Enum Contains

  • All Implemented Interfaces:
    Serializable, Comparable<Contains>, BiPredicate<Object,​Collection>, PBiPredicate<Object,​Collection>

    public enum Contains
    extends Enum<Contains>
    implements PBiPredicate<Object,​Collection>
    Contains is a BiPredicate that evaluates whether the first object is contained within (or not within) the second collection object. If the first object is a number, each element in the second collection will be compared to the first object using Compare's eq predicate. This will ensure, that numbers are matched by their value only, ignoring the number type. For example:

     gremlin Contains.within [gremlin, blueprints, furnace] == true
     gremlin Contains.without [gremlin, rexster] == false
     rexster Contains.without [gremlin, blueprints, furnace] == true
     123 Contains.within [1, 2, 3] == false
     100 Contains.within [1L, 10L, 100L] == true

      • values

        public static Contains[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
        for (Contains c : Contains.values())
            System.out.println(c);
        
        Returns:
        an array containing the constants of this enum type, in the order they are declared
      • valueOf

        public static Contains valueOf​(String name)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
        Parameters:
        name - the name of the enum constant to be returned.
        Returns:
        the enum constant with the specified name
        Throws:
        IllegalArgumentException - if this enum type has no constant with the specified name
        NullPointerException - if the argument is null
