Detailed Description

template<typename MappedType>
class isc::ha::HARelationshipMapper< MappedType >

Holds associations between objects and HA relationships.

There are at least two classes that require associations with the HA relationships: HAService and HAConfig. The HAImpl class may hold one or more instances of these classes. The library must be able to select appropriate instances depending on the partner name. This class associates partners with the relationships. Each partner may be associated with only one relationship. One relationship may be associated with many partners (e.g., primary and standby).

Template Parameters

MappedType

type of a mapped object (i.e., HAService or HAConfig).

Member Function Documentation

get() [1/2]

template<typename MappedType >

MappedTypePtr isc::ha::HARelationshipMapper< MappedType >::get ( ) const

inline

Returns the default mapped object.

Returns

Mapped object.

Exceptions

InvalidOperation

when there is no mapped object.

References isc_throw.

get() [2/2]

template<typename MappedType >

MappedTypePtr isc::ha::HARelationshipMapper< MappedType >::get ( const std::string & key ) const

inline

Retrieves mapped object by a key (e.g., partner name).

Parameters

key	typically a name of the partner belonging to a relationship.

Returns

Mapped object or null pointer if the object was not found.

Definition at line 65 of file ha_relationship_mapper.h.

getAll()

template<typename MappedType >

const std::vector< MappedTypePtr > & isc::ha::HARelationshipMapper< MappedType >::getAll ( ) const

inline

Returns all mapped objects.

Returns

A reference to a vector of mapped objects.

Definition at line 87 of file ha_relationship_mapper.h.

hasMultiple()

template<typename MappedType >

bool isc::ha::HARelationshipMapper< MappedType >::hasMultiple ( ) const

inline

Checks if the mapper has multiple objects.

Returns

true if the mapper includes multiple objects (e.g., HAService), false otherwise.

Definition at line 95 of file ha_relationship_mapper.h.

map()

template<typename MappedType >

void isc::ha::HARelationshipMapper< MappedType >::map ( const std::string & key, MappedTypePtr obj )

inline

Associates a key with the object.

Parameters

key	typically a name of a partner belonging to a relationship.
obj	mapped object.
