Detailed Description

template<class T, class TValue>
class lti::sortExpensive< T, TValue >

Sorts elements in a list that are computationally expensive to compare.

You need to provide a pointer to a class member function that performs the expensive computation (e.g. area computation). This class sorts the list while performing the expensive computation exactly once for each element.

Member Function Documentation

template<class T , class TValue >

void lti::sortExpensive< T, TValue >::apply	(	std::list< T > &	aList,
		void *	callbackPtr,
		TValue(*)(void *callbackPtr, const T &)	computeValue
	)

Sort the elements in the given list.

Requires a function pointer that computes a double value for an object of type T. The function is assumed to be a class member function, therefore a pointer to an instance of that class (callbackPtr) is required (see www.function-pointer.org). See ltiObjectsFromMask for a usage example.

template<class T , class TValue >

virtual const char* lti::sortExpensive< T, TValue >::getTypeName

(

)

const [virtual]

returns the name of this type

Reimplemented from lti::object.
