Detailed Description

This class implements the basic interface for supporting multiple profiles.

Multiple profiles can be treated either as a circular queue or a linear array of profiles. It is assumed that locking will only be required when a profile list is associated with a TAO_Stub. Thus when the TAO_Stub accepts ownership of an MProfile it also assumes responsibility for controling access (i.e. locking).


Constructor & Destructor Documentation

TAO_MProfile::TAO_MProfile ( CORBA::ULong  sz = 0)
TAO_MProfile::TAO_MProfile ( const TAO_MProfile mprofiles)

**NOTE: IF mprofiles->last_ > 0, THEN this->size_ will be set to mprofiles->last_. Otherwise this->size_ - mprofiles->size_. Furthermore, current_ is set back to 0! i.e. rewound. The reference count on any profiles in mprofiles is increment when their references (i.e. pointers) are copied.

TAO_MProfile::~TAO_MProfile ( void  )

Destructor: decrements reference count on all references profiles!


Member Function Documentation

int TAO_MProfile::add_profile ( TAO_Profile pfile)

Return the index of this entry or -1 if it can not be added. reference count on profile in incremented!

int TAO_MProfile::add_profiles ( TAO_MProfile pfiles)

append the profiles in pfiles to this object. The count will be incremented on the individual profile objects.

void TAO_MProfile::cleanup ( void  ) [private]

Helper method to implement the destructor.

void TAO_MProfile::create_policy_list ( void  ) [protected]

This method handle the dynamic allocation of the data member <policy_list_>.

void TAO_MProfile::forward_from ( TAO_MProfile mprofiles)

Set a pointer to the MProfile whose 'current' TAO_Profile was forwarded This object is the set of forwarding profiles.

TAO_MProfile * TAO_MProfile::forward_from ( void  )

Returns a pointer to the profile which was forwarded.

TAO_Profile * TAO_MProfile::get_cnext ( void  )

Treat as a circular list.

TAO_Profile * TAO_MProfile::get_cprev ( void  )

Assume a circular list of profiles.

TAO_PHandle TAO_MProfile::get_current_handle ( void  )

Returns the index for the current profile.

TAO_PHandle TAO_MProfile::get_current_handle ( void  ) const

Returns the index for the current profile.

TAO_Profile * TAO_MProfile::get_current_profile ( void  )

Return a pointer to the current profile, will not increment reference pointer.

TAO_Profile * TAO_MProfile::get_next ( void  )

Get next profile in list, return 0 at end of list.

TAO_Profile * TAO_MProfile::get_prev ( void  )

Get previous profile, stop at beginning of list and return 0.

TAO_Profile * TAO_MProfile::get_profile ( TAO_PHandle  handle)

Return a pointer to the profile referenced by handle void.

const TAO_Profile * TAO_MProfile::get_profile ( CORBA::ULong  slot) const

Return the profile at position <slot>. If <slot> is out of range it returns 0.

int TAO_MProfile::give_profile ( TAO_Profile pfile,
int  share = 0 
)

Return the index of this entry or -1 if it can not be added. this object assumes ownership of this profile!!

int TAO_MProfile::give_shared_profile ( TAO_Profile pfile) [private]

A helper to give_profile to be used when share is true. This method is used primarily to help the corbaloc parser create a single profile with multiple endpoints rather than constructing multiple profiles with 1 endpoint per.

int TAO_MProfile::grow ( CORBA::ULong  sz)

increase the number of profiles this object can hold. NOT THREAD SAFE

CORBA::ULong TAO_MProfile::hash ( CORBA::ULong  max)

use all registered profiles. The hash() method is called on each profile and the results are averaged together. NON-THREAD SAFE.

void TAO_MProfile::init_policy_list ( void  ) [protected]

Initialize the policy list, demarsharling the policy.

CORBA::Boolean TAO_MProfile::is_equivalent ( const TAO_MProfile rhs)

Returns true of there is at least one profile in first which is_equivalent with at least one profile in second. NON-THREAD SAFE, relies on some other entity to guarentee the profiles will not change during the call.

TAO_MProfile & TAO_MProfile::operator= ( const TAO_MProfile mprofiles)

Assigment operator.

TAO_Profile ** TAO_MProfile::pfiles ( void  ) const [protected]

Return the complete list of profiles, this object retains ownership!

void TAO_MProfile::policy_list ( CORBA::PolicyList *  policy_list)

Sets the policies list associated with the profiles owned by the TAO_MProfile.

CORBA::PolicyList * TAO_MProfile::policy_list ( void  )

Gets the policies list associated with the profiles owned by the TAO_MProfile.

CORBA::ULong TAO_MProfile::profile_count ( void  ) const

Returns the number of profiles stored in the list (last_+1).

int TAO_MProfile::remove_profile ( const TAO_Profile pfile)

remove from this MProfile any profiles which also appear in pfiles.

int TAO_MProfile::remove_profiles ( const TAO_MProfile pfiles)

remove from this MProfile any profiles which also appear in pfiles.

void TAO_MProfile::rewind ( void  )

Sets the current slot back to 0.

int TAO_MProfile::set ( const TAO_MProfile mprofile)

Inits this to the values of mprofile. NOTE: We use mprofile->last_ instead of mprofile->size_ to set this->size_. This is so we can use set () to trim a profile list!! NOT THREAD SAFE

int TAO_MProfile::set ( CORBA::ULong  sz)

Inits MProfile to hold sz TAO_Profiles. NOT THREAD SAFE

CORBA::ULong TAO_MProfile::size ( void  ) const

return the maximum number of profiles that can be stored in this container, (size_+1)


Friends And Related Function Documentation

friend class TAO_Profile [friend]

Stores the policy list for the profile of this MProfile.


Member Data Documentation

Points to the next profile to be used. 0 ... size_.

Used for chaning references when the current profile is forwarded. Note, this will only be valid for an MProfile which contains a list of forward_profiles for some initial or base profile. This is a backward reference to the profile list which received the relocate message. The actual profile what was forwarded will be forward_from_->get_current_profile ()

Index plus 1 of last valid entry! May be < size_.

TAO_SYNCH_RECURSIVE_MUTEX TAO_MProfile::mutex_ [protected]

Mutex used to make sure that only one policy list is created.

Actual list of profiles.

CORBA::PolicyList* TAO_MProfile::policy_list_ [protected]

Max size of array.
