Method Detail

modify

public boolean modify(ModifyOperationContext modifyContext,
                      org.apache.directory.api.ldap.model.entry.Entry targetEntry,
                      boolean cascade)
               throws org.apache.directory.api.ldap.model.exception.LdapException

The only modification done on a schema element is on the m-disabled attributeType Depending in the existence of this attribute in the previous entry, we will have to update the entry or not.

Specified by:

modify in interface RegistrySynchronizer

Parameters:

modifyContext - The OperationContext, which contains the entry and the modifications to apply

targetEntry - The modified entry

cascade - Unused

Returns:

True if the modification has been done

Throws:

org.apache.directory.api.ldap.model.exception.LdapException

moveAndRename

public void moveAndRename(org.apache.directory.api.ldap.model.name.Dn oriChildName,
                          org.apache.directory.api.ldap.model.name.Dn newParentName,
                          org.apache.directory.api.ldap.model.name.Rdn newRn,
                          boolean deleteOldRn,
                          org.apache.directory.api.ldap.model.entry.Entry entry,
                          boolean cascaded)
                   throws org.apache.directory.api.ldap.model.exception.LdapException

Specified by:

moveAndRename in interface RegistrySynchronizer

Throws:

org.apache.directory.api.ldap.model.exception.LdapException

add

public void add(org.apache.directory.api.ldap.model.entry.Entry entry)
         throws org.apache.directory.api.ldap.model.exception.LdapException

Handles the addition of a metaSchema object to the schema partition.

Specified by:

add in interface RegistrySynchronizer

Parameters:

name - the dn of the new metaSchema object

entry - the attributes of the new metaSchema object

Throws:

org.apache.directory.api.ldap.model.exception.LdapException

delete

public void delete(org.apache.directory.api.ldap.model.entry.Entry entry,
                   boolean cascade)
            throws org.apache.directory.api.ldap.model.exception.LdapException

Called to react to the deletion of a metaSchema object. This method simply removes the schema from the loaded schema map of the global registries.

Specified by:

delete in interface RegistrySynchronizer

Parameters:

name - the dn of the metaSchema object being deleted

entry - the attributes of the metaSchema object

Throws:

org.apache.directory.api.ldap.model.exception.LdapException

rename

public void rename(org.apache.directory.api.ldap.model.entry.Entry entry,

                   boolean cascade)
            throws org.apache.directory.api.ldap.model.exception.LdapException

Responds to the rdn (commonName) of the metaSchema object being changed. Changes all the schema entities associated with the renamed schema so they now map to a new schema name.

Specified by:

rename in interface RegistrySynchronizer

Parameters:

name - the dn of the metaSchema object renamed

entry - the entry of the metaSchema object before the rename

newRdn - the new commonName of the metaSchema object

Throws:

org.apache.directory.api.ldap.model.exception.LdapException

moveAndRename

public void moveAndRename(org.apache.directory.api.ldap.model.name.Dn oriChildName,
                          org.apache.directory.api.ldap.model.name.Dn newParentName,
                          String newRn,

                   throws org.apache.directory.api.ldap.model.exception.LdapUnwillingToPerformException
