Class SortedEntrySerializer

java.lang.Object

org.apache.directory.server.core.shared.SortedEntrySerializer

All Implemented Interfaces:

java.io.Serializable, jdbm.helper.Serializer

public class SortedEntrySerializer
extends java.lang.Object
implements jdbm.helper.Serializer

Serialize and deserialize a ServerEntry. WARNING: This serializer stores the complete DN as well (unlike other entry serializers which store only RDN). This class must *not* be used anywhere else other than for storing sorted entries in server. Note: this was initially used by Mavibot tree, but changed to use in JDBM later. This will again be ported to Mavibot as soon as it gets ready.

Method Detail

serialize

public byte[] serialize(java.lang.Object obj)
                 throws java.io.IOException

Specified by:

serialize in interface jdbm.helper.Serializer

Throws:

java.io.IOException

deserialize

public java.lang.Object deserialize(byte[] serialized)
                             throws java.io.IOException

Specified by:

deserialize in interface jdbm.helper.Serializer

Throws:

java.io.IOException

serialize

public byte[] serialize(org.apache.directory.api.ldap.model.entry.Entry entry)

This is the place where we serialize entries, and all theirs elements. the reason why we don't call the underlying methods (ServerAttribute.write(), Value.write()) is that we need access to the registries to read back the values.

The structure used to store the entry is the following :

• [Dn] : The entry's Rdn.
• [numberAttr] : the bumber of attributes. Can be 0
• For each Attribute :
  • [attribute's oid] : The attribute's OID to get back the attributeType on deserialization
  • [Attribute] The attribute

setSchemaManager

public static void setSchemaManager(org.apache.directory.api.ldap.model.schema.SchemaManager schemaManager)
