Field Detail

immutableComparatorRegistry

ComparatorRegistry immutableComparatorRegistry

The wrapped LdapComparator registry

Constructor Detail

ImmutableComparatorRegistry

public ImmutableComparatorRegistry(ComparatorRegistry comparatorRegistry)

Creates a new immutable ComparatorRegistry instance.

Parameters:

comparatorRegistry - The wrapped LdapComparator registry

Method Detail

register

public void register(LdapComparator<?> comparator)
              throws LdapException

Registers a new LdapComparator with this registry.

Specified by:

register in interface ComparatorRegistry

Specified by:

register in interface SchemaObjectRegistry<LdapComparator<?>>

Parameters:

comparator - the LdapComparator to register

Throws:

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

unregister

public LdapComparator<?> unregister(java.lang.String numericOid)
                             throws LdapException

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

Specified by:

unregister in interface ComparatorRegistry

Specified by:

unregister in interface SchemaObjectRegistry<LdapComparator<?>>

Parameters:

numericOid - the numeric identifier

Throws:

LdapException - if the numeric identifier is invalid

unregisterSchemaElements

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

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

Specified by:

unregisterSchemaElements in interface ComparatorRegistry

Specified by:

unregisterSchemaElements in interface SchemaObjectRegistry<LdapComparator<?>>

Parameters:

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

Throws:

LdapException

copy

public ImmutableComparatorRegistry copy()

Copy the ComparatorRegistry

Specified by:

copy in interface ComparatorRegistry

Specified by:

copy in interface SchemaObjectRegistry<LdapComparator<?>>

Returns:

SchemaObjectRegistry The copied registry

size

public int size()

Specified by:

size in interface SchemaObjectRegistry<LdapComparator<?>>

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<LdapComparator<?>>

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<LdapComparator<?>>

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<LdapComparator<?>>

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<LdapComparator<?>>

Returns:

the type

iterator

public java.util.Iterator<LdapComparator<?>> iterator()

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

Specified by:

iterator in interface java.lang.Iterable<LdapComparator<?>>

Specified by:

iterator in interface SchemaObjectRegistry<LdapComparator<?>>

Returns:

an Iterator of homogeneous schema objects

lookup

public LdapComparator<?> 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<LdapComparator<?>>

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<LdapComparator<?>>

Returns:

an Iterator of OIDs

renameSchema

                         java.lang.String newSchemaName)
                  throws LdapException

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

Specified by:

renameSchema in interface SchemaObjectRegistry<LdapComparator<?>>
