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

Description

A singleton that creates and returns Hashers by name.

HasherFactory 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.

Member Function Documentation

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.

Usually 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.

Exceptions

ref Rose::Combinatorics::Exception if hashType names an unsupported type.
