int TAO_Notify_Constraint_Visitor::bind_structured_event ( const CosNotification::StructuredEvent & s_event )

Put the event data into our hash map.

CORBA::Boolean TAO_Notify_Constraint_Visitor::evaluate_constraint ( ETCL_Constraint * root )

Returns true if the event satisfies the constraint represented by the the expression tree rooted at root, false if it doesn't. If an error occurs during the process, the traversal automatically fails.

Member Data Documentation

CORBA::String_var TAO_Notify_Constraint_Visitor::current_name_ [protected]

Holder for a string name in the event fields fixed_header, variable_header, or filterable_data.

CORBA::Any_var TAO_Notify_Constraint_Visitor::current_value_ [protected]

Holder for a value found in the event fields filterable_data, variable_header or remainder_of_body.

CORBA::String_var TAO_Notify_Constraint_Visitor::domain_name_ [protected]

Storage for string names under the structured event's 'fixed_header' field.

CORBA::String_var TAO_Notify_Constraint_Visitor::event_name_ [protected]

ACE_Hash_Map_Manager<ACE_CString, CORBA::Any, ACE_Null_Mutex> TAO_Notify_Constraint_Visitor::filterable_data_ [protected]

Used to lookup names and values in the event's 'filterable_data' field.

const size_t TAO_Notify_Constraint_Visitor::filterable_data_size_ = 31 [static, protected]

Size of filterable_data_ hash map.

Todo:: define inline once VC6 support is deprecated.

structured_event_field TAO_Notify_Constraint_Visitor::implicit_id_ [protected]

Storage for the type of implicit id the component has (if any).

ACE_Hash_Map_Manager<ACE_CString, structured_event_field, ACE_Null_Mutex> TAO_Notify_Constraint_Visitor::implicit_ids_ [protected]

Lookup table for the implicit ids, to avoid string comparisons in derived visitors.

const size_t TAO_Notify_Constraint_Visitor::implicit_ids_size_ = 27 [static, protected]

Size of implicit_ids_ hash map.

Note:: A fixed set of 9 keys are stored in this map. In the absence of a minimal perfect hash, ACE's default hash_pjw() and a hash size of 27 ensures each element is hashed to a unique bucket.
