Templated base class for table vectors.
Internal
TabVecRep is the representation of a table vector.
TabVecRep is the counted referenced letter class for the envelope class TableVector. It is an abstract base class for the actual table vector classes TabVecScaCol and TabVecTemp.
All operations defined for TableVector are immediately passed to the corresponding virtual TabVecRep function. The header files TVecMath.h and TVecLogic.h declare all the mathematical and logical functions for TabVecRep.
A virtual function call only works when used with an object pointer or reference. To allow the use of virtual functions in value objects, an extra level of indirection is used. This is called the letter/envelope idiom and is described in "Advanced C++" by J. Coplien. Class TableVector is the envelope to the letters TabVecRep and its derivations.
| casa::TabVecRep< T >::TabVecRep | ( | ) |
Create empty table vector.
TabVecRep cannot be contructed by the user, because it is an abstract base class (it contains pure virtual functions).
| virtual casa::TabVecRep< T >::~TabVecRep | ( | ) | [virtual] |
Destruct the object.
| virtual void casa::TabVecRep< T >::assign | ( | const TabVecRep< T > & | ) | [virtual] |
Set to another table vector.
| Bool casa::TabVecRep< T >::conform | ( | const TabVecRep< T > & | vec | ) | const [inline] |
Test if vector shape conforms another table vector.

References casa::False, casa::TabVecRep< T >::nelements(), casa::nelements(), and casa::True.
| Bool casa::TabVecRep< T >::conform | ( | const Vector< T > & | vec | ) | const [inline] |
Test if vector shape conforms another vector.
Definition at line 192 of file TVec.h.

| TabVecTag casa::TabVecRep< T >::getTag | ( | ) | const [inline] |
| virtual void casa::TabVecRep< T >::getVal | ( | uInt | index, |
| T & | |||
| ) | const [pure virtual] |
Get a value.
Implemented in casa::TabVecTemp< T >, and casa::TabVecScaCol< T >.
| TabVecRep< T > * casa::TabVecRep< T >::link | ( | ) | [inline] |
Increments the reference count.

| uInt casa::TabVecRep< T >::ndim | ( | ) | const [inline] |
| virtual uInt casa::TabVecRep< T >::nelem | ( | ) | const [protected, virtual] |
Get nr of elements.
Reimplemented in casa::TabVecScaCol< T >.
| uInt casa::TabVecRep< T >::nelements | ( | ) | const [inline] |
Get nr of elements (ie.
vector length).

| void* casa::TabVecRep< T >::newVec | ( | ) | const |
Create a new temporary vector (for result of math operations).
TabVecTemp<T>& cannot be used, because the template instantiation mechanism instantiates TabVecTemp, which depends on TabVecRep and therefore gives errors.
| Bool casa::TabVecRep< T >::ok | ( | ) | const |
Check internal consistency.
| virtual void casa::TabVecRep< T >::putVal | ( | uInt | index, |
| const T & | |||
| ) | [pure virtual] |
Put a value.
Implemented in casa::TabVecTemp< T >, and casa::TabVecScaCol< T >.
| virtual void casa::TabVecRep< T >::set | ( | const T & | ) | [pure virtual] |
Set entire vector to a value.
Implemented in casa::TabVecTemp< T >, and casa::TabVecScaCol< T >.
| uInt casa::TabVecRep< T >::unlink | ( | ) | [inline] |
| void casa::TabVecRep< T >::validateConformance | ( | uInt | ) | const |
Check if vectors are comformant.
| virtual T casa::TabVecRep< T >::value | ( | uInt | index | ) | const [pure virtual] |
Get a value.
Implemented in casa::TabVecTemp< T >, and casa::TabVecScaCol< T >.
