public final class MatchedValuesRequestControl extends Object implements Control
The matched values request control supports a subset of the LDAP filter type defined in RFC 4511, and is defined as follows:
ValuesReturnFilter ::= SEQUENCE OF SimpleFilterItem
SimpleFilterItem ::= CHOICE {
equalityMatch [3] AttributeValueAssertion,
substrings [4] SubstringFilter,
greaterOrEqual [5] AttributeValueAssertion,
lessOrEqual [6] AttributeValueAssertion,
present [7] AttributeDescription,
approxMatch [8] AttributeValueAssertion,
extensibleMatch [9] SimpleMatchingAssertion }
SimpleMatchingAssertion ::= SEQUENCE {
matchingRule [1] MatchingRuleId OPTIONAL,
type [2] AttributeDescription OPTIONAL,
--- at least one of the above must be present
matchValue [3] AssertionValue}
For example Barbara Jensen's entry contains two common name values, Barbara
Jensen and Babs Jensen. The following code retrieves only the latter.
String DN = "uid=bjensen,ou=People,dc=example,dc=com";
SearchRequest request = Requests.newSearchRequest(DN,
SearchScope.BASE_OBJECT, "(objectclass=*)", "cn")
.addControl(MatchedValuesRequestControl
.newControl(true, "(cn=Babs Jensen)"));
// Get the entry, retrieving cn: Babs Jensen, not cn: Barbara Jensen
SearchResultEntry entry = connection.searchSingleEntry(request);

public boolean hasValue()
true if this control has a value. In some circumstances
it may be useful to determine if a control has a value, without actually
calculating the value and incurring any performance costs.public boolean isCritical()
true if it is unacceptable to perform the operation
without applying the semantics of this control.
The criticality field only has meaning in controls attached to request
messages (except UnbindRequest). For controls attached to response
messages and the UnbindRequest, the criticality field SHOULD be
false, and MUST be ignored by the receiving protocol peer. A
value of true indicates that it is unacceptable to perform the
operation without applying the semantics of the control.
isCritical in interface Controltrue if this control must be processed by the Directory
Server, or false if it can be ignored.Copyright © 2011-2015 ForgeRock AS. All Rights Reserved.
