initialize

void initialize()
                throws Exception

Initializes this partition.

Throws:

Exception - if initialization fails in any way

IllegalStateException - if the Partition has not been initialized

destroy

void destroy()
             throws Exception

Instructs this Partition to synchronize with it's persistent store, and destroy all held resources, in preparation for a shutdown event.

Throws:

Exception

isInitialized

boolean isInitialized()

Checks to see if this partition is initialized or not.

Returns:

true if the partition is initialized, false otherwise

sync

void sync()
          throws Exception

Flushes any changes made to this partition now.

Throws:

Exception - if buffers cannot be flushed to disk

delete

void delete(DeleteOperationContext opContext)
            throws Exception

Deletes a leaf entry from this ContextPartition: non-leaf entries cannot be deleted until this operation has been applied to their children.

Parameters:

opContext - the context of the entry to delete from this ContextPartition.

Throws:

Exception - if there are any problems

add

void add(AddOperationContext opContext)
         throws Exception

Adds an entry to this ContextPartition.

Parameters:

opContext - the context used to add and entry to this ContextPartition

Throws:

Exception - if there are any problems

modify

void modify(ModifyOperationContext opContext)
            throws Exception

Modifies an entry by adding, removing or replacing a set of attributes.

Parameters:

opContext - The context containing the modification operation to perform on the entry which is one of constants specified by the DirContext interface: ADD_ATTRIBUTE, REMOVE_ATTRIBUTE, REPLACE_ATTRIBUTE.

Throws:

Exception - if there are any problems

See Also:

DirContext, DirContext.ADD_ATTRIBUTE, DirContext.REMOVE_ATTRIBUTE, DirContext.REPLACE_ATTRIBUTE

list

EntryFilteringCursor list(ListOperationContext opContext)
                          throws Exception

A specialized form of one level search used to return a minimal set of information regarding child entries under a base. Convenience method used to optimize operations rather than conducting a full search with retrieval.

Parameters:

opContext - the context containing the distinguished/absolute name for the search/listing

Returns:

a NamingEnumeration containing objects of type ServerSearchResult

Throws:

Exception - if there are any problems

search

EntryFilteringCursor search(SearchOperationContext opContext)
                            throws Exception

Conducts a search against this ContextPartition. Namespace specific parameters for search are contained within the environment using namespace specific keys into the hash. For example in the LDAP namespace a ContextPartition implementation may look for search Controls using a namespace specific or implementation specific key for the set of LDAP Controls.

Parameters:

opContext - The context containing the information used by the operation

Returns:

a NamingEnumeration containing objects of type

Throws:

Exception - if there are any problems

lookup

ClonedServerEntry lookup(LookupOperationContext lookupContext)
                         throws Exception

Looks up an entry by distinguished/absolute name. This is a simplified version of the search operation used to point read an entry used for convenience. Depending on the context parameters, we my look for a simple entry, or for a restricted set of attributes for this entry

Parameters:

lookupContext - The context containing the parameters

Returns:

an Attributes object representing the entry

Throws:

Exception - if there are any problems

hasEntry

boolean hasEntry(EntryOperationContext opContext)
                 throws Exception

Fast operation to check and see if a particular entry exists.

Parameters:

opContext - The context used to pass informations

Returns:

true if the entry exists, false if it does not

Throws:

Exception - if there are any problems

rename

void rename(RenameOperationContext opContext)
            throws Exception

Modifies an entry by changing its relative name. Optionally attributes associated with the old relative name can be removed from the entry. This makes sense only in certain namespaces like LDAP and will be ignored if it is irrelevant.

Parameters:

opContext - the modify DN context

Throws:

Exception - if there are any problems

move

void move(MoveOperationContext opContext)
          throws Exception

Transplants a child entry, to a position in the namespace under a new parent entry.

Parameters:

opContext - The context containing the DNs to move

Throws:

Exception - if there are any problems

moveAndRename

void moveAndRename(MoveAndRenameOperationContext opContext)
                   throws Exception

Transplants a child entry, to a position in the namespace under a new parent entry and changes the RN of the child entry which can optionally have its old RN attributes removed. The removal of old RN attributes may not make sense in all namespaces. If the concept is undefined in a namespace this parameters is ignored. An example of a namespace where this parameter is significant is the LDAP namespace.

Parameters:

opContext - The context contain all the information about the modifyDN operation

Throws:

Exception - if there are any problems

bind

void bind(BindOperationContext opContext)
          throws Exception

Represents a bind operation issued to authenticate a client. Partitions need not support this operation. This operation is here to enable those interested in implementing virtual directories with ApacheDS.

Parameters:

opContext - the bind context, containing all the needed informations to bind

Throws:

Exception - if something goes wrong

unbind

void unbind(UnbindOperationContext opContext)
            throws Exception

Represents an unbind operation issued by an authenticated client. Partitions need not support this operation. This operation is here to enable those interested in implementing virtual directories with ApacheDS.

Parameters:

opContext - the context used to unbind

Throws:

Exception - if something goes wrong
