Class DirRecord

  • All Implemented Interfaces:
    Serializable
    Direct Known Subclasses:
    BasicDirRecord

    public abstract class DirRecord
    extends Object
    implements Serializable
    This class represents a directory record which may be built from a number of attributes, retrieved as a search result or read from some input stream.

    We will implement some aspects of the ldif as defined in RFC 2849 within this class. These will be related to the content vs change records. By default, a DirRecord object will be a content record. However, we will allow the creation of change type records. Having this defined here allows applications to pass around DirRecord objects without any idea of the underlying implementation.

    Currently the following is implemented:

    • content records Consist of a dn with an associated set of attributes with values. No attribute options are implemented. Encoded strings may be converted incorrectly (need to check locale specifics)
    • change records.
      • add: Implemented. Look just like content records.
      • delete: Implemented. Consist of a dn only.
      • all others are unimplemented.

      • setAttr

        public void setAttr​(String attr,
                            Object val)
                     throws NamingException
        Set the attribute value in the table. Replaces any existing value(s) This does not write back to the directory
        Parameters:
        attr -
        val -
        Throws:
        NamingException
      • clear

        public void clear()
        Should be overriden to clear attributes.
      • equals

        public boolean equals​(DirRecord that,
                              String[] thisAttrIDs,
                              String[] thatAttrIDs)
                       throws NamingException
        Compare this with that only looking at the named attributes. For this method, the dns must be equal and the values of the named attributes must be equal but their names may differ. The two arrays of attrIDs must be non-null and of the same length or an exception is raised. If there are no attributes in both records they are considered equal. If there are no attributes in only one record they are unequal. Zero length attrID lists means only the dn is compared.
        Parameters:
        that -
        thisAttrIDs -
        thatAttrIDs -
        Returns:
        boolean
        Throws:
        NamingException
      • equals

        public boolean equals​(DirRecord that,

                       throws NamingException
        Simpler form of equals in which attributes have the same names in both records.
        Parameters:
        that -
        attrIDs -
        Returns:
        boolean
        Throws:
        NamingException
      • equalsAllBut

        public boolean equalsAllBut​(DirRecord that,
                                    String[] attrIDs)
                             throws NamingException
        This compares all but the named attributes allbut true => All must be equal except those on the list
        Parameters:
        that -
        attrIDs -
        Returns:
        boolean
        Throws:
        NamingException

If the attribute values are ordered, the enumeration's items will be ordered. Each element of the enumeration is a possibly null Object. The object's class is the class of the attribute value. The element is null if the attribute's value is null. If the attribute has zero values, an empty enumeration is returned.
        Returns:
        A non-null enumeration of the attribute's values.
        Throws:
        NamingException - If a naming exception was encountered while retrieving the values.
