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.
| casacore::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 |
Destruct the object.
|
virtual |
Set to another table vector.
|
inline |
Test if vector shape conforms another table vector.
Definition at line 189 of file TVec.h.
References casacore::False, casacore::TabVecRep< T >::nelements(), casacore::nelements(), and casacore::True.
|
inline |
Test if vector shape conforms another vector.
Definition at line 192 of file TVec.h.
References casacore::False, casacore::ArrayBase::nelements(), casacore::nelements(), and casacore::True.
|
inline |
|
pure virtual |
Get a value.
Implemented in casacore::TabVecTemp< T >, and casacore::TabVecScaCol< T >.
|
inline |
Increments the reference count.
Definition at line 197 of file TVec.h.
Referenced by casacore::TableVector< T >::TableVector().
|
inline |
|
protectedvirtual |
Get nr of elements.
Reimplemented in casacore::TabVecScaCol< T >.
|
inline |
Get nr of elements (ie.
vector length).
Definition at line 184 of file TVec.h.
Referenced by casacore::TabVecRep< T >::conform().
| void* casacore::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 casacore::TabVecRep< T >::ok | ( | ) | const |
Check internal consistency.
|
pure virtual |
Put a value.
Implemented in casacore::TabVecTemp< T >, and casacore::TabVecScaCol< T >.
|
pure virtual |
Set entire vector to a value.
Implemented in casacore::TabVecTemp< T >, and casacore::TabVecScaCol< T >.
|
inline |
| void casacore::TabVecRep< T >::validateConformance | ( | rownr_t | ) | const |
Check if vectors are comformant.
|
pure virtual |
Get a value.
Implemented in casacore::TabVecTemp< T >, and casacore::TabVecScaCol< T >.
