Constructor Detail

ImmutableDITContentRuleRegistry

public ImmutableDITContentRuleRegistry(DITContentRuleRegistry ditContentRuleRegistry)
Creates a new instance of ImmutableDITContentRuleRegistry.

Parameters:
ditContentRuleRegistry - The wrapped DITContentRule registry
Method Detail

copy

public ImmutableDITContentRuleRegistry copy()
Copy the DITContentRuleRegistry

Specified by:
copy in interface DITContentRuleRegistry
Specified by:
copy in interface SchemaObjectRegistry<DITContentRule>
Returns:
SchemaObjectRegistry The copied registry

size

public int size()

Specified by:
size in interface SchemaObjectRegistry<DITContentRule>
Returns:
The number of AttributeType stored

contains

public boolean contains(java.lang.String oid)
Checks to see if an SchemaObject exists in the registry, by its OID or name.

Specified by:
contains in interface SchemaObjectRegistry<DITContentRule>
Parameters:
oid - the object identifier or name of the SchemaObject
Returns:
true if a SchemaObject definition exists for the oid, false otherwise

getOidByName

public java.lang.String getOidByName(java.lang.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<DITContentRule>
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 java.lang.String getSchemaName(java.lang.String oid)
                               throws LdapException
Gets the name of the schema this schema object is associated with.

Specified by:
getSchemaName in interface SchemaObjectRegistry<DITContentRule>
Returns:
the schema name
Throws:
LdapException - if the schema object does not exist

getType

public SchemaObjectType getType()

Specified by:
getType in interface SchemaObjectRegistry<DITContentRule>
Returns:
the type

iterator

public java.util.Iterator<DITContentRule> iterator()
Gets an iterator over the registered schema objects in the registry.

Specified by:
iterator in interface java.lang.Iterable<DITContentRule>
Specified by:
iterator in interface SchemaObjectRegistry<DITContentRule>
Returns:
an Iterator of homogeneous schema objects

lookup

public DITContentRule lookup(java.lang.String oid)
                      throws LdapException
Looks up a SchemaObject by its unique Object Identifier or by name.

Specified by:
lookup in interface SchemaObjectRegistry<DITContentRule>
Parameters:
oid - the object identifier or name
Returns:
the SchemaObject instance for the id
Throws:
LdapException - if the SchemaObject does not exist

oidsIterator

public java.util.Iterator<java.lang.String> oidsIterator()
Gets an iterator over the registered schema objects'OID in the registry.

Specified by:
oidsIterator in interface SchemaObjectRegistry<DITContentRule>
Returns:
an Iterator of OIDs

register

public void register(DITContentRule schemaObject)
              throws LdapException
Registers a new SchemaObject with this registry.

Specified by:
register in interface SchemaObjectRegistry<DITContentRule>
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(java.lang.String originalSchemaName,
                         java.lang.String newSchemaName)
                  throws LdapException
Modify all the SchemaObject using a schemaName when this name changes.

Specified by:
renameSchema in interface SchemaObjectRegistry<DITContentRule>
Parameters:
originalSchemaName - The original Schema name
newSchemaName - The new Schema name
Throws:
LdapException - if the schema object does not exist

unregister

public DITContentRule unregister(java.lang.String numericOid)
                          throws LdapException
Removes the SchemaObject registered with this registry, using its numeric OID.

Specified by:
unregister in interface SchemaObjectRegistry<DITContentRule>
Parameters:
numericOid - the numeric identifier
Throws:
LdapException - if the numeric identifier is invalid

unregisterSchemaElements

public void unregisterSchemaElements(java.lang.String schemaName)
                              throws LdapException
