Constructor Detail

ImmutableNameFormRegistry

public ImmutableNameFormRegistry(NameFormRegistry nameFormRegistry)

Creates a new instance of ImmutableNameFormRegistry.

Parameters:

nameFormRegistry - The wrapped NameForm registry

Method Detail

copy

public ImmutableNameFormRegistry copy()

Copy the NameFormRegistry

Specified by:

copy in interface NameFormRegistry

Specified by:

copy in interface SchemaObjectRegistry<NameForm>

Returns:

SchemaObjectRegistry The copied registry

size

public int size()

Specified by:

size in interface SchemaObjectRegistry<NameForm>

Returns:

The number of AttributeType stored

contains

public boolean contains(String oid)

Checks to see if an SchemaObject exists in the registry, by its OID or name.

Specified by:

contains in interface SchemaObjectRegistry<NameForm>

Parameters:

oid - the object identifier or name of the SchemaObject

Returns:

true if a SchemaObject definition exists for the oid, false otherwise

getOidByName

public String getOidByName(String name)
                    throws LdapException

Gets the numericOid for a name/alias if one is associated. To prevent lookup failures due to case variance in the name, a failure to lookup the OID, will trigger a lookup using a lower cased version of the name and the name that failed to match will automatically be associated with the OID.

Specified by:

getOidByName in interface SchemaObjectRegistry<NameForm>

Parameters:

name - The name we are looking the oid for

Returns:

The numericOID associated with this name

Throws:

LdapException - If the OID can't be found

getSchemaName

public String getSchemaName(String oid)
                     throws LdapException

Gets the name of the schema this schema object is associated with.

Specified by:

getSchemaName in interface SchemaObjectRegistry<NameForm>

Parameters:

oid - the object identifier or the name

Returns:

the schema name

Throws:

LdapException - if the schema object does not exist

getType

public SchemaObjectType getType()

Specified by:

getType in interface SchemaObjectRegistry<NameForm>

Returns:

the type

iterator

public Iterator<NameForm> iterator()

Gets an iterator over the registered schema objects in the registry.

Specified by:

iterator in interface Iterable<NameForm>

Specified by:

iterator in interface SchemaObjectRegistry<NameForm>

Returns:

an Iterator of homogeneous schema objects

lookup

public NameForm lookup(String oid)
                throws LdapException

Looks up a SchemaObject by its unique Object Identifier or by name.

Specified by:

lookup in interface SchemaObjectRegistry<NameForm>

Parameters:

oid - the object identifier or name

Returns:

the SchemaObject instance for the id

Throws:

LdapException - if the SchemaObject does not exist

oidsIterator

public Iterator<String> oidsIterator()

Gets an iterator over the registered schema objects'OID in the registry.

Specified by:

oidsIterator in interface SchemaObjectRegistry<NameForm>

Returns:

an Iterator of OIDs

register

public void register(NameForm schemaObject)
              throws LdapException

Registers a new SchemaObject with this registry.

Specified by:

register in interface SchemaObjectRegistry<NameForm>

Parameters:

schemaObject - the SchemaObject to register

Throws:

LdapException - if the SchemaObject is already registered or the registration operation is not supported

renameSchema

public void renameSchema(String originalSchemaName,
                         String newSchemaName)
                  throws LdapException

Modify all the SchemaObject using a schemaName when this name changes.

Specified by:

renameSchema in interface SchemaObjectRegistry<NameForm>

Parameters:

originalSchemaName - The original Schema name

newSchemaName - The new Schema name

Throws:

LdapException - if the schema object does not exist

unregister

public NameForm unregister(String numericOid)
                    throws LdapException

Removes the SchemaObject registered with this registry, using its numeric OID.

Specified by:

unregister in interface SchemaObjectRegistry<NameForm>

Parameters:

numericOid - the numeric identifier

Throws:

LdapException - if the numeric identifier is invalid

unregisterSchemaElements

public void unregisterSchemaElements(String schemaName)
                              throws LdapException

Unregisters all SchemaObjects defined for a specific schema from this registry.

Specified by:

unregisterSchemaElements in interface SchemaObjectRegistry<NameForm>

Parameters:

schemaName - the name of the schema whose SchemaObjects will be removed from
