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

TAO_Property_Evaluator_By_Name::TAO_Property_Evaluator_By_Name const CosTrading::PropertySeq &properties  ACE_ENV_ARG_DECL,
CORBA::Boolean  supports_dp = 1
throw (CosTrading::DuplicatePropertyName, CosTrading::IllegalPropertyName)
 

TAO_Property_Evaluator_By_Name::TAO_Property_Evaluator_By_Name CosTrading::Offer offer,
CORBA::Boolean  supports_dp = 1
 

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

const CosTrading::Property * TAO_Property_Evaluator_By_Name::get_property const char *  property_name  ) 
 

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.

TAO_Property_Evaluator_By_Name& TAO_Property_Evaluator_By_Name::operator= const TAO_Property_Evaluator_By_Name  )  [private]
 

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.

CORBA::Any * TAO_Property_Evaluator_By_Name::property_value const char *property_name  ACE_ENV_ARG_DECL  )  throw (CosTradingDynamic::DPEvalFailure)
 

This method is identical to its counterpart in TAO_Property_Evaluator, except property_value first discovers the index through a string matching lookup.
