FunctionArgument

public final class FunctionCondition
extends Condition

A Condition that represents a condition that evaluates a FunctionArgument that produces a Boolean value. For example, the following code creates a FunctionCondition for the LNNVL function.

  NumberExpression rhsArg = new NumberExpression(.2);
  StringExpression lhsArg = new StringExpression("commission_pct");
  ValueComparisonCondition funcArg = 
        new ValueComparisonCondition(lhsArg, 
                                     ValueComparisonCondition.LT, 
                                     rhsArg); 
  FunctionCondition fc = new FunctionCondition("LNNVL", funcArg);

The toSyntax method of the fc object returns a String that contains the following:

 LNNVL('commission_pct' < 0.2)

You can create the same FunctionCondition by using the SyntaxObject.fromSyntax method, as in the following, where metadataProvider is an MdmMetadataProvider:

 FunctionCondition fc = (FunctionCondition) 
                        SyntaxObject.fromSyntax("LNNVL('commission_pct' < .2)", 
                                                 metadataProvider);
