void jive::solver::CoarseDofSpace::update ( )

bool jive::solver::CoarseDofSpace::updated ( ) const

virtual idx_t jive::solver::CoarseDofSpace::typeCount ( ) const

virtual

Returns the number of dof types known to this dof space.

Returns: The number of dof types.

Implements jive::util::DofSpace.

virtual idx_t jive::solver::CoarseDofSpace::dofCount ( ) const

virtual

Returns the number of dofs known to this dof space. This number is equal to the number of non-zeroes in the sparse matrix representation of this dof space.

Note that the number of dofs equals

itemCount() * typeCount()

when the matrix representation of this dof space is a dense matrix. That is, when typeCount() dofs are attached to each item.

Returns: The number of dofs.

Implements jive::util::DofSpace.

idx_t jive::solver::CoarseDofSpace::globalDofCount ( ) const

virtual void jive::solver::CoarseDofSpace::resetEvents ( )

virtual

virtual idx_t jive::solver::CoarseDofSpace::findType ( const String & name ) const

virtual

Returns the index of the dof type named name, or a negative number if a dof type with that name is not known to this dof space.

The implementation of this function provided by the DofSpace class searches for the type index by repeatedly calling the getTypeName() function. Derived classes are encouraged to provide a more efficient implementation.

Parameters

name	- the name of the dof type to be found.

return The index of the dof type named name, or a negative number.

Reimplemented from jive::util::DofSpace.

virtual String jive::solver::CoarseDofSpace::getTypeName ( idx_t itype ) const

virtual

virtual StringVector jive::solver::CoarseDofSpace::getTypeNames ( ) const

virtual

Returns an array containing the names of all dof types known to this dof space. The contents of this array should not be modified as the array may share its data with one of the private data members of this DofSpace object.

The implementation of this function provided by the DofSpace class creates the array by repeatedly calling the getTypeName() function.

Returns: An array containing all dof type names.

Reimplemented from jive::util::DofSpace.

	)		const

virtual

virtual SparseIdxMatrix jive::solver::CoarseDofSpace::toMatrix ( ) const

virtual

Returns a sparse matrix representation of this dof space. Each row in the matrix is associated with an item and each column is associated with a dof type. The value of a matrix element (i,j) is the global index, or equation number, of the dof that is attached to item i and has type j.

Returns: A sparse matrix representation of this dof space.

Implements jive::util::DofSpace.

virtual ItemSet* jive::solver::CoarseDofSpace::getItems ( ) const

virtual

Returns a pointer to the item set containing the items to which the dofs in this dof space are attached. The pointer is guaranteed not to be NULL and to remain valid throughout the entire lifetime of this DofSpace object.

Returns: A pointer to the item set associated with this dof space.

Implements jive::util::DofSpace.
