Usage

From source file:org.springframework.ldap.core.DirContextAdapter.java

/**
 * Collect all modifications for the changed attribute. If no changes have
 * been made, return immediately. If modifications have been made, and the
 * original size as well as the updated size of the attribute is 1, replace
 * the attribute. If the size of the updated attribute is 0, remove the
 * attribute. Otherwise, the attribute is a multi-value attribute; if it's
 * an ordered one it should be replaced in its entirety to preserve the new
 * ordering, if not all modifications to the original value (removals and
 * additions) will be collected individually.
 * /*from   w w w.j  a v a  2 s  .c om*/
 * @param changedAttr the value of the changed attribute.
 * @param modificationList the list in which to add the modifications.
 * @throws NamingException if thrown by called Attribute methods.
