Detailed Description

template<class T>
class casacore::EclecticFunctionFactory< T >

Intended use:

Public interface

Review Status

Date Reviewed:

yyyy/mm/dd

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

Member Function Documentation

addFactory()

template<class T>

void casacore::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.

References casacore::FunctionFactory< T >::FunctionFactory(), and casacore::True.

create()

template<class T>

virtual Function< T > * casacore::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 casacore::FunctionFactory< T >.
