Prerequisite

MaskedLattice (base class)

Etymology

This is a class designed to concatenate lattices along a specified axis

Synopsis

This is a class designed to concatenate lattices along a specified axis. This means you can join them together. E.g., join lattices of shape [10,20,30] and [10,20,40] into a lattice of shape [10,20,70].

In addition, you can increase the dimensionality and join lattices [10,20] and [10,20] to [10,20,2]. This is done by specifying the concatenation axis to be higher than currently exists in the input lattices

The LatticeConcat object does not copy the input lattices, it just references them. You can use the Lattice<T>::copyData(Lattice<T>) function to fill an output lattice with the concatenated input lattices.

If you use the putSlice function, be aware that it will change the underlying lattices if they are writable.

Example

// Make ArrayLattices 
 
 ArrayLattice<Float> al1(a1); al1.set(1.0);
 ArrayLattice<Float> al2(a2); al2.set(10.0);
 
// Turn these into MaskedLattices
 
 SubLattice<Float> ml1(al1, True);
 SubLattice<Float> ml2(al2, True);
 
// Concatenate along axis 1
 
 LatticeConcat<Float> lc (1);
 lc.setLattice(ml1);
 lc.setLattice(ml2);
 
// Make output
 
 ArrayLattice<Float> al3(lc.shape());
 SubLattice<Float> ml3(al3, True);
 
// Copy data to output (mask has to be copied separately)
 
 ml3.copyData(lc);

In this example no masks are involved. See tLatticeConcat for more examples.

Motivation

Image concatentation is a useful enduser requirement. An object of this class is contained by an ImageConcat object.

Constructor & Destructor Documentation

template<class T>

casacore::LatticeConcat< T >::LatticeConcat	(	uInt	axis,
		Bool	tempClose = `True`
	)

Constructor.

Argument axis specifies the concatenation axis (0 relative). If this is one more than the number of axes in the input lattices (set with function setLattice) then the resultant concatenated lattice has dimension one greater than that the input lattices. Argument tempClose specifies whether you wish all internal lattice copies to be opened/closed on demand, rather than just being left open. This prevents open file limits being reached

template<class T>

casacore::LatticeConcat< T >::LatticeConcat ( )

Default constructor.

Sets the concatenation axis to 0 and tempClose is True

template<class T>

casacore::LatticeConcat< T >::LatticeConcat ( const LatticeConcat< T > & other )

Copy constructor (reference semantics)

template<class T>

virtual casacore::LatticeConcat< T >::~LatticeConcat ( )

virtual

Destructor.

template<class T>

virtual LatticeConcat<T>* casacore::LatticeConcat< T >::cloneML ( ) const

virtual

Make a copy of the derived object (reference semantics).

Implements casacore::MaskedLattice< T >.

template<class T>

virtual Bool casacore::LatticeConcat< T >::doGetMaskSlice	(	Array< Bool > &	buffer,
		const Slicer &	section
	)

virtual

Do the actual get of the mask data.

The return value is always False, thus the buffer does not reference another array. Generally the user should use function getMaskSlice

Reimplemented from casacore::MaskedLattice< T >.

template<class T>

virtual Bool casacore::LatticeConcat< T >::doGetSlice	(	Array< T > &	buffer,
		const Slicer &	section
	)

virtual

Do the actual get of the data.

The return value is always False, thus the buffer does not reference another array. Generally the user should use function getSlice

Implements casacore::Lattice< T >.

template<class T>

virtual IPosition casacore::LatticeConcat< T >::doNiceCursorShape ( uInt maxPixels ) const

virtual

Return the best cursor shape.

This isn't very meaningful for a LatticeConcat Lattice since it isn't on disk ! But if you do copy it out, this is what you should use. The maxPixels aregument is ignored.

Reimplemented from casacore::LatticeBase.

template<class T>

virtual void casacore::LatticeConcat< T >::doPutSlice	(	const Array< T > &	sourceBuffer,
		const IPosition &	where,
		const IPosition &	stride
	)

virtual

Do the actual put of the data into the Lattice.

This will change the underlying lattices (if they are writable) that were used to create the LatticeConcat object. It throws an exception if not writable. Generally the user should use function putSlice

Implements casacore::Lattice< T >.

template<class T>

virtual void casacore::LatticeConcat< T >::flush ( )

Flush the data (but do not unlock).

By default the function does not do anything at all.

virtual

Resynchronize the Lattice object with the lattice file.

This function is only useful if no read-locking is used, ie. if the table lock option is UserNoReadLocking or AutoNoReadLocking. In that cases the table system does not acquire a read-lock, thus does not synchronize itself automatically.
