Spec SorterSpec
Sorts all elements using a custom compare function.

Extends Pool
All Extended Pool
All Subcl's SorterConfig, SorterConfigSize
Defined in <seqan/pipe.h>
Signature template <typename TValue, typename TConfig> struct Pool<TValue, SorterSpec<TConfig > >;

Template Parameters

TConfig Configuration Spec. Defines compare function, size type, and file type.
TValue The value type, that is the type of the stream elements.

Interface Function Overview

Interface Functions Inherited From Pool

Detailed Description

The Pool's input/output type is TValue and the size type is determined by the TConfig.

If there exists an explicit function mapping input elements to their destined positions in the output stream, MapperSpec should be preferred.
