Examples of jimm.datavision.Formula

jimm.datavision.Formula
A formula is a Bean Scripting Framework (BSF) script evaluated at runtime. It may contain database column values, other formulas, special values, and aggregates.
Before being evaluated, the following substitutions are made withing the evaluation string of a formula:
- {table_name.column_name} is replaced by the current value of the column table_name.column_name, but only if the column exists. If it doesn't, then the entire "{...}" text is kept as-is.
- {@id_number} is replaced by the results of evaluating the formula whose id is id_number.
- {%special_value_name} is replaced by a special value (report title, report run date, page number, or record number).
- {?id_number} is replaced by a parameter value (string, number, or date).
- {!id_number} is replaced by a user column's value (string, number, or date).
