Multidimensional View Expressions

Collaboration diagram for Multidimensional View Expressions:

Description

Implementing view modifier chain as combination of command pattern and chain of responsibility pattern. For now, only compile-time projections/slices are supported such as:

sub<0>(10,20).sub<1>(30,40)

but not run-time projections/slices like:

sub(0, { 10,20 }).sub(1, { 30,40 })

Implementation Notes

A view composition is a chained application of view modifier types that depend on the type of their predecessor in the chain.

Example:

sub<0>(2).sub<1>(3,4)
:         :
|         |
|         '--> ViewSubMod<0, ViewSubMod<-1, ViewOrigin> >
|                            '------------.-----------'
|                                         '--> parent
'--> ViewSubMod<-1, ViewOrigin >
                    '----.---'
                         '--> parent

Consequently, specific ViewMod types are defined for every modifier category.
