From source file:ddf.catalog.validation.impl.validator.RangeValidator.java

/**
 * Creates a {@code RangeValidator} with an <strong>inclusive</strong> range and the provided
 * epsilon.//from w ww.  j a v a  2 s .c om
 * <p>
 * Uses the provided epsilon on both sides of the range to account for floating point
 * representation inaccuracies, so the range is really [min - epsilon, max + epsilon].
 *
 * @param min     the minimum allowable value (inclusive), cannot be null
 * @param max     the maximum allowable value (inclusive), cannot be null and must be greater
 *                than {@code min}
 * @param epsilon the epsilon value, cannot be null and must be positive
 * @throws IllegalArgumentException if {@code max} is not greater than {@code min},
 *                                  {@code epsilon} is not positive, or if any argument is null
