Detailed Description

Generic Connector interface definitions.

Base class for connector bridge object.

Todo:
Need to rename the class as TAO_Transport_Connector.


Constructor & Destructor Documentation

TAO_BEGIN_VERSIONED_NAMESPACE_DECL TAO_Connector::TAO_Connector CORBA::ULong  tag  ) 
 

Default constructor.

TAO_Connector::~TAO_Connector void   )  [virtual]
 

The destructor.


Member Function Documentation

virtual int TAO_Connector::cancel_svc_handler TAO_Connection_Handler svc_handler  )  [protected, pure virtual]
 

Cancel the passed cvs handler from the connector.

Implemented in TAO_IIOP_Connector.

int TAO_Connector::check_connection_closure TAO_Connection_Handler connection_handler  )  [protected, virtual]
 

Check whether the connection is not closed.

Return values:
0 The connection happens to be not closed, but is now open because an other thread managed to open the handler
-1 The connection is closed

virtual int TAO_Connector::check_prefix const char *  endpoint  )  [pure virtual]
 

Check that the prefix of the provided endpoint is valid for use with a given pluggable protocol.

Implemented in TAO_IIOP_Connector.

virtual int TAO_Connector::close void   )  [pure virtual]
 

Shutdown Connector bridge and concrete Connector.

Implemented in TAO_IIOP_Connector.

TAO_Transport * TAO_Connector::connect TAO::Profile_Transport_Resolver r,
TAO_Transport_Descriptor_Interface desc,
ACE_Time_Value timeout
[virtual]
 

To support pluggable we need to abstract away the details of the connect () method so it can be called from the invocation code independent of the actual transport protocol in use.

TAO_Profile * TAO_Connector::corbaloc_scan const char *  ior,
size_t &  len
[virtual]
 

Helper function to assist corbaloc parsing. The default simply validates the protocol identifyier and scans up to the next comma or slash. Any protocol that has a specific need, such as uiop, can override this method to provide a custom scanner. The profile returned is either null if this the ior does not match or an empty profile of the correct type, obtained from make_profile().

int TAO_Connector::create_connect_strategy void   )  [protected]
 

Create a connect strategy.

virtual TAO_Profile* TAO_Connector::create_profile TAO_InputCDR cdr  )  [pure virtual]
 

Create a profile for this protocol and initialize it based on the encapsulation in cdr

Implemented in TAO_IIOP_Connector.

virtual TAO_Transport* TAO_Connector::make_connection TAO::Profile_Transport_Resolver r,
TAO_Transport_Descriptor_Interface desc,
ACE_Time_Value timeout
[protected, pure virtual]
 

Make a connection.

Implemented in TAO_IIOP_Connector.

int TAO_Connector::make_mprofile const char *  ior,
TAO_MProfile mprofile
 

Parse a string containing a URL style IOR and return an MProfile. Verify that ior is in the correct format.

virtual TAO_Profile* TAO_Connector::make_profile  )  [protected, pure virtual]
 

Create a profile with a given endpoint.

Implemented in TAO_IIOP_Connector.

virtual char TAO_Connector::object_key_delimiter void   )  const [pure virtual]
 

Return the object key delimiter to use or expect.

Implemented in TAO_IIOP_Connector.

virtual int TAO_Connector::open TAO_ORB_Core orb_core  )  [pure virtual]
 

Initialize object and register with reactor.

Implemented in TAO_IIOP_Connector.

TAO_BEGIN_VERSIONED_NAMESPACE_DECL ACE_INLINE TAO_ORB_Core * TAO_Connector::orb_core void   )  [protected]
 

Return the TAO_ORB_Core pointer.

ACE_INLINE void TAO_Connector::orb_core TAO_ORB_Core orb_core  )  [protected]
 

Set the ORB Core pointer.

virtual int TAO_Connector::set_validate_endpoint TAO_Endpoint endpoint  )  [protected, pure virtual]
 

Set and validate endpoint. We need to do this to initialize our remote *_Addr's which have not been done during IOR decode.

Implemented in TAO_IIOP_Connector.

ACE_INLINE CORBA::ULong TAO_Connector::tag void   )  const
 

The tag identifying the specific ORB transport layer protocol. For example IOP::TAG_INTERNET_IOP == 0. The tag is used in the IOR to identify the type of profile included. IOR -> {{tag0, profile0} {tag1, profile1} ...}. The IOP module defines the ProfileId typedef to be a CORBA::ULong.

bool TAO_Connector::wait_for_connection_completion TAO::Profile_Transport_Resolver r,
TAO_Transport *&  transport,
ACE_Time_Value timeout
[protected, virtual]
 

Wait for connection completion. We have a transport that is not connected yet, wait until it is connected.

Return values:
true When we could use transport
Returns:
false When we can't use the transport
