Interface ParameterizedExpression

All Known Subinterfaces:
ElementExpression
@OpenApiAll public interface ParameterizedExpression
Expression calculates the value according given parameter values (arguments).
Actual implementation must declare the public method getValue with custom number of parameters, plus additional last parameter of ValueContext type.
E.g. 
     public class ParameterizedExpressionImpl implements ParameterizedExpression
     {
        /**
          * Value calculation method.
          *
          * @param parameter1   parameter of String type.
          * @param parameter2   parameter of boolean type.
          * @param valueContext context mandatory parameter.
          * @return calculated value.
         */
         public Object getValue(String parameter1, boolean parameter2, ValueContext valueContext)
         {
             // value context is ignored in this implementation
             // construct string using passed arguments
             return "String: " + parameter1 + " boolean: " + parameter2;
         }
     }

    • getResultType

      @CheckForNull Class<?> getResultType()
      Returns type of the result. Null means that result type is unknown. If the expression returns a collection of objects then the implementation should return a class of single object.
      Returns:
      result type.
