validate

void validate(DpTrans trans,
 ConfObject[] kp,
 ConfValue newval)
       throws DpCallbackException,
DpCallbackWarningException

The validate() callback should validate the values and throw a DpCallbackException if the validation fails. There is also a possibility to throw a DpCallbackWarningException with message set to a string describing the warning. The warnings will get propagated to the transaction engine, and depending on where the transaction originates, ConfD/NCS may or may not act on the warnings. If the transaction originates from the CLI or the Web UI, ConfD/NCS will interactively present the user with a choice - whereby the transaction can be aborted.

If the transaction originates from NETCONF - which does not have any interactive capabilities, the warnings are ignored. The warnings are primarily intended to alert inexperienced users that attempt to make - dangerous - configuration changes. There can be multiple warnings from multiple validation points in the same transaction.

Parameters:

trans - The transaction

kp - The keypath

newval - The new value to validate

Throws:

DpCallbackException - If the validation fails

DpCallbackWarningException - If a warning should be propagated to the originator of the transaction.
