@NotMutable @ThreadSafety(level=COMPLETELY_THREADSAFE) public final class MatchingEntryCountResponseControl extends Control implements DecodeableControl
This class provides a response control that may be used to provide information about the number of entries that match a given set of search criteria. The control will be included in the search result done message for any successful search operation in which the request contained a matching entry count request control.
NOTE: This class, and other classes within the
com.unboundid.ldap.sdk.unboundidds
package structure, are only supported for use against Ping Identity, UnboundID, and Nokia/Alcatel-Lucent 8661 server products. These classes provide support for proprietary functionality or for external specifications that are not considered stable or mature enough to be guaranteed to work in an interoperable way with other types of LDAP servers.
The matching entry count response control has an OID of "1.3.6.1.4.1.30221.2.5.37", a criticality of false, and a value with the following encoding:MatchingEntryCountResponse ::= SEQUENCE { entryCount CHOICE { examinedCount [0] INTEGER, unexaminedCount [1] INTEGER, upperBound [2] INTEGER, unknown [3] NULL, ... } debugInfo [0] SEQUENCE OF OCTET STRING OPTIONAL, searchIndexed [1] BOOLEAN DEFAULT TRUE, ... }

createExactCountResponse
public static MatchingEntryCountResponseControl createExactCountResponse(int count, boolean examined, java.util.Collection<java.lang.String> debugInfo)
Creates a new matching entry count response control for the case in which the exact number of matching entries is known.- Parameters:
count
- The exact number of entries matching the associated search criteria. It must be greater than or equal to zero.examined
- Indicates whether the server examined the entries to exclude those entries that would not be returned to the client in a normal search with the same criteria.debugInfo
- An optional list of messages providing debug information about the processing performed by the server. It may benull
or empty if no debug messages should be included.- Returns:
- The matching entry count response control that was created.
-
createExactCountResponse
public static MatchingEntryCountResponseControl createExactCountResponse(int count, boolean examined, boolean searchIndexed, java.util.Collection<java.lang.String> debugInfo)
Creates a new matching entry count response control for the case in which the exact number of matching entries is known.- Parameters:
count
- The exact number of entries matching the associated search criteria. It must be greater than or equal to zero.examined
- Indicates whether the server examined the entries to exclude those entries that would not be returned to the client in a normal search with the same criteria.searchIndexed
- Indicates whether the search criteria is considered at least partially indexed and could be processed more efficiently than examining all entries with a full database scan.debugInfo
- An optional list of messages providing debug information about the processing performed by the server. It may benull
or empty if no debug messages should be included.- Returns:
- The matching entry count response control that was created.
-
