Filter is a general postprocessing class, intended for visualization. The output of Filter is an arbitrary combination of up to three input functions, which usually are Solutions to PDEs, but can also be other Filters.
(This class cannot be instantiated.)

protectedvirtual |
Removes the current transformation matrix from the top of the stack. The new top becomes the current transformation matrix. This returns the transform to the state before the last push_transform() was performed.

Called by the assembling procedure and by other functions. In PrecalcShapeset it sets an internal variable that can be later retrieved by get_active_element(). In Solution it selects the element to retrieve solution values for, etc.

protectedvirtual |
Selects the quadrature points in which the function will be evaluated.
It is possible to switch back and forth between different quadrature points: no precalculated values are freed. The standard quadrature is always selected by default already.

There is a 2-layer structure of the precalculated tables. The first (the lowest) one is the layer where mapping of integral orders to Function::Node takes place. See function.h for details. The second one is the layer with mapping of sub-element transformation to a table from the lowest layer. The highest layer (in contrast to the PrecalcShapeset class) is represented here only by this array.
