Detailed Description

template<typename T, typename U>
class EpetraExt::Transform< T, U >

Base Class for all Epetra Transform Operators.

This is the abstract definition for all Epetra Transform Operators. Depending on the type of Transform, several specializations are available: Structural, SameType, InPlace, View.

Constructor & Destructor Documentation

template<typename T, typename U> EpetraExt::Transform< T, U >::Transform (   )  [inline, protected]

Default constructor, protected to allow only derived classes to use. Initializes attributes origObj_ and newObj_ to 0.

---

Member Function Documentation

template<typename T, typename U> bool EpetraExt::Transform< T, U >::analyze (  OriginalTypeRef  orig  )  [virtual]

Initial analysis phase of transform. Returns true if the transform is possible allowing methods construct(), fwd() and rvs() to be successfully utilized. Preconditions: Invariants: Postconditions: The default implementation calls method operator() and stores the resulting object in an internal attribute newObj_.

template<typename T, typename U> Transform< T, U >::NewTypeRef EpetraExt::Transform< T, U >::construct (   )  [virtual]

Construction of new object as a result of the transform. Preconditions: Invariants: Postconditions: The default implementation returns internal attribute newObj_.

template<typename T, typename U> virtual bool EpetraExt::Transform< T, U >::fwd (   )  [pure virtual]

Forward transfer of data from orig object input in the operator() method call to the new object created in this same call. Returns true is operation is successful. Preconditions: Invariants: Postconditions:

template<typename T, typename U> bool EpetraExt::Transform< T, U >::isConstructed (   )  [virtual]

Check for whether transformed object has been constructed Preconditions: Invariants: Postconditions: The default implementation returns true if newObj_ != 0.

template<typename T, typename U> virtual NewTypeRef EpetraExt::Transform< T, U >::operator() (  OriginalTypeRef  orig  )  [pure virtual]

Analysis of transform operation on original object and construction of new object. Preconditions: Invariants: Postconditions: Returns: Returns a pointer to the newly created object of type NewTypeRef. The Transform object maintains ownership of this new object and deletes as a part of it's destruction.

template<typename T, typename U> virtual bool EpetraExt::Transform< T, U >::rvs (   )  [pure virtual]

Reverse transfer of data from new object created in the operator() method call to the orig object input to this same method. Returns true if operation is successful. Preconditions: Invariants: Postconditions:
