SCHEMA_MODIFIED, SCHEMA_UNCHANGED

Constructor Summary

SchemaSynchronizer(org.apache.directory.shared.ldap.schema.SchemaManager schemaManager)
Creates and initializes a new instance of Schema synchronizer

Method Summary

void	add(org.apache.directory.shared.ldap.entry.ServerEntry entry) Handles the addition of a metaSchema object to the schema partition.
void	delete(org.apache.directory.shared.ldap.entry.ServerEntry entry, boolean cascade) Called to react to the deletion of a metaSchema object.
boolean	modify(ModifyOperationContext opContext, org.apache.directory.shared.ldap.entry.ServerEntry targetEntry, boolean cascade) 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.
void	move(org.apache.directory.shared.ldap.name.DN oriChildName, org.apache.directory.shared.ldap.name.DN newParentName, org.apache.directory.shared.ldap.entry.ServerEntry entry, boolean cascade) Moves are not allowed for metaSchema objects so this always throws an UNWILLING_TO_PERFORM LdapException.
void	moveAndRename(org.apache.directory.shared.ldap.name.DN oriChildName, org.apache.directory.shared.ldap.name.DN newParentName, org.apache.directory.shared.ldap.name.RDN newRn, boolean deleteOldRn, org.apache.directory.shared.ldap.entry.ServerEntry entry, boolean cascaded)

void	rename(org.apache.directory.shared.ldap.entry.ServerEntry entry, org.apache.directory.shared.ldap.name.RDN newRdn, boolean cascade) Responds to the rdn (commonName) of the metaSchema object being changed.

Method Detail

modify

public boolean modify(ModifyOperationContext opContext,
                      org.apache.directory.shared.ldap.entry.ServerEntry targetEntry,
                      boolean cascade)
               throws java.lang.Exception

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.

targetEntry - The modified entry

cascade - Unused

Returns:

True if the modification has been done

Throws:

moveAndRename

public void moveAndRename(org.apache.directory.shared.ldap.name.DN oriChildName,
