Detailed Description

template<class FUNCTOR>
class bslstl::HashTable_ComparatorWrapper< FUNCTOR >

This class provides a wrapper around a functor that can compare two values and return a bool, so that the function call operator is always declared as const qualified.

TBD Provide an optimization for the case of an empty base functor, where we can safely const_cast want calling the base class operator.

Constructor & Destructor Documentation

template<class FUNCTOR>

bslstl::HashTable_ComparatorWrapper< FUNCTOR >::HashTable_ComparatorWrapper

(

)

Create a HashTable_ComparatorWrapper object wrapping a FUNCTOR that has its default value.

template<class FUNCTOR>

bslstl::HashTable_ComparatorWrapper< FUNCTOR >::HashTable_ComparatorWrapper

(

const FUNCTOR &

fn

)

[explicit]

Create a HashTable_ComparatorWrapper object wrapping a FUNCTOR that is a copy of the specified fn.

Member Function Documentation

template<class FUNCTOR>

void bslstl::HashTable_ComparatorWrapper< FUNCTOR >::swap

(

HashTable_ComparatorWrapper< FUNCTOR > &

other

)

Exchange the value of this object with the specified other object.

template<class FUNCTOR>

template<class ARG1_TYPE , class ARG2_TYPE >

bool bslstl::HashTable_ComparatorWrapper< FUNCTOR >::operator()	(	ARG1_TYPE &	arg1,
		ARG2_TYPE &	arg2
	)			const

Call the wrapped functor with the specified arg1 and arg2 (in that order) and return the result. Note that ARGn_TYPE will typically be deduced as a const type.

template<class FUNCTOR>

const FUNCTOR& bslstl::HashTable_ComparatorWrapper< FUNCTOR >::functor

(

)

const

Return a reference providing non-modifiable access to the hash functor wrapped by this object.
