Detailed Description

Common reductor interface.

This is an abstract type, use reductor_fn and empty_reductor_fn concrete types.

Definition at line 46 of file reductor.hpp.

Member Function Documentation

complete_type complete ( ) const

inline

Completes and returns the state of the reduction.

The operation os move aware.

Definition at line 65 of file reductor.hpp.

complete_type current ( ) const

inline

Peeks at the current visible state of the reduction.

The operation is move aware. If an argument is passed, it updates the current state.

Definition at line 75 of file reductor.hpp.

operator bool ( ) const

inlineexplicit

Returns whether the reductor_fn will produce more values.

Definition at line 58 of file reductor.hpp.

reductor_fn_base& operator() ( InputTs2 &&... ins )

inline

Evaluates the next step of the reduction, passing the inputs ins to the reducing function.

Note: When operated on a const object, the it returns a new reductor_fn object. Otherwise, the operation is performed in-place and the object itself is returned. The operation is move-aware.
