Pex

| Class Specialization Pex Provides a fast approximate string matching filter that splits the needle into several pieces that are searched with a multiple exact string matching algorithm and later verified.

Hierarchical | NonHierarchical
Pattern<TNeedle, Pex<TVerification,TMultiFinder> > Include Headers seqan/find.h Parameters
TNeedle | The needle type. Types: String
TVerification | Determines if the hierarchical verification proposed by Navarro and Baeza-Yates is used or not. Types: Hierarchical, NonHierarchical
TMultiFinder | Specifies the algorithm for the multiple exact string matching algorithm Types: AhoCorasick
Remarks There are two defaults available PexHierarchical and PexNonHierarchical (e.g. Pattern<String<char> ,PexHierarchical>) that both use the AhoCorasick algorithm for the multiple exact string matching. Specialization of Pattern Specializations
Hierarchical | By using this Specialization the hierarchical verification is enabled.
NonHierarchical | By using this Specialization the hierarchical verification is disabled.
