Detailed Description

General superclass for an algorithm.

This is a fairly abstract class, mainly used for implementing the backend "provider" interface.

Constructor & Destructor Documentation

Algorithm() [1/3]

QCA::Algorithm::Algorithm

(

const Algorithm &

from

)

Standard copy constructor.

Algorithm() [2/3]

QCA::Algorithm::Algorithm ( )

protected

Constructor for empty algorithm.

Algorithm() [3/3]

QCA::Algorithm::Algorithm ( const QString & type, const QString & provider )

operator=()

Algorithm & QCA::Algorithm::operator=

(

const Algorithm &

from

)

Assignment operator.

Parameters

from	the Algorithm to copy state from

References Algorithm().

type()

QString QCA::Algorithm::type

)

const

The name of the algorithm type.

provider()

Provider * QCA::Algorithm::provider

(

)

const

The name of the provider.

Each algorithm is implemented by a provider. This allows you to figure out which provider is associated

context() [1/2]

Provider::Context * QCA::Algorithm::context

(

)

The context associated with this algorithm

context() [2/2]

const Provider::Context * QCA::Algorithm::context

(

)

const

The context associated with this algorithm

change() [1/2]

void QCA::Algorithm::change

(

Provider::Context *

c

)

Set the Provider for this algorithm

Parameters

c	the context for the Provider to use

change() [2/2]

void QCA::Algorithm::change	(	const QString &	type,
		const QString &	provider )

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Parameters

type	the name of the algorithm to use
provider	the name of the preferred provider

takeContext()

Provider::Context * QCA::Algorithm::takeContext

(

)

Take the Provider from this algorithm
