/**
*
* This class provides an LDAP interface for object based
* restore of eDirectory objects.
*
* The information need for restore includes such items as object DN,
* data buffer length, string containing the number of chunks and each chunk
* elements representing the size of each chunk, data blob in byte[]. The API
* support restoring of both non-encrypted and encrypted objects.
*
*
* To send this request to eDirectory, you must
* create an instance of this class and then call the
* extendedOperation method with this object as the required
* LDAPExtendedOperation parameter.
*
* The getLDAPRestoreRequest extension uses the following OID:
* 2.16.840.1.113719.1.27.100.98
*
* The requestValue has the following format:
*
*
requestValue ::=
* objectDN ::= LDAPDN
* passwd ::= OCTET STRING
* bufferLength ::= INTEGER
* retunedBuffer::= OCTET STRING
* dataChunkSizes ::=
*
* SEQUENCE {
*
*
* noOfChunks INTEGER
*
* SET of [
*
*
*
* SEQUENCE of {eacChunksize INTEGER}]
*
*
* }
