template<typename T >

Constructor. Creates a EpetraVector assuming you already have a valid Epetra Vec object. In this case, v is NOT destroyed by the EpetraVector constructor when this object goes out of scope. This allows ownership of v to remain with the original creator, and to simply provide additional functionality with the EpetraVector.

Change the dimension of the vector to n. The reserved memory for this vector remains unchanged if possible. If n==0, all memory is freed. Therefore, if you want to resize the vector and release the memory not needed, you have to first call init(0) and then init(n). This behaviour is analogous to that of the STL containers.

On fast==false, the vector is filled by zeros.

overridevirtual

Fill in the local std::vector "v_local" with the global indices given in "indices".

Note: The indices can be different on every processor, and the same index can be localized to more than one processor. The resulting v_local can be shorter than the original, and the entries will be in the order specified by indices.

Example:

*   On 4 procs *this = {a, b, c, d, e, f, g, h, i} is a parallel vector.
*   On each proc, the indices arrays are set up as:
*   proc0, indices = {1,2,4,5}
*   proc1, indices = {2,5,6,8}
*   proc2, indices = {2,3,6,7}
*   proc3, indices = {0,1,2,3}
*
*   After calling this version of localize, the v_local vectors are:
*   proc0, v_local = {b,c,e,f}
*   proc1, v_local = {c,f,g,i}
*   proc2, v_local = {c,d,g,h}
*   proc3, v_local = {a,b,c,d}
*

This function is useful in parallel I/O routines, when you have a parallel vector of solution values which you want to write a subset of.

Returns: A smart pointer to a copy of this vector with the same type, size, and partitioning, but with all zero entries.

Note: This must be overridden in the derived classes.

Implements libMesh::NumericVector< T >.
