Detailed Description

Concrete subclass for a default sub-view implementation for a Vector object.

Not all of the methods from Vector are overridden, only those that need to be or may result in better performance.

There is really not much to this vector subclass. The subclass is only possible because of the first_ele, sub_dim, and global_offset options with apply_op(). The vector space object returned by this->space() is of type VectorSpaceSubSpace which in turn relys on VectorSpace::sub_space().

The default constructor and copy constructors are allowed but the default assignment operator is not allowed.

Member Function Documentation

void AbstractLinAlgPack::VectorSubView::initialize	(	const vec_ptr_t &	full_vec,
		const Range1D &	rng
	)

Initialize a sub-view based on a full vector.

Constructs a view of the vector this = vec(rng).

Preconditions:

full_vec.get() != NULL (throw std::invalid_argument)
[rng.full_range() == false] rng.lbound() <= full_vec->dim() (throw std::out_of_range).

Postconditions:

this->get_ele(i) == full_vec->get_ele(rng.lbound()-1+i), for i = 1...rng.size()

Parameters

full_vec	[in] The original full vector.
rng	[in] The range of elements in `full_vec` that `this` vector will represent.

Postconditions:

this->dim() == 0
this->full_vec() = NULL
