class | Iterator |
Accessor class for iterators into objects of type DynamicSparsityPattern.
Note that this class only allows read access to elements, providing their row and column number (or alternatively the index within the complete sparsity pattern). It does not allow modifying the sparsity pattern itself.

Constructor. Construct the end accessor for the given sparsity pattern.
Definition at line 782 of file dynamic_sparsity_pattern.h.
|
inline |
Default constructor creating a dummy accessor. This constructor is here only to be able to store accessors in STL containers such as std::vector
.

Row number of the element represented by this object.

Index within the current row of the element represented by this object.

inline |
Column number of the element represented by this object.

Comparison. True, if both iterators point to the same matrix position.
Definition at line 836 of file dynamic_sparsity_pattern.h.
Comparison operator. Result is true if either the first row number is smaller or if the row numbers are equal and the first index is smaller.
This function is only valid if both iterators point into the same sparsity pattern.

The sparsity pattern we operate on accessed.

The row we currently point into.

A pointer to the element within the current row that we currently point to.
Definition at line 143 of file dynamic_sparsity_pattern.h.

protected |
A pointer to the end of the current row. We store this to make comparison against the end of line iterator cheaper as it otherwise needs to do the IndexSet translation from row index to the index within the 'lines' array of DynamicSparsityPattern.
