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

HashTable_ComparatorWrapper() [1/2]

template<class FUNCTOR >

bslstl::HashTable_ComparatorWrapper< FUNCTOR >::HashTable_ComparatorWrapper ( )

inline

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

HashTable_ComparatorWrapper() [2/2]

template<class FUNCTOR >

bslstl::HashTable_ComparatorWrapper< FUNCTOR >::HashTable_ComparatorWrapper ( const FUNCTOR &  fn )

inlineexplicit

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

(

)

const

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

operator()()

template<class ARG1_TYPE , class ARG2_TYPE >

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

inline

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.
