:relfileprefix: ../../../
:mrdocs:

Create a searcher by moving from `original` using `basicAllocator`.

== Synopsis

Declared in `<bslstl_boyermoorehorspoolsearcher.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
BoyerMooreHorspoolSearcher(
    xref:BloombergLP/bslmf/MovableRef.adoc[BloombergLP::bslmf::MovableRef<BoyerMooreHorspoolSearcher>] original,
    xref:BloombergLP/bslma/Allocator.adoc[BloombergLP::bslma::Allocator]* basicAllocator);
----

== Description

The new object has the same state ‐‐ `needleFirst()`, `needleLast()`, `hash()`, and `equal()` ‐‐ as `original`. The specified `basicAllocator` is used to supply memory. If `basicAllocator` is 0, the currently installed default allocator is used. The state of `original` is moved (in constant time) to the new searcher if `basicAllocator == original.allocator()`, and is move‐inserted (in linear time) using `basicAllocator` otherwise. The `original` object is left in an unspecified (valid) state.
