    • Method Detail

      • addAttribute

        default boolean addAttribute​(Attribute attribute)
        Ensures that this entry contains the provided attribute and values (optional operation). This method has the following semantics:
        • If this entry does not already contain an attribute with a matching attribute description, then this entry will be modified such that it contains attribute, even if it is empty.
        • If this entry already contains an attribute with a matching attribute description, then the attribute values contained in attribute will be merged with the existing attribute values.

        NOTE: When attribute is non-empty, this method implements LDAP Modify add semantics.

        Parameters:
        attribute - The attribute values to be added to this entry, merging with any existing attribute values.
        Returns:
        true if this entry changed as a result of this call.
        Throws:
        UnsupportedOperationException - If this entry does not permit attributes or their values to be added.
        NullPointerException - If attribute was null.

                             Collection<? super ByteString> duplicateValues)
        Ensures that this entry contains the provided attribute and values (optional operation). This method has the following semantics:
        • If this entry does not already contain an attribute with a matching attribute description, then this entry will be modified such that it contains attribute, even if it is empty.
        • If this entry already contains an attribute with a matching attribute description, then the attribute values contained in attribute will be merged with the existing attribute values.

        NOTE: When attribute is non-empty, this method implements LDAP Modify add semantics.

        Parameters:
        attribute - The attribute values to be added to this entry, merging with any existing attribute values.
        duplicateValues - A collection into which duplicate values will be added, or null if duplicate values should not be saved.
        Returns:
        true if this entry changed as a result of this call.
        Throws:
        UnsupportedOperationException - If this entry does not permit attributes or their values to be added.
        NullPointerException - If attribute was null.

      • addAttribute

                           Object... values)
        Ensures that this entry contains the provided attribute and values (optional operation). This method has the following semantics:
        • If this entry does not already contain an attribute with a matching attribute description, then this entry will be modified such that it contains attribute, even if it is empty.
        • If this entry already contains an attribute with a matching attribute description, then the attribute values contained in attribute will be merged with the existing attribute values.

        Returns true if this entry contains any non-empty attributes having an attribute description which is a sub-type of the provided attribute description.

        NOTE: this method performs the matching defined for an LDAP search presence filter. For example, given the attribute description "name" then this method will return true if the entry contains "name", "name;option", "cn", or "cn;option". This method is NOT suitable for schema checking, which uses different matching semantics. Specifically, an entry which MUST contain "name" is not valid if it contains "cn", but not "name".
