public LDAPSearchConstraints()
Constructs anLDAPSearchConstraints
object that specifies the default set of search constraints.
public LDAPSearchConstraints(int msLimit, int dereference, int maxResults, boolean doReferrals, int batchSize, LDAPRebind rebind_proc, int hop_limit)
Constructs a newLDAPSearchConstraints
object and allows you to specify the search constraints in that object.
- Parameters:
msLimit
- maximum time in milliseconds to wait for results (0 by default, which means that there is no maximum time limit)dereference
- eitherLDAPv2.DEREF_NEVER
,LDAPv2.DEREF_FINDING
,LDAPv2.DEREF_SEARCHING
, orLDAPv2.DEREF_ALWAYS
(see LDAPConnection.setOption).LDAPv2.DEREF_NEVER
is the default.maxResults
- maximum number of search results to return (1000 by default)doReferrals
- specifytrue
to follow referrals automatically, orfalse
to throw anLDAPReferralException
error if the server sends back a referral (false
by default)batchSize
- specify the number of results to return at a time (1 by default)rebind_proc
- specifies the object of the class that implements theLDAPRebind
interface (you need to define this class). The object will be used when the client follows referrals automatically. The object provides the client with a method for getting the distinguished name and password used to authenticate to another LDAP server during a referral. (This field isnull
by default.)hop_limit
- maximum number of referrals to follow in a sequence when attempting to resolve a request

public Object clone()
Makes a copy of an existing set of search constraints.
- Overrides:
- clone in interface LDAPConstraints
- Returns:
- a copy of an existing set of search constraints.
public int getBatchSize()
Returns the suggested number of results to return at a time during search. This should be 0 if intermediate results are not needed, and 1 if results are to be processed as they come in.
- Returns:
- number of results to return at a time.
public int getDereference()
Specifies how aliases should be dereferenced.
- Returns:
LDAPv2.DEREF_NEVER
to never follow ("dereference") aliases,LDAPv2.DEREF_FINDING
to dereference when finding the starting point for the search (but not when searching under that starting entry),LDAPv2.DEREF_SEARCHING
to dereference when searching the entries beneath the starting point of the search (but not when finding the starting entry), orLDAPv2.DEREF_ALWAYS
to always dereference aliases.
public int getMaxBacklog()
Deprecated. Use
LDAPConnection.getOption()
Get the maximum number of unread entries any search listener can have before we stop reading from the server.
- Returns:
- the maximum number of unread entries per listener.
public int getMaxResults()
Returns the maximum number of search results that are to be returned; 0 means there is no limit.
- Returns:
- maximum number of search results to be returned.
public int getReferralErrors()
Reports if errors when following search continuation references are to cause processing of the remaining results to be aborted. If an LDAP server does not contain an entry at the base DN for a search, it may be configured to return a referral. If it contains an entry at the base DN of a subtree search, one or more of the child entries may contain search continuation references. The search continuation references are returned to the client, which may follow them by issuing a search request to the host indicated in the search reference. If theLDAPConnection
object has been configured to follow referrals automatically, it may fail when issuing a search request to the host indicated in a search reference, e.g. because there is no entry there, because it does not have credentials, because it does not have sufficient permissions, etc. If the client aborts evaluation of the search results (obtained throughLDAPSearchResults
) when a search reference cannot be followed, any remaining results are discarded. Up to version 4.17 of the Java LDAP SDK, the SDK printed an error message but continued to process the remaining search results and search continuation references. As of SDK version 4.17, the default behavior is still to continue processing any remaining search results and search continuation references if there is an error following a referral, but the behavior may be changed withsetReferralErrors
to throw an exception instead.
- Returns:
REFERRAL_ERROR_CONTINUE
if remaining results are to be processed when there is an error following a search continuation reference,REFERRAL_ERROR_EXCEPTION
if such an error is to cause anLDAPException
.
- Since:
- LDAPJDK 4.17
public int getServerTimeLimit()
Returns the maximum number of seconds to wait for the server to spend on a search operation.If 0, there is no time limit.
- Returns:
- maximum number of seconds for the server to spend.
public void setBatchSize(int batchSize)
Sets the suggested number of results to return at a time during search. This should be 0 if intermediate results are not needed, and 1 if results are to be processed as they come in. (By default, this is 1.)
- Parameters:
batchSize
- number of results to return at a time
public void setDereference(int dereference)
Sets a preference indicating how aliases should be dereferenced.
- Parameters:
dereference
-LDAPv2.DEREF_NEVER
to never follow ("dereference") aliases,LDAPv2.DEREF_FINDING
to dereference when finding the starting point for the search (but not when searching under that starting entry),LDAPv2.DEREF_SEARCHING
to dereference when searching the entries beneath the starting point of the search (but not when finding the starting entry), orLDAPv2.DEREF_ALWAYS
to always dereference aliases
public void setMaxBacklog(int backlog)
Deprecated. Use
LDAPConnection.setOption()
Set the maximum number of unread entries any search listener can have before we stop reading from the server.
- Parameters:
backlog
- the maximum number of unread entries per listener
public void setMaxResults(int maxResults)
Sets the maximum number of search results to return; 0 means there is no limit. (By default, this is set to 1000.)
- Parameters:
maxResults
- maximum number of search results to return
public void setReferralErrors(int errorBehavior)
Specifies if errors when following search continuation references are to cause processing of the remaining results to be aborted. If an LDAP server does not contain an entry at the base DN for a search, it may be configured to return a referral. If it contains an entry at the base DN of a subtree search, one or more of the child entries may contain search continuation references. The search continuation references are returned to the client, which may follow them by issuing a search request to the host indicated in the search reference. If theLDAPConnection
object has been configured to follow referrals automatically, it may fail when issuing a search request to the host indicated in a search reference, e.g. because there is no entry there, because it does not have credentials, because it does not have sufficient permissions, etc. If the client aborts evaluation of the search results (obtained throughLDAPSearchResults

Up to version 4.17 of the Java LDAP SDK, the SDK printed an error message but continued to process the remaining search results and search continuation references. As of SDK version 4.17, the default behavior is still to continue processing any remaining search results and search continuation references if there is an error following a referral, but the behavior may be changed withsetReferralErrors

- Parameters:
errorBehavior
- EitherREFERRAL_ERROR_CONTINUE
if remaining results are to be processed when there is an error following a search continuation reference orREFERRAL_ERROR_EXCEPTION
if such an error is to cause anLDAPException

public void setServerTimeLimit(int limit)
Sets the maximum number of seconds for the server to spend returning search results. If 0, there is no time limit.
