Virtual column forwarding to another row/column

Prerequisite

Etymology

ForwardColumnIndexedRow handles the forwarding of the gets and puts for an individual row/column on behalf of the virtual column engine ForwardColumnIndexedRowEngine. It forwards them to a row/column in another table. The row forwarding is done using a special column containing row numbers indexing the referenced table.

Synopsis

ForwardColumnIndexedRow represents a virtual column which forwards the gets and puts to a column with the same name in another table. It is, in fact, a reference to the other column. The row numbers in the column are mapped to row numbers in the referenced column using a special column containing the mapping. The name of the other table is stored as a keyword in the forwarding column. When the referenced column is in its turn a ForwardColumn (note: not a ForwardColumnIndexedRow), the table mentioned in there will be used. In this way, the length of the forwarding chain is kept to a minimum.

An object of this class is created (and deleted) by the virtual column engine

ForwardColumnIndexedRowEngine which creates a ForwardColumnIndexedRow object for each column being forwarded.
