The UnboundID LDAP SDK for Java is a fast, comprehensive, and easy-to-use
Java API for communicating with LDAP directory servers and performing
related tasks like reading and writing LDIF, encoding and decoding data
using base64 and ASN.1 BER, and performing secure communication. This
package contains the Standard Edition of the LDAP SDK, which is a
complete, general-purpose library for communicating with LDAPv3 directory
servers.

* This class provides an implementation of the stream proxy values extended

* Directory Proxy Server. It may be used to obtain all entry DNs and/or all
* values for one or more attributes for a specified portion of the DIT.
*
*
* 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.
*
*
* This extended request has an OID of "1.3.6.1.4.1.30221.2.6.8" and the value
* is encoded as follows:
*
* StreamProxyValuesRequest ::= SEQUENCE {
* baseDN [0] LDAPDN,
* includeDNs [1] DNSelection OPTIONAL,
* attributes [2] SEQUENCE OF LDAPString OPTIONAL,
* valuesPerResponse [3] INTEGER (1 .. 32767) OPTIONAL,
* backendSets [4] SEQUENCE OF BackendSetConfig,
* ... }
*
* DNSelection ::= SEQUENCE {

* baseObject (0),
* singleLevel (1),
* wholeSubtree (2),

* ... }
* relative [1] BOOLEAN DEFAULT TRUE,
