std.algorithm.searching.BoyerMooreFinder/boyerMooreFinder - multiple declarations

Function boyerMooreFinder

Sets up Boyer-Moore matching for use with find below. By default, elements are compared for equality.

BoyerMooreFinder!(binaryFun!pred,Range) boyerMooreFinder(alias pred, Range) (
  Range needle
)
if (isRandomAccessRange!Range && hasSlicing!Range || isSomeString!Range);

BoyerMooreFinder allocates GC memory.

Parameters

NameDescription
pred Predicate used to compare elements.
needle A random-access range with length and slicing.

Returns

An instance of BoyerMooreFinder that can be used with find() to invoke the Boyer-Moore matching algorithm for finding of needle in a given haystack.

Example

auto bmFinder = boyerMooreFinder("TG");

string r = "TAGTGCCTGA";
// search for the first match in the haystack r
r = bmFinder.beFound(r);
writeln(r); // "TGCCTGA"

// continue search in haystack
r = bmFinder.beFound(r[2 .. $]);
writeln(r); // "TGA"

Struct BoyerMooreFinder

Parameters
