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 a request control which may be used to request that
* entries below one or more base DNs be excluded from the results returned to
* a client while processing a search operation. For example, this may be
* useful in cases where you want to perform a search below "dc=example,dc=com",
* but want to exclude all entries below "ou=private,dc=example,dc=com".
*
*
* 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 criticality for this control may be either {@code true} or {@code false}.
* It must have a value with the following encoding:
*
* ExcludeBranchRequest ::= SEQUENCE {
