Detailed Description

Wraps a particular unary operator.

You can use the methods of this class to change the routines that handle the operator and the types on which it operates. Instances of this class are implicitly shared - meaning calls on a copy of an instance are also visible on the original and all other copies.

Constructor & Destructor Documentation

ELAM::UnaryOperator::UnaryOperator

(

const UnaryOperator &

)

copy constructor, the instance will access the exact same operator as the original, any setting that is done in the copy is also done in the original and all other copies.

ELAM::UnaryOperator::UnaryOperator

(

)

instantiates an empty operator

ELAM::UnaryOperator::~UnaryOperator

(

)

deletes and operator

Member Function Documentation

QVariant ELAM::UnaryOperator::execute	(	const QVariant &	,
		Engine &
	)		const

calls the callback function associated with the type of the argument, throws an exception if there is no callback

UnaryOperatorCall ELAM::UnaryOperator::getCallback

(

QString

type

)

const

returns the callback function attached to the type or NULL if there is none

UnaryOperatorCall ELAM::UnaryOperator::getCallback

(

int

type

)

const

returns the callback function attached to the type or NULL if there is none

QList<int> ELAM::UnaryOperator::getTypeIds

(

)

const

returns all type IDs that have a valid callback in this operator

QStringList ELAM::UnaryOperator::getTypeNames

(

)

const

returns all type names that have a valid callback in this operator

bool ELAM::UnaryOperator::isNull

(

)

const

true if this operator has no callbacks

UnaryOperator& ELAM::UnaryOperator::operator=

(

const UnaryOperator &

op

)

the operator becomes a shared copy of op and abandones its old link

void ELAM::UnaryOperator::removeCallback

(

QString

)

removes the type from this operators list

void ELAM::UnaryOperator::removeCallback

(

int

)

removes the type from this operators list

void ELAM::UnaryOperator::setCallback	(	UnaryOperatorCall	callback,
		QString	type
	)

sets a callback function for the operator and a specific typ

Parameters

callback	the function to call, if it is null the type is deleted from this operators type list
type	the type of variable to work on, this must be a type registered with QVariant, if this type is already known to the operator its callback is replaced

void ELAM::UnaryOperator::setCallback	(	UnaryOperatorCall	callback,
		int	type
	)

sets a callback function for the operator and a specific typ

Parameters

callback	the function to call, if it is null the type is deleted from this operators type list
type	the type of variable to work on, this must be a type registered with QVariant, if this type is already known to the operator its callback is replaced
