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.

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 looks like a copy assignment operator, but note that, unlike normal copy assignment operators, it is pure virtual.

This function should be overridden in derived classes so that they can be copied correctly via references to the base class.
