Detailed Description

Chooses the profile and a transport for a target object on which an invocation can be made.

A target object is represented by multiple profiles, which theoretically provides multiple paths to the same target object. This class helps in choosing the right profile, and pick a transport from cache (or create a new transport if needed) that represents the profile.

Member Function Documentation

bool TAO::Profile_Transport_Resolver::get_connection_timeout (  ACE_Time_Value &    max_wait_time )  [private]

Helper method to access get the connection timeout from the ORB.

ACE_INLINE CORBA::PolicyList * TAO::Profile_Transport_Resolver::inconsistent_policies (  void    )  const

void TAO::Profile_Transport_Resolver::init_inconsistent_policies (  ACE_ENV_SINGLE_ARG_DECL    )  throw (CORBA::SystemException)

Intialize the inconsistent policy list that this object has cached.

ACE_INLINE CORBA::Object_ptr TAO::Profile_Transport_Resolver::object (  void    )  const

Accessor for the target in use.

ACE_INLINE TAO_Profile * TAO::Profile_Transport_Resolver::profile (  void    )  const

Accessors and mutators for profile. Accessors and mutators for this class. The following methods are used by the clients of this class to access.

void TAO::Profile_Transport_Resolver::profile (  TAO_Profile *    pfile )

Accessors and mutators for profile. Accessors and mutators for this class. The following methods are used by the clients of this class to access.

void TAO::Profile_Transport_Resolver::resolve (  ACE_Time_Value *val    ACE_ENV_ARG_DECL )  throw (CORBA::SystemException)

Method where the bunch of the action takes place. This is the entry point from the TAO::Invocation_Adapter class. This method accesses the endpoint selector factory from the ORB_Core to decide on the strategy to be used for selecting the profile.

ACE_INLINE CORBA::PolicyList * TAO::Profile_Transport_Resolver::steal_inconsistent_policies (  void    )

ACE_INLINE TAO_Stub * TAO::Profile_Transport_Resolver::stub (  void    )  const

Accessor for TAO_Stub.

ACE_INLINE TAO_Transport * TAO::Profile_Transport_Resolver::transport (  void    )  const

Accessor for the transport reserved for this invocation.

ACE_INLINE void TAO::Profile_Transport_Resolver::transport_released (  void    )  const

Signal to let the resolver know that the transport has been released back to the cache.

bool TAO::Profile_Transport_Resolver::try_connect (  TAO_Transport_Descriptor_Interface *    desc, ACE_Time_Value *val    ACE_ENV_ARG_DECL )

This is a callback method used by the endpoint selectors, to delegate the responsibility of reserving a transport from the connection cache for this invocation.

Member Data Documentation

CORBA::PolicyList* TAO::Profile_Transport_Resolver::inconsistent_policies_ [private]

List of inconsistent policies. If current effective policies cause the invocation to raise CORBA::INV_POLICY exception, the conflicting/problematic policies are stored in this list. This is used by Parameters: Object::_validate_connection  method to inform clients about causes of invocation failure. Conflicting policies are only stored in this list if init_inconsistent_policies  method has been called prior to the beginning of invocation. This saves extra work of conflicting policies 'logging' when it's not needed. @NOTE: We don't use _var with a reason. Using _var would involve including the header file for atleast Policy_ForwardC.h, and that is what we precisely want to avoid.

bool TAO::Profile_Transport_Resolver::is_released_ [private]

Has the transport been idled?

CORBA::Object* TAO::Profile_Transport_Resolver::obj_ [private]

Target object.

TAO_Profile* TAO::Profile_Transport_Resolver::profile_ [private]

The profile that has been selected for this invocation.

TAO_Stub* TAO::Profile_Transport_Resolver::stub_ [private]

Stub object for the target object.

TAO_Transport* TAO::Profile_Transport_Resolver::transport_ [private]

The transport selected for this invocation.
