Overview

Abstract super class for default value generators. Stores the Context on initialization, and provides private helper methods to concrete subclasses.

Context key access: :call-seq:

dictionary => Hash-like with current key lookup dictionary.

Context value update: :call-seq:

update(key: value, ...)

Stop the processing of current rule chain: :call-seq:

stop

Wrap non-enumerable objects in an Array :call-seq:

enumerable(value) => value || [value]

Concrete subclasses must implement: :call-seq:

process(arg, &->(value))

arg

value

If a value was found it should be yield:ed
