/**
* This class provides an implementation of an extended request which may be
* used to retrieve a batch of changes from a Directory Server.
*
*
* NOTE: This class, and other classes within the
* {@code 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 changelog batch request value is encoded as follows:
*
* The following example demonstrates the use of the get changelog batch to
* iterate across all entries in the changelog. It will operate in an infinite
* loop, starting at the beginning of the changelog and then reading 1000
* entries at a time until all entries have been read. Once the end of the
* changelog has been reached, it will continue looking for changes, waiting for
* up to 5 seconds for new changes to arrive.
*
* ChangelogBatchStartingPoint startingPoint =
* new BeginningOfChangelogStartingPoint();
* while (true)
* {
* GetChangelogBatchExtendedRequest request =
* new GetChangelogBatchExtendedRequest(startingPoint, 1000, 5000L);
*
* GetChangelogBatchExtendedResult result =
* (GetChangelogBatchExtendedResult)
* connection.processExtendedOperation(request);
* List<ChangelogEntryIntermediateResponse> changelogEntries =
* result.getChangelogEntries();
*
* startingPoint = new ResumeWithTokenStartingPoint(result.getResumeToken());

/**
* Encodes the value for this extended request using the provided information.
*
* @param startingPoint An object which indicates the
* starting point for the batch of
* changes to retrieve. It must not
* be {@code null}.
* @param maxChanges The maximum number of changes that
* should be retrieved before the
* server should return the
* corresponding extended result. A
* value less than or equal to zero
* may be used to indicate that the
* server should not return any
* entries but should just return a
* result containing a token which
* represents the starting point.
* @param maxWaitTimeMillis The maximum length of time in
* milliseconds to wait for changes.
* A value less than or equal to zero
* indicates that there should not be
* any wait and the result should be
* returned as soon as all
* immediately-available changes (up
* to the specified maximum count)
* have been returned.
* @param waitForMaxChanges Indicates whether the server should
* wait for up to the maximum length
* of time for up to the maximum
* number of changes to be returned.
* If this is {@code false}, then the
* result will be returned as soon as
* any changes are available (after
* sending those changes), even if the
* number of available changes is less
* than {@code maxChanges}.
* Otherwise, the result will not be
* returned until either the maximum
* number of changes have been
* returned or the maximum wait time
* has elapsed.
* @param includeBaseDNs A list of base DNs for entries to
* include in the set of changes to be
* returned.
* @param excludeBaseDNs A list of base DNs for entries to
* exclude from the set of changes to
* be returned.
* @param changeTypes The types of changes that should be
* returned. If this is {@code null}
* or empty, then all change types
* will be included.
* @param continueOnMissingChanges Indicates whether the server should
* make a best-effort attempt to
* return changes even if the starting
* point represents a point that is
* before the first available change
* in the changelog and therefore the
* results returned may be missing
* changes.
* @param pareEntriesForUserDN The DN of a user for whom to pare
* down the contents of changelog
* entries based on the access control
* and sensitive attribute
* restrictions defined for that user.
* It may be {@code null} if changelog
* entries should not be pared down
* for any user, an empty string if
* changelog entries should be pared
* down to what is available to
* anonymous users, or a user DN to
* pare down entries for the specified
* user.
* @param changeSelectionCriteria The optional criteria to use to
* pare down the changelog entries
* that should be returned. It may be
* {@code null} if all changelog
* entries should be returned.
* @param includeSoftDeletedEntryMods Indicates whether to include
* changelog entries that represent
* changes to soft-deleted entries.
* @param includeSoftDeletedEntryDeletes Indicates whether to include
* changelog entries that represent
* deletes of soft-deleted entries.
*
* @return The value for the extended request.
