Package javax0.license3j

Class Feature

  • public class Feature
extends java.lang.Object
    A feature is a single "feature" in a license. It has a
    • name,
    • a type
    • and a value.
    The type can be one of the types that are defined in the enumeration Feature.Type.

    There is a utility class inside this class called Feature.Create that contains public static methods to create features for each type. Invoking one of those methods is the way to create a new feature instance.

    A feature can be tested against the type calling one of the boolean methods isXXX(), where XXX is one of the types. Getting the value from a type should be via the methods getXXX, where, again, XXX is one of the types. Invoking getXXX for a feature that has a type that is not XXX will throw IllegalArgumentException.

    Features can be serialized to a byte array invoking the method serialized(). The same byte array can be used as an argument to the utility method Feature.Create.from(byte[]) to create a Feature of the same name and the same value.

    • Method Detail

      • name

        public java.lang.String name()
        Returns:
        the name of the feature.

      • toString

        public java.lang.String toString()
        Overrides:
        toString in class java.lang.Object

      • valueString

        public java.lang.String valueString()
        Returns:
        the string representation of the value of the feature.

      • serialized

        public byte[] serialized()
        Convert a feature to byte array. The bytes will have the following structure 
              [4-byte type][4-byte name length][4-byte value length][name][value]
        or 
              [4-byte type][4-byte name length][name][value]
        if the length of the value can be determined from the type (some types have fixed length values).
        Returns:
        the byte array representation of the feature
