Interface EnumSetter<F extends Enum<F>,T>

Type Parameters:
F - An enum type which describes distinct fields which may be modified.
T - A target configurable type to be configured.
public interface EnumSetter<F extends Enum<F>,T>
Provide a way to configure a target object of type T, given an enumeration which describes the distinct property types which could be configured. This method provides an efficient method for refining a template or builder object with O(1) field lookup.

The field enum doesn't limit how a field may be modified. In some cases, a single field may be iteratively built-up, such as headers for a request object. (Multiple headers can be added, and they are all a header type, just with different values.) In other cases, there may be a single-valued property that is replaced entirely each time it is set.

    T

    • setField

      T setField(T target, F field, Object... value)
      Given a target configurable of type T and a field type identifier from enum type K, set or add a value to the field described by K, and then return the target configurable.
      Parameters:
      target - The object to be augmented.
      field - The enum which describes the type of field mutation.
      value - The object values to assign to the named field. If a given field type can be a collection, like a map, then these might be a 2-tuple of key-value. Semantics of the value objects are always specific to the type of field being configured.
      Returns:
      A modified object, possibly a new instance, as with functional property modifiers.
