Parameters:

value - to be encoded

Returns:

a string representation of the value, or the value's identity

toValue

public  clientValue)

Converts a client-side representation, provided by ValueEncoder.toClient(Object), back into a server-side value.

Specified by:

toValue in interface ValueEncoder<E>

Parameters:

clientValue - string representation of the value's identity

Returns:

the corresponding entity, or null if not found
