Class NumberValidator<T extends Number & Comparable<T>>

java.lang.Object
org.moeaframework.util.validate.Validator<T>
org.moeaframework.util.validate.NumberValidator<T>
Type Parameters:
T - the number type
Direct Known Subclasses:
DoubleValidator, IntegerValidator
public abstract class NumberValidator<T extends Number & Comparable<T>> extends Validator<T>
Abstract validator for Numbers.

To simplify the implementation of these validations, we use the fact that most numeric types implement the Comparable interface. Consequently, this class only supports the "boxed" types for numbers, while most parameters we are validating are primitives. Thus, prefer creating subclasses that accept only the primitive type, which then call these generic methods.

    • isNotEqualTo

      protected final void isNotEqualTo(String parameterName, T parameterValue)
      Asserts the value is not equal to some other parameter.
      Parameters:
      parameterName - the parameter name, or null if not associated with a named parameter
      parameterValue - the parameter value

    • isBetween

      protected final void isBetween(T lower, T upper)
      Asserts the value is between the given lower and upper bounds, inclusive.
      Parameters:
      lower - the lower bound
