Compare() public method

Asynchronously compares an attribute value with one in the directory, using the specified queue. Please note that a successful completion of this command results in one of two status codes: LdapException.COMPARE_TRUE if the entry has the value, and LdapException.COMPARE_FALSE if the entry does not have the value or the attribute.
LdapException A general exception which includes an error /// message and an Ldap error code. /// ///
public Compare ( System dn, LdapAttribute attr, LdapResponseQueue queue ) : LdapResponseQueue
dn System The distinguished name of the entry containing an /// attribute to compare. /// ///
attr LdapAttribute An attribute to compare. /// ///
queue LdapResponseQueue The queue for messages returned from a server in /// response to this request. If it is null, a /// queue object is created internally. /// ///
return LdapResponseQueue
