Constructor Detail

VirtualListViewClient

public VirtualListViewClient(ConnectionFactory cf,
                             SortKey... keys)

Creates a new virtual list view client.

Parameters:

cf - to get a connection from

keys - to supply to a sort request control

Method Detail

execute

public SearchResponse execute(SearchRequest request,
                              VirtualListViewParams params)
                       throws LdapException

Performs a search operation with the VirtualListViewRequestControl. The supplied request is modified in the following way:

• AbstractRequestMessage.setControls( RequestControl...) is invoked with SortRequestControl and VirtualListViewRequestControl and any other controls previously set on the search request.

Parameters:

request - search request to execute

params - virtual list view data

Returns:

search operation response

Throws:

LdapException - if the search fails

execute

public SearchResponse execute(SearchRequest request,
                              VirtualListViewParams params,
                              SearchResponse result)
                       throws LdapException

Performs a search operation with the VirtualListViewRequestControl. The supplied request is modified in the following way:

• AbstractRequestMessage.setControls( RequestControl...) is invoked with SortRequestControl and VirtualListViewRequestControl and any other controls previously set on the search request.

The content count and context id are extracted from the supplied response and replayed as appropriate in the request.

Parameters:

request - search request to execute

params - virtual list view data

result - of a previous VLV operation

Returns:

search operation response

Throws:

LdapException - if the search fails

executeToCompletion

public SearchResponse executeToCompletion(SearchRequest request,
                                          VirtualListViewParams params)
                                   throws LdapException

Performs a search operation with the VirtualListViewRequestControl. The supplied request is modified in the following way:

• AbstractRequestMessage.setControls( RequestControl...) is invoked with SortRequestControl and VirtualListViewRequestControl and any other controls previously set on the search request.

This method will continue to execute search operations until all search entries have been retrieved from the server. The returned response contains the response data of the last search result operation plus the entries and references returned by all previous search operations. The criteria used ot determine whether to continue searching is that the last response contained a cookie, produced a success result code, has a greater than zero contentCount and we have currently processed less entries than the contentCount.

The cookie used for each request is read from the cookie manager and written to the cookie manager after a successful search, if the response contains a cookie.

This method builds a synthetic response which contains the results of all search operations. Any ordering imposed by result handlers may be lost by this process.

Parameters:

request - search request to execute

params - virtual list view data

Returns:

search operation response of the last paged result operation

Throws:

LdapException - if the search fails

getResponseControl

public VirtualListViewResponseControl getResponseControl(SearchResponse result)

Returns the VirtualListViewResponseControl in the supplied response.

Parameters:

result - to inspect for a response control

Returns:

VLV response control or null if it does not exist

getVirtualListViewCookie

protected byte[] getVirtualListViewCookie(SearchResponse result)

Returns the VLV results cookie in the supplied response or null if no cookie exists.

Parameters:

result - of a previous VLV results operation

Returns:

VLV results cookie or null

appendRequestControls

private RequestControl[] appendRequestControls(SearchRequest request,
                                               VirtualListViewRequestControl cntrl)

Creates a new array of request controls which includes the VLV and sort controls. Any other request controls are in included
