Intended use:

Public interface

 <h3>Review Status</h3><dl><dt>Date Reviewed:<dd>yyyy/mm/dd</dl>

Prerequisite

FunctionFactory

Etymology

This class is based on the Factory pattern, similar to the ApplicationObjectFactory

Synopsis

Example

Motivation

Template Type Argument Requirements (T)

Function must have a constructor for the form T(const Record&)

Thrown Exceptions

UnrecognizedFunctionError by create() if the Record field "functype" does not match a Function added via addFactory()
InvalidSerializationError by create() if
- Record does not contain a "functype" field containing a string
- the associated specific factory throws an InvalidSerializationError

Constructor & Destructor Documentation

template<class T >

casa::EclecticFunctionFactory< T >::EclecticFunctionFactory ( )

create an empty EclecticFunctionFactory

template<class T >

casa::EclecticFunctionFactory< T >::EclecticFunctionFactory ( const EclecticFunctionFactory< T > & factory )

create a shallow copy of another EclecticFunctionFactory

template<class T >

virtual casa::EclecticFunctionFactory< T >::~EclecticFunctionFactory ( ) [virtual]

delete this EclecticFunctionFactory.

Those specific factories added via addFactory() with own=True will be deleted.

Member Function Documentation

template<class T >

void casa::EclecticFunctionFactory< T >::addFactory	(	const String &	type,
		FunctionFactory< T > *	factory,
		Bool	own = `True`
	)

add a factory for creating a specific type of function, associating it with a given "functype" name.

template<class T >

virtual Function<T>* casa::EclecticFunctionFactory< T >::create ( const Record & ) const throw (FunctionFactoryError) [virtual]

create the Function object described in the given Record.

This implementation will use the value of the "functype" field to lookup the specific factory to use to create the function. That is, the the "functype" value will be matched against the type names loaded via addFactory().

Implements casa::FunctionFactory< T >.
