Method Details

transform

default <E> DataTransactionResult transform(Key<? extends Value<E>> key,
 Function<E,E> function)

Applies a transformation on the provided Value such that the return value of Function.apply(Object) will become the end resulting value set into this DataHolder.Mutable. It is not necessary that the input is actually present, in which case the Keyed data is compatible, but not necessarily present. Writing a Function to properly handle the potential for a null input is required for this method to execute without exception.

Type Parameters:

E - The type of value

Parameters:

key - The key linked to

function - The function to manipulate the value

Returns:

The end resulting value

transform

default <E> DataTransactionResult transform(Supplier<? extends Key<? extends Value<E>>> key,
 Function<E,E> function)

Applies a transformation on the provided Value such that the return value of Function.apply(Object) will become the end resulting value set into this DataHolder.Mutable. It is not necessary that the input is actually present, in which case the Keyed data is compatible, but not necessarily present. Writing a Function to properly handle the potential for a null input is required for this method to execute without exception.

Returns:

The end resulting value

value - The value to set

Returns:

The transaction result

Throws:

IllegalArgumentException - If the result is a failure likely due to incompatibility
