Reference frame for physical measures.

 <h3>Review Status</h3><dl><dt>Reviewed By:<dd>UNKNOWN<dt>Date Reviewed:<dd>before2004/08/25<dt>Test programs:<dd>tMeasure</dl>

Prerequisite

MRBase : the MeasRef base class
Quantum class
Measure class

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>

casa::MeasRef< Ms >::MeasRef ( )

Construct an empty MeasRef.

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

template<class Ms>

casa::MeasRef< Ms >::MeasRef ( const MeasRef< Ms > & other )

Copy constructor.

template<class Ms>

casa::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>

casa::MeasRef< Ms >::MeasRef	(	const uInt	tp,
		const Ms &	ep
	)

template<class Ms>

casa::MeasRef< Ms >::MeasRef	(	const uInt	tp,
		const MeasFrame &	mf
	)

template<class Ms>

casa::MeasRef< Ms >::MeasRef	(	const uInt	tp,
		const MeasFrame &	mf,
		const Ms &	ep
	)

template<class Ms>

casa::MeasRef< Ms >::~MeasRef ( )

Member Function Documentation

template<class Ms>

MeasRef casa::MeasRef< Ms >::copy ( ) [private]

Copy an instance.

template<class Ms>

void casa::MeasRef< Ms >::create ( ) [private]

Create an instance of MeasRef.

template<class Ms>

virtual Bool casa::MeasRef< Ms >::empty ( ) const [virtual]

Check if empty reference.

Implements casa::MRBase.

template<class Ms>

static const MeasFrame& casa::MeasRef< Ms >::frameComet	(	MRBase &	ref1,
		MRBase &	ref2
	)		`[static]`

template<class Ms>

static const MeasFrame& casa::MeasRef< Ms >::frameDirection	(	MRBase &	ref1,
		MRBase &	ref2
	)		`[static]`

template<class Ms>

static const MeasFrame& casa::MeasRef< Ms >::frameEpoch	(	MRBase &	ref1,
		MRBase &	ref2
	)		`[static]`

template<class Ms>

static const MeasFrame& casa::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& casa::MeasRef< Ms >::frameRadialVelocity	(	MRBase &	ref1,
		MRBase &	ref2
	)		`[static]`

template<class Ms>

virtual MeasFrame& casa::MeasRef< Ms >::getFrame ( ) [virtual]

Return the frame of reference.

Implements casa::MRBase.

template<class Ms>

virtual uInt casa::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 casa::MRBase.

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

template<class Ms>

virtual const Measure* casa::MeasRef< Ms >::offset ( ) const [virtual]

Return the offset (or 0)

Implements casa::MRBase.

template<class Ms>

Bool casa::MeasRef< Ms >::operator!= ( const MeasRef< Ms > & other ) const

Check if unequal MeasRef.

template<class Ms>

MeasRef& casa::MeasRef< Ms >::operator= ( const MeasRef< Ms > & other )

Copy assignment.

template<class Ms>

Bool casa::MeasRef< Ms >::operator== ( const MeasRef< Ms > & other ) const

Check if same MeasRef.

template<class Ms>

virtual void casa::MeasRef< Ms >::print ( ostream & os ) const [virtual]

Print a Measure.

Implements casa::MRBase.

template<class Ms>

virtual void casa::MeasRef< Ms >::set ( uInt tp ) [virtual]

Implements casa::MRBase.

template<class Ms>

void casa::MeasRef< Ms >::set ( const Ms & ep )

Set a new offset.

template<class Ms>

void casa::MeasRef< Ms >::set ( const Measure & ep )

Set a new offset (for internal use only)

template<class Ms>

virtual void casa::MeasRef< Ms >::set ( const MeasFrame & mf ) [virtual]

Set a new frame.

Implements casa::MRBase.

template<class Ms>

virtual void casa::MeasRef< Ms >::setType ( uInt tp ) [virtual]

Set the type.

Thrown Exceptions

AipsError if wrong Measure

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 casa::MRBase.

template<class Ms>

static const String& casa::MeasRef< Ms >::showMe ( ) [static]

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