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.
