value - the stringified id with the protocol and ObjectID.DELIMITER already removed, and which is never null or zero length

Returns:

the ObjectID instance for the stringified ID if this factory is able to parse the string, or null if the factory is unaware of the specified format.

Throws:

InvalidIDException - if the parser is aware of this protocol, but it is of the wrong format for this type of ObjectID.

validate

This implementation only checks whether the ObjectID is an instance of a LongID.

Overrides:

validate in class LongIDFactory

Parameters:

id - the ID that is to be validated, and which is never null

Returns:

true if the instance is valid for this protocol, or false if it is not valid.
