      • LDAPCompareAttrNames

        public LDAPCompareAttrNames​(java.lang.String attribute)
        Constructs a comparator that compares the string values of a named attribute in LDAP entries and sorts the entries in ascending order.

        Parameters:
        attribute - name of attribute for comparisons
      • LDAPCompareAttrNames

        public LDAPCompareAttrNames​(java.lang.String attribute,
                                    boolean ascendingFlag)
        Constructs a comparator that compares the string values of a named attribute in LDAP entries and that allows you to sort entries either in ascending or descending order.

        Parameters:
        attribute - name of attribute for comparisons
        ascendingFlag - if true, sort in ascending order
      • LDAPCompareAttrNames

        public LDAPCompareAttrNames​(java.lang.String[] attributes)
        Constructs a comparator that compares the string values of a set of named attributes in LDAP entries and that sort the entries in ascending order.

        Use an array of strings to specify the set of attributes to use for sorting. If the values of the first attribute (the name specified in attribute[0]) are equal, then the values of the next attribute are compared.

        For example, if attributes[0] = "cn" and attributes[1]="uid", results are first sorted by the cn attribute. If two entries have the same value for cn, then the uid attribute is used to sort the entries.

        Parameters:
        attributes - array of the attribute names used for comparisons
      • LDAPCompareAttrNames

        public LDAPCompareAttrNames​(java.lang.String[] attributes,
                                    boolean[] ascendingFlags)
        Constructs a comparator that compares the string values of a set of named attributes in LDAP entries and allows you to sort the entries in ascending or descending order.

        Use an array of strings to specify the set of attributes to use for sorting. If the values of the first attribute (the name specified in attribute[0]) are equal, then the values of the next attribute are compared.

        For example, if attributes[0] = "cn" and attributes[1]="uid", results are first sorted by the cn attribute. If two entries have the same value for cn, then the uid attribute is used to sort the entries.

        Use an array of boolean values to specify whether each attribute should be sorted in ascending or descending order. For example, suppose that attributes[0] = "cn" and attributes[1]="roomNumber". If ascendingFlags[0]=true and ascendingFlags[1]=false, attributes are sorted first by cn in ascending order, then by roomNumber in descending order.

        If the size of the array of attribute names is not the same as the size of the array of boolean values, an LDAPException is thrown.

        Parameters:
        attributes - array of the attribute names to use for comparisons
        ascendingFlags - array of boolean values specifying ascending or descending order to use for each attribute name. If true, the attributes are sorted in ascending order.
    • Method Detail

      • getLocale

        public java.util.Locale getLocale()
        Gets the locale, if any, used for collation. If the locale is null, an ordinary string comparison is used for sorting.
        Returns:
        the locale used for collation, or null.
      • setLocale

        public void setLocale​(java.util.Locale locale)
        Set the locale, if any, used for collation. If the locale is null, an ordinary string comparison is used for sorting. If sorting has been set to case-insensitive, the collation strength is set to Collator.PRIMARY, otherwise to Collator.IDENTICAL. If a different collation strength setting is required, use the signature that takes a collation strength parameter.
        Parameters:
        locale - the locale used for collation, or null.
      • setLocale

        public void setLocale​(java.util.Locale locale,
                              int strength)
        Sets the locale, if any, used for collation. If the locale is null, an ordinary string comparison is used for sorting.
        Parameters:
        locale - the locale used for collation, or null.
        strength - collation strength: Collator.PRIMARY, Collator.SECONDARY, Collator.TERTIARY, or Collator.IDENTICAL
      • getCaseSensitive

        public boolean getCaseSensitive()
        Gets the state of the case-sensitivity flag. This only applies to Unicode sort order; for locale-specific sorting, case-sensitivity is controlled by the collation strength.
        Returns:
        true for case-sensitive sorting; this is the default
      • setCaseSensitive

        public void setCaseSensitive​(boolean sensitive)
        Sets the state of the case-sensitivity flag. This only applies to Unicode sort order; for locale-specific sorting, case-sensitivity is controlled by the collation strength.
        Parameters:
        sensitive - true for case-sensitive sorting; this is the default
      • isGreater

        public boolean isGreater​(LDAPEntry greater,
                                 LDAPEntry less)
        Returns true if the value of the attribute in the first entry is greater than the value of the attribute in the second entry.

        If one of the entries is missing the attribute, the other is considered greater. By default, the first entry is greater.

        If either entry contains multiple values, only the first value is used for comparisons.

        Specified by:
        isGreater in interface LDAPEntryComparator
        Parameters:
        greater - entry against which to test
        less - entry to test
        Returns:
        true if (greater > less).
