Class AttributeType

  • All Implemented Interfaces:
    Comparable<AttributeType>, SchemaElement
    public final class AttributeType
extends Object
implements Comparable<AttributeType>
    This class defines a data structure for storing and interacting with an attribute type, which contains information about the format of an attribute and the syntax and matching rules that should be used when interacting with it.

    Where ordered sets of names, or extra properties are provided, the ordering will be preserved when the associated fields are accessed via their getters or via the Object.toString() methods.

    • Method Detail

      • compareTo

        public int compareTo​(AttributeType type)
        Compares this attribute type to the provided attribute type. The sort-order is defined as follows:
        • The objectClass attribute is less than all other attribute types.
        • User attributes are less than operational attributes.
        • Lexicographic comparison of the primary name and then, if equal, the OID.
        Specified by:
        compareTo in interface Comparable<AttributeType>
        Parameters:
        type - The attribute type to be compared.
        Returns:
        A negative integer, zero, or a positive integer as this attribute type is less than, equal to, or greater than the specified attribute type.
