Detailed Description

Provide access to a particular chunk of a chunked vector.

A chunked vector has multiple types of information encoded within a single vector, with a layout like [x_1, x_2, ..., x_n, y_1, y_2, ... y_n]. This class provides easy access to, for example, the x values.

Member Function Documentation

double& DistributedVector::Chunk::operator[] ( Iterator index ) throw (DistributedVectorException) [inline]

Parameters:

index

Returns:: value of striped distributed vector pointed to by index.

References mOffset, and mpVec.

double& DistributedVector::Chunk::operator[] ( unsigned globalIndex ) throw (DistributedVectorException) [inline]

Access a particular element of the chunk if on this processor. For use in tests. Will throw a DistributedVectorException if the specified element is not on this process.

Parameters:

globalIndex

index within the chunk
