LatticeExpr(const LatticeExprNode &expr, const IPosition &latticeShape)
virtual IPosition doNiceCursorShape(uInt maxPixels) const
Return the best cursor shape.
virtual void handleMathTo(Lattice< T > &to, int oper) const
Handle the Math operators (+=, -=, *=, /=).
virtual void copyDataTo(Lattice< T > &to) const
Copy the data from this lattice to the given lattice.
virtual Bool hasLock(FileLocker::LockType) const
LockType
Define the possible lock types.
virtual MaskedLattice< T > * cloneML() const
Make a copy of the derived object (reference semantics).
virtual Bool isWritable() const
Returns False, as the LatticeExpr lattice is not writable.
virtual Bool lock(FileLocker::LockType, uInt nattempts)
Handle locking of the LatticeExpr which is delegated to all of its parts.
virtual LELCoordinates lelCoordinates() const
Returns the coordinates of the lattice expression.
virtual IPosition shape() const
Returns the shape of the Lattice including all degenerate axes (i.e.
LatticeExpr(const LatticeExprNode &expr)
Constructor from an arbitrary LatticeExprNode expression object.
LatticeExpr< T > & operator=(const LatticeExpr< T > &other)
Assignment (reference semantics)
virtual Bool doGetSlice(Array< T > &buffer, const Slicer §ion)
Do the actual get of the data.
virtual Bool isMasked() const
Has the object really a mask?
void init(const LatticeExprNode &expr)
Initialize the object from the expression.
LatticeExpr(const LatticeExpr< T > &other)
Copy constructor (reference semantics)
virtual Bool doGetMaskSlice(Array< Bool > &buffer, const Slicer §ion)
Do the actual get of the mask data.
virtual void doPutSlice(const Array< T > &sourceBuffer, const IPosition &where, const IPosition &stride)
An expression is not writable so this functions throws an exception.
this file contains all the compiler specific defines
LELArray< T > * lastChunkPtr_p
virtual const LatticeRegion * getRegionPtr() const
Get the region used (always returns 0).
template <class T, class U> class vector;
LatticeExpr()
Default constructor.
virtual ~LatticeExpr()
Destructor, does nothing.
bool Bool
Define the standard types used by Casacore.
virtual void resync()
Resynchronize the Lattice object with the lattice file.
