Object Synopsis

column -- object representing a column of data in a Merlin pool


A Column object represents a "column" of data from a Merlin pool, i.e. one specific field from each TDT in the database. A column is the "y axis" of the "spreadsheet" view of the database.

A column object is defined by three properties: The pool (database) which is the column's parent object; the fieldtype object that specifies the datatype and which field within that datatype is to be used in the column; and the "function" that how to select from among multiple instances of the field in one TDT.
