Method Detail

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<T extends SchemaObject>

Parameters:

oid - the object identifier or name of the SchemaObject

Returns:

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

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<T extends SchemaObject>

Parameters:

oid - the object identifier or the name

Returns:

the schema name

Throws:

LdapException - if the schema object does not exist

renameSchema

public void renameSchema(String originalSchemaName,
                         String newSchemaName)

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

Specified by:

renameSchema in interface SchemaObjectRegistry<T extends SchemaObject>

Parameters:

originalSchemaName - The original Schema name

newSchemaName - The new Schema name

iterator

public Iterator<T> iterator()

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

Specified by:

iterator in interface Iterable<T extends SchemaObject>

Specified by:

iterator in interface SchemaObjectRegistry<T extends SchemaObject>

Returns:

an Iterator of homogeneous schema objects

oidsIterator

public Iterator<String> oidsIterator()

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

Specified by:

oidsIterator in interface SchemaObjectRegistry<T extends SchemaObject>

Returns:

an Iterator of OIDs

lookup

public T lookup(String oid)
                              throws LdapException

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

Specified by:

lookup in interface SchemaObjectRegistry<T extends SchemaObject>

Parameters:

oid - the object identifier or name

Returns:

the SchemaObject instance for the id

Throws:

LdapException - if the SchemaObject does not exist

register

public void register(T schemaObject)
              throws LdapException

Registers a new SchemaObject with this registry.

Specified by:

register in interface SchemaObjectRegistry<T extends SchemaObject>

Parameters:

schemaObject - the SchemaObject to register

Throws:

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

unregister

public T unregister(String numericOid)
                                  throws LdapException

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

Specified by:

unregister in interface SchemaObjectRegistry<T extends SchemaObject>

Parameters:

numericOid - the numeric identifier

Throws:

LdapException - if the numeric identifier is invalid

unregister

public T unregister(T schemaObject)
                                  throws LdapException

Removes the SchemaObject registered with this registry.

Specified by:

unregister in interface SchemaObjectRegistry<T extends SchemaObject>

Parameters:

schemaObject - the schemaObject to unregister

Throws:

LdapException - if the schemaObject can't be unregistered 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<T extends SchemaObject>

Parameters:

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

Throws:

LdapException

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<T extends SchemaObject>

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

copy

public SchemaObjectRegistry<T> copy(SchemaObjectRegistry<T> original)

get

public T get(String oid)

Gets the SchemaObject associated with a given OID.

Specified by:

get in interface SchemaObjectRegistry<T extends SchemaObject>

Parameters:

oid - The SchemaObject's OID we are looking for

Returns:

The SchemaObject, if any. Null otherwise

getType

public SchemaObjectType getType()

Specified by:

getType in interface SchemaObjectRegistry<T extends SchemaObject>

Returns:

the type

size

public int size()

Specified by:

size in interface SchemaObjectRegistry<T extends SchemaObject>

Returns:

The number of AttributeType stored

toString

public String toString()

Overrides:

toString in class Object

See Also:

Object.toString()

clear

public void clear()

Clear the registry from all its content
