Enum DataType

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<DataType>
    public enum DataType
extends java.lang.Enum<DataType>
    Enum definition for data primitives in the context of serialisation and includes definitions for:
    • primitives (byte, short, ..., float, double, and String), and
    • arrays thereof (ie. byte[], short[], ..., float[], double[], and String[]), as well as
    • complex objects implementing Collections (ie. Set, List, Queues), Enums or Maps.
    Any other complex data objects can be stored/extended using the OTHER sub-type.

    N.B. Multi-dimensional arrays are handled through one-dimensional striding arrays with the additional infos on number of dimensions and size for each individual dimension.

      • values

        public static DataType[] 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 (DataType c : DataType.values())
    System.out.println(c);
        Returns:
        an array containing the constants of this enum type, in the order they are declared

      • valueOf

        public static DataType valueOf​(java.lang.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:
        java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
        java.lang.NullPointerException - if the argument is null

      • getID

        public int getID()
        Returns the uniqueID representation of the data type.
        Returns:
        the uniqueID representation

      • getAsString

        public java.lang.String getAsString()
        Returns the string representation of the data type.
        Returns:
        the string representation

      • getClassTypes

        public java.util.List<java.lang.Class<?>> getClassTypes()
        Returns the corresponding java class type matching the given data type
        Returns:
        the matching java class type

      • getJavaName

        public java.lang.String getJavaName()
        Returns the string representation of the java class type.
        Returns:
        the string representation of the class
