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 ( CORBA::ULong sz )

Inits MProfile to hold sz TAO_Profiles. NOT THREAD SAFE

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

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

TAO_PHandle TAO_MProfile::current_ [private]

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

TAO_MProfile* TAO_MProfile::forward_from_ [private]

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 ()

CORBA::Boolean TAO_MProfile::is_policy_list_initialized_ [protected]

TAO_PHandle TAO_MProfile::last_ [private]

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.

TAO_Profile** TAO_MProfile::pfiles_ [private]

Actual list of profiles.

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

TAO_PHandle TAO_MProfile::size_ [private]

Max size of array.
