public class GetChunkedResultRequest

extends com.novell.nds.dirxml.ldap.DirXMLRequest

implements ExtendedRequest

Get part of a large result that is created in response to another data request.

To use this class with the Novell Java LDAP SDK create an instance and call LDAPConnection.extendedOperation with the instance as the LDAPExtendedOperation parameter.

If the corresponding response class has been registered then the return from LDAPConnection.extendedOperation will be an instance of the response class.

To use this class with Java LDAP JNDI create an instance and call LdapContext.extendedOperation with the instance as the ExtendedRequest parameter.

The return from LdapContext.extendedOperation will be an instance of the response class.

Rights needed:

The same rights that were needed for the request that generated the results.

OID:

2.16.840.1.113719.1.14.100.33

Request data:

 ASN1Integer     data handle
 ASN1Integer     maximum data amount to return (64K is approximate maximum)
 ASN1Integer     additional timeout value in minutes for result data (0-10 are legal values)
 

Notes:

The "data handle" is that returned by the request that generated the results.

GetChunkedResultRequest

public GetChunkedResultRequest(int dataHandle,
                               int maxReturnSize,
                               int additionalTimeout)
                        throws LDAPException

Construct an LDAP extended operation to get part or all of a large set of data that results from another request.

Parameters:

dataHandle - handle returned from DirXML LDAP extended operation that returns large results

maxReturnSize - maximum size of data chunk to return

additionalTimeout - additional timeout in minutes for server-hosted data (0-10, not range checked)

Method Detail

getEncodedValue

public byte[] getEncodedValue()

Return the LBER-encoded data for this request. This is an implementation method for the JNDI ExtendedRequest interface.

Specified by:

getEncodedValue in interface ExtendedRequest

Returns:

LBER-encoded data or null, if there is no request data.

createExtendedResponse

public ExtendedResponse createExtendedResponse(String id,
                                               byte[] berValue,
                                               int offset,
                                               int length)
                                        throws NamingException

Create the ExtendedResponse-implementing object that corresponds to this request. This is an implementation method for the JNDI ExtendedRequest interface.

Specified by:

createExtendedResponse in interface ExtendedRequest

Parameters:

id - (ignored)

berValue - contains LBER-encoded response data

offset - offset into berValue

length - length (in bytes) of reponse data

Throws:

NamingException
