Detailed Description

template<typename ArgumentType, typename StorageType = void>
class osvr::common::DeduplicatingFunctionWrapper< ArgumentType, StorageType >

A wrapper for a unary function that only calls its contained function when the input has changed.

Member Typedef Documentation

§ storage_type

template<typename ArgumentType , typename StorageType = void>

using osvr::common::DeduplicatingFunctionWrapper< ArgumentType, StorageType >::storage_type = typename std::conditional< std::is_same<StorageType, void>::value, typename std::remove_const< typename std::remove_reference<ArgumentType>::type>::type, StorageType>::type

Storage type: if not supplied via template parameter, inferred by removing const& from the argument type.

Member Function Documentation

§ operator()()

template<typename ArgumentType , typename StorageType = void>

return_type osvr::common::DeduplicatingFunctionWrapper< ArgumentType, StorageType >::operator()	(	argument_type	arg,
			...
	)

inline

Function call operator: passes call along to contained function if and only if (argument != last argument) or (first time being called)

Takes and throws away extra arguments so you don't have to wrap it in std::bind to get flexible calling ability.
