Constructor Detail

SingleFileLdifPartition

public SingleFileLdifPartition(org.apache.directory.api.ldap.model.schema.SchemaManager schemaManager,
                               DnFactory dnFactory)

Creates a new instance of SingleFileLdifPartition.

Parameters:

schemaManager - The SchemaManager instance

dnFactory - The DN factory

Method Detail

doInit

protected void doInit()
               throws org.apache.directory.api.ldap.model.exception.LdapException

Description copied from class: AvlPartition

Override this method to put your initialization code.

Overrides:

doInit in class AvlPartition

Throws:

org.apache.directory.api.ldap.model.exception.LdapException - If the initialization failed

add

public void add(AddOperationContext addContext)
         throws org.apache.directory.api.ldap.model.exception.LdapException

Adds an entry to this ContextPartition.

Specified by:

add in interface Partition

Overrides:

add in class AbstractBTreePartition

Parameters:

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

Throws:

org.apache.directory.api.ldap.model.exception.LdapException - if there are any problems

modify

public void modify(ModifyOperationContext modifyContext)
            throws org.apache.directory.api.ldap.model.exception.LdapException

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

Specified by:

modify in interface Partition

Overrides:

modify in class AbstractBTreePartition

Parameters:

modifyContext - 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:

org.apache.directory.api.ldap.model.exception.LdapException - if there are any problems

rename

public void rename(RenameOperationContext renameContext)
            throws org.apache.directory.api.ldap.model.exception.LdapException

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.

Specified by:

rename in interface Partition

Overrides:

rename in class AbstractBTreePartition

Parameters:

renameContext - the modify Dn context

Throws:

org.apache.directory.api.ldap.model.exception.LdapException - if there are any problems

move

public void move(MoveOperationContext moveContext)
          throws org.apache.directory.api.ldap.model.exception.LdapException

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

Specified by:

move in interface Partition

Overrides:

move in class AbstractBTreePartition

Parameters:

moveContext - The context containing the DNs to move

Throws:

org.apache.directory.api.ldap.model.exception.LdapException - if there are any problems

moveAndRename

public void moveAndRename(MoveAndRenameOperationContext opContext)
                   throws org.apache.directory.api.ldap.model.exception.LdapException

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.

Specified by:

moveAndRename in interface Partition

Overrides:

moveAndRename in class AbstractBTreePartition

Parameters:

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

Throws:

org.apache.directory.api.ldap.model.exception.LdapException - if there are any problems

delete

public org.apache.directory.api.ldap.model.entry.Entry delete(PartitionTxn partitionTxn,
                                                              String id)
                                                       throws org.apache.directory.api.ldap.model.exception.LdapException

Description copied from class: AbstractBTreePartition

Delete the entry associated with a given Id

Specified by:

delete in interface Store

Overrides:

delete in class AbstractBTreePartition

Parameters:

partitionTxn - The transaction to use

id - The id of the entry to delete

Returns:

the deleted entry if found

Throws:

org.apache.directory.api.ldap.model.exception.LdapException - If the deletion failed

doDestroy

protected void doDestroy(PartitionTxn partitionTxn)
                  throws org.apache.directory.api.ldap.model.exception.LdapException

Override this method to put your initialization code.

Overrides:

doDestroy in class AbstractBTreePartition

Parameters:

partitionTxn - The transaction to use

Throws:

org.apache.directory.api.ldap.model.exception.LdapException - If the destroy call failed

setEnableRewriting

public void setEnableRewriting(PartitionTxn partitionTxn,
                               boolean enableRewriting)
                        throws org.apache.directory.api.ldap.model.exception.LdapException

enable/disable the re-writing of partition data. This method internally calls the rewritePartitionData() method to save any dirty data if present

Parameters:

partitionTxn - The transaction to use

enableRewriting - flag to enable/disable re-writing

Throws:

org.apache.directory.api.ldap.model.exception.LdapException - If we weren't able to save the dirty data
