Detailed Description

template<class Ms>
class casacore::MeasRef< Ms >

Reference frame for physical measures.

Intended use:

Prerequisite

Etymology

From Measure and Reference frame

Synopsis

MeasRef specifies the reference frame for a physical quantity specified by one of the derived Measure classes (e.g. MEpoch). It is derived from MRBase, which describes the class.

MeasRef containres are created using the Measure::Ref class (e.g. MDirection::Ref).

Example

See Measure for an example

Motivation

To gather all reference frame information in the one class.

Constructor & Destructor Documentation

template<class Ms>
casacore::MeasRef< Ms >::MeasRef ( )

Construct an empty MeasRef.

I.e. it will have a standard, default, type; no offsets and Frame.

template<class Ms>
casacore::MeasRef< Ms >::MeasRef ( const MeasRef< Ms > &  other)

Copy constructor.

template<class Ms>
casacore::MeasRef< Ms >::MeasRef ( const uInt  tp)
explicit

Construct a reference with specified type, offset and Frame.


Caution: The following should really be (and should still be called as), but compiler does not accept it, due to incomplete definition when called in MeasBase:
MeasRef(Ms::Types tp); Furthermore, default arguments are not supported with templated classes:

template<class Ms>
casacore::MeasRef< Ms >::MeasRef ( const uInt  tp,
const Ms &  ep 
)
template<class Ms>
casacore::MeasRef< Ms >::MeasRef ( const uInt  tp,
const MeasFrame mf 
)
template<class Ms>
casacore::MeasRef< Ms >::MeasRef ( const uInt  tp,
const MeasFrame mf,
const Ms &  ep 
)
template<class Ms>
casacore::MeasRef< Ms >::~MeasRef ( )

Member Function Documentation

template<class Ms>
MeasRef casacore::MeasRef< Ms >::copy ( )
private

Copy an instance.

template<class Ms>
void casacore::MeasRef< Ms >::create ( )
private

Create an instance of MeasRef.

template<class Ms>
virtual Bool casacore::MeasRef< Ms >::empty ( ) const
virtual

Check if empty reference.

Implements casacore::MRBase.

template<class Ms>
static const MeasFrame& casacore::MeasRef< Ms >::frameComet ( MRBase ref1,
MRBase ref2 
)
static
template<class Ms>
static const MeasFrame& casacore::MeasRef< Ms >::frameDirection ( MRBase ref1,
MRBase ref2 
)
static
template<class Ms>
static const MeasFrame& casacore::MeasRef< Ms >::frameEpoch ( MRBase ref1,
MRBase ref2 
)
static
template<class Ms>
static const MeasFrame& casacore::MeasRef< Ms >::framePosition ( MRBase ref1,
MRBase ref2 
)
static

Return the first frame which has specified information.

Checking is done in argument order.

Thrown Exceptions

  • AipsError if neither reference has a frame or the proper type
template<class Ms>
static const MeasFrame& casacore::MeasRef< Ms >::frameRadialVelocity ( MRBase ref1,
MRBase ref2 
)
static
template<class Ms>
virtual MeasFrame& casacore::MeasRef< Ms >::getFrame ( )
virtual

Return the frame of reference.

Implements casacore::MRBase.

template<class Ms>
virtual uInt casacore::MeasRef< Ms >::getType ( ) const
virtual

Return the type of the reference
Caution: the following should really be (and should be interpreted as), but cannot create a virtual function:
Ms::Types getType();

Implements casacore::MRBase.

Referenced by casacore::SDPointingHandler::directionRefType().

template<class Ms>
virtual const Measure* casacore::MeasRef< Ms >::offset ( ) const
virtual

Return the offset (or 0)

Implements casacore::MRBase.

template<class Ms>
Bool casacore::MeasRef< Ms >::operator!= ( const MeasRef< Ms > &  other) const

Check if unequal MeasRef.

template<class Ms>
MeasRef& casacore::MeasRef< Ms >::operator= ( const MeasRef< Ms > &  other)

Copy assignment.

template<class Ms>
Bool casacore::MeasRef< Ms >::operator== ( const MeasRef< Ms > &  other) const

Check if same MeasRef.

template<class Ms>
virtual void casacore::MeasRef< Ms >::print ( ostream &  os) const
virtual

Print a Measure.

Implements casacore::MRBase.

template<class Ms>
virtual void casacore::MeasRef< Ms >::set ( uInt  tp)
virtual

Implements casacore::MRBase.

template<class Ms>
void casacore::MeasRef< Ms >::set ( const Ms &  ep)

Set a new offset.

template<class Ms>
void casacore::MeasRef< Ms >::set ( const Measure ep)

Set a new offset (for internal use only)

template<class Ms>
virtual void casacore::MeasRef< Ms >::set ( const MeasFrame mf)
virtual

Set a new frame.

Implements casacore::MRBase.

template<class Ms>
virtual void casacore::MeasRef< Ms >::setType ( uInt  tp)
virtual

Set the type.

Thrown Exceptions


Caution: the following should really be (and should be called as), but compiler does not accept it, since a virtual function:
void set(Ms::Types tp);

Implements casacore::MRBase.

template<class Ms>
static const String& casacore::MeasRef< Ms >::showMe ( )
static

Check the type of Measure the reference can be used for.
