Rose::Combinatorics::Hasher::HasherFactory Class Reference

Description

HasherFactory is a singleton that creates and returns Hashers by name.

Hasher factory contains a map of names to HasherMaker . When createHasher is passed a name, it will attempt to create the correct Hasher and pass it back.
Users can add Hashers to HasherFactory using @HasherMaker. HasherFactory is created when Instance is first called. Generally this is done at module initialization time.

Instance()

static HasherFactory & Rose::Combinatorics::Hasher::HasherFactory::Instance ( )

static

Returns a reference to the HasherFactory singleton.

Creates a HasherFactory if necessary

registerMaker()

void Rose::Combinatorics::Hasher::HasherFactory::registerMaker	(	const std::string &	hashType,
		IHasherMaker *	createHasherPtr
	)

Adds a new @HasherMaker to the HasherFactory.

Ussually called by the HasherMaker constructor

createHasher()

std::shared_ptr< Hasher > Rose::Combinatorics::Hasher::HasherFactory::createHasher

(

const std::string &

hashType

)

const

Creates a registered Hasher by type from the map.

Parameters

[in]

hashType

The type of the Hasher to create. e.g. FNV

Returns

A Hasher of the correct type in an std::shared_ptr
