/**
* This class provides a request control which may be included in a delete
* request to indicate that the server should completely remove the target
* entry, even if it would otherwise process the operation as a soft delete and
* merely hide the entry from most clients.
*
*
* NOTE: This class is part of the Commercial Edition of the UnboundID
* LDAP SDK for Java. It is not available for use in applications that
* include only the Standard Edition of the LDAP SDK, and is not supported for
* use in conjunction with non-UnboundID products.
*
*
* The criticality for this control may be either {@code TRUE} or {@code FALSE},
* but this will only impact how the delete request is to be handled by servers
* which do not support this control. A criticality of {@code TRUE} will cause
* any server which does not support this control to reject the request, while
* a criticality of {@code FALSE} should cause the delete request to be
* processed as if the control had not been included (i.e., as a regular "hard"
* delete).
*
* The control may optionally have a value. If a value is provided, then it
* must be the encoded representation of an empty ASN.1 sequence, like:
*
* HardDeleteRequestValue ::= SEQUENCE {
* ... }
*
* In the future, the value sequence may allow one or more elements to customize
* the behavior of the hard delete operation, but at present no such elements
* are defined.
* See the documentation for the {@link SoftDeleteRequestControl} class for an
* example demonstrating the use of this control.
*
* @see SoftDeleteRequestControl
