Class MergeOperation

java.lang.Object

org.ldaptive.ext.MergeOperation

public class MergeOperation
extends Object

The merge operation performs the LDAP operations necessary to synchronize the data in an LdapEntry with its corresponding entry in the LDAP. The following logic is executed:

• if the entry does not exist in the LDAP, execute an add
• if the request is for a delete, execute a delete
• if the entry exists in the LDAP, execute a modify

LdapEntry.computeModifications(LdapEntry, LdapEntry) is used to determine the list of attribute modifications that are necessary to perform the merge. Either MergeRequest.getIncludeAttributes() or MergeRequest.getExcludeAttributes() will be used, but not both.

execute

public Result execute(MergeRequest request)
               throws LdapException

Executes a merge request. See OperationHandle.execute().

Parameters:

request - merge request

Returns:

merge result

Throws:

LdapException - if the connection cannot be opened

modify

protected Result modify(MergeRequest request,
                        LdapEntry source,
                        LdapEntry target)
                 throws LdapException

Retrieves the attribute modifications from LdapEntry.computeModifications(LdapEntry, LdapEntry) and executes a ModifyOperation with those results. If no modifications are necessary, no operation is performed.

Parameters:

request - merge request

source - ldap entry to merge into the LDAP

target - ldap entry that exists in the LDAP

Returns:

response of the modify operation or a null response if no operation is performed. If batching is enabled in the request, returns the response of the last operation performed

Throws:

LdapException - if an error occurs executing the modify operation

add

protected Result add(MergeRequest request,
                     LdapEntry entry)
              throws LdapException

Executes an AddOperation for the supplied entry.

Parameters:

request - merge request

entry - to add to the LDAP

Returns:

response of the add operation

Throws:

LdapException - if an error occurs executing the add operation

delete

protected Result delete(MergeRequest request,
                        LdapEntry entry)
                 throws LdapException

Executes a DeleteOperation for the supplied entry.

Parameters:

request - merge request

entry - to delete from the LDAP

Returns:

response of the delete operation

Throws:

LdapException - if an error occurs executing the deleting operation
