest create_request(Object target,
                                        java.lang.String operation,
                                        boolean response_expected)

  Create a request. If this is the first request on this channel then client_connect will be called on all ChannelInterceptor before returning the request. This may return null if the channel is unable to create a request. This just calls create_request on the channel with the binding's address and the specified target.
  Parameters:
    `target` - The target of the request.
    `address` - The target address. If the target has been redirected this may not correspond to the target's ior.

### create_request_local

    public LocalClientRequest create_request_local(ORB orb,
                                                   Object target,
                                                   java.lang.String operation,
                                                   boolean response_expected,
                                                   Address[] adresses)

  This is a factory method for creation a new Local Client Request. This is necessary for having a clean handling of the request_id.
  Parameters:
    `orb` - ORB
    `target` - target object for the request
    `operation` - operation
    `response_expected` - oneway call or not
    `adresses` - all the adresses of the target
  Returns:
    A new instance of this class.

### create_locate_request

    public ClientRequest create_locate_request(Object target)

  Create a locate request. This may return null if the channel is unable to create a request. This just calls create_locate_request on the channel with the binding's address and the specified target.
  Parameters:
    `target` - The target of the request.

### servant_preinvoke

    public ServantObject servant_preinvoke(java.lang.String operation,
                                           java.lang.Class expectedType)
                                    throws ForwardRequest

  Calls servant_preinvoke on the adapter. This may return null if a retry is indicated.

### servant_postinvoke

    public void servant_postinvoke(ServantObject srvObject)

  Calls servant_postinvoke on the adapter.

### locate

    public boolean locate()
                   throws ForwardRequest

  Calls locate on the adapter.

### is_a

    public boolean is_a(java.lang.String repository_id)
                 throws ForwardRequest

  Calls is_a on the adapter.

### get_interface_def

    public Object get_interface_def()
                             throws ForwardRequest

  Calls get_interface_def on the adapter.

### get_domain_managers

    public DomainManager[] get_domain_managers()
                                        throws ForwardRequest

  Calls get_domain_managers on the adapter.

### get_component

    public Object get_component()
                         throws ForwardRequest

  Calls get_component on the adapter.
