Detailed Description

template<typename ValueType, typename MatchFunc, typename ObjType1, typename ObjType2 = void>
class CDPL::Chem::PropertyMatchExpression< ValueType, MatchFunc, ObjType1, ObjType2 >

PropertyMatchExpression.

Template Parameters

ValueType	The type of the checked property values.
MatchFunc	The type of a binary functor class that implements the logic of testing the target property values against the query property values. The overloaded function call operator is required to take the target property value as its first argument and the query value as the second argument (both provided as `const` reference to `ValueType`). The returned result must be implicitly convertible to type `bool` (`true` indicates a match, `false` a mismatch).
ObjType1	The type of the primary query/target objects for which the expression gets evaluated.
ObjType2	The type of secondary query/target objects which provide auxiliary information for expression evaluation.

Member Typedef Documentation

◆ SharedPointer

template<typename ValueType , typename MatchFunc , typename ObjType1 , typename ObjType2 = void>

typedef std::shared_ptr<PropertyMatchExpression> CDPL::Chem::PropertyMatchExpression< ValueType, MatchFunc, ObjType1, ObjType2 >::SharedPointer

A reference-counted smart pointer [SHPTR] for dynamically allocated PropertyMatchExpression instances.

◆ PropertyFunction

template<typename ValueType , typename MatchFunc , typename ObjType1 , typename ObjType2 = void>

typedef std::function<ValueType(const ObjType1&, const ObjType2&)> CDPL::Chem::PropertyMatchExpression< ValueType, MatchFunc, ObjType1, ObjType2 >::PropertyFunction

Type of the generic functor class used to store user-defined property accessor functions.

PropertyFunction allows to wrap any function pointer or function object compatible with a return type of ValueType and two arguments of type const ObjType1& and const ObjType2& (see [FUNWRP]).

◆ PropertyMatchExpression() [1/2]

template<typename ValueType , typename MatchFunc , typename ObjType1 , typename ObjType2 = void>

CDPL::Chem::PropertyMatchExpression< ValueType, MatchFunc, ObjType1, ObjType2 >::PropertyMatchExpression ( const PropertyFunction & property_func )

inline

Constructs a PropertyMatchExpression instance that performs query/target object equivalence tests based on the property values returned by property_func.

Parameters

property_func A PropertyMatchExpression::PropertyFunction2 instance that wraps the specified property value accessor function.

◆ PropertyMatchExpression() [2/2]

template<typename ValueType , typename MatchFunc , typename ObjType1 , typename ObjType2 = void>

CDPL::Chem::PropertyMatchExpression< ValueType, MatchFunc, ObjType1, ObjType2 >::PropertyMatchExpression	(	const ValueType &	value,
		const PropertyFunction &	property_func
	)

inline

Constructs a PropertyMatchExpression instance that performs query/target object equivalence tests based on the target object property values returned by property_func and the specified query value.

Parameters

value	The query property value.
property_func	A PropertyMatchExpression::PropertyFunction2 instance that wraps the specified target property value accessor function.

Member Function Documentation

◆ operator()()

template<typename ValueType , typename MatchFunc , typename ObjType1 , typename ObjType2 >

bool CDPL::Chem::PropertyMatchExpression< ValueType, MatchFunc, ObjType1, ObjType2 >::operator()	(	const ObjType1 &	query_obj1,
		const ObjType2 &	query_obj2,
		const ObjType1 &	target_obj1,
		const ObjType2 &	target_obj2,
		const Base::Any &	aux_data
	)		const

virtual

Checks whether the value of the target object propery matches the query property value.

The actual equivalence test between the query and target property values is performed by an instance of the function object type that was provided as template argument for MatchFunc.

Parameters

query_obj1	The primary query object.
query_obj2	The secondary query object.
target_obj1	The primary target object.
target_obj2	The secondary target object.
aux_data	Provides auxiliary information for the evaluation of the expression (ignored).

Returns: true if the target property value matches the query property value under the conditions defined by MatchFunc, and false otherwise.
