TAO_Property_Evaluator_By_Name Class Reference
This class extends the TAO_Property_Evaluator to allow lookups based on the property name of interest. Since the property information is contained within an integer indexed array, lookups may occur in O(n) time, where n is the length of the array. To make lookups by name more efficient, TAO_Property_Evaluator_By_Name creates a mapping of property names to integer indicies, upon which lookups are guaranteed to be O(lg n). More...

Detailed Description
This class extends the TAO_Property_Evaluator to allow lookups based on the property name of interest. Since the property information is contained within an integer indexed array, lookups may occur in O(n) time, where n is the length of the array. To make lookups by name more efficient, TAO_Property_Evaluator_By_Name creates a mapping of property names to integer indicies, upon which lookups are guaranteed to be O(lg n).Constructor & Destructor Documentation

Construct an instance of TAO_Property_Evaluator that operates on an <offer> where the support for dynamic properties is dictated by <supports_dynamic_properties>.

Member Function Documentation
| int TAO_Property_Evaluator_By_Name::is_dynamic_property | ( | const char * | property_name | ) |
Returns 1 if the property whose name is <property_name> is defined and dynamic. If the property is undefined, this method will throw a Property_Undefined exception with impunity.
| CORBA::Any * TAO_Property_Evaluator_By_Name::property_value | ( | const char * | property_name | ) |
This method is identical to its counterpart in TAO_Property_Evaluator, except property_value first discovers the index through a string matching lookup.
| CORBA::TypeCode_ptr TAO_Property_Evaluator_By_Name::property_type | ( | const char * | property_name | ) |
This method is identical to its counterpart in TAO_Property_Evaluator, exception property_type first discovers the index through a string matching lookup.
| const CosTrading::Property * TAO_Property_Evaluator_By_Name::get_property | ( | const char * | property_name | ) |
| TAO_Property_Evaluator_By_Name& TAO_Property_Evaluator_By_Name::operator= | ( | const TAO_Property_Evaluator_By_Name & | ) | [private] |
