Method Detail

transform

@Nullable
Object transform(TypeInformation<?> type,

                           Object value)

Transforms the provided value to the requested type, if possible.

The contract is that a transformer must return an object of type T for a given type of TypeInformation<T>. This is not forced in the signature to allow handling primitive types, as well as to avoid casting nightmares.

Parameters:

type - the type to map to

value - the value to transform from

Returns:

the value of the given type, or null if not possible
