org.pentaho.reporting.libraries.formula.lvalues.FormulaFunction
A function. Formulas consist of functions, references or static values, which are connected by operators.
Functions always have a cannonical name, which must be unique and which identifies the function. Functions can have a list of parameters. The number of parameters can vary, and not all parameters need to be filled.
Functions can have required and optional parameters. Mixing required and optional parameters is not allowed. Optional parameters cannot be ommited, unless they are the last parameter in the list.
This class provides the necessary wrapper functionality to fill in the parameters. @author Thomas Morgner
