Overview
A convenient wrapper for data processed by schemas
Values are available within the rule blocks. They act as hash-like objects and expose a convenient API for accessing data.
Instance Attribute Summary collapse
-
#data ⇒ Hash
readonly
private
Schema’s result output.
Instance Method Summary collapse
-
#[](*args) ⇒ Object
Read from the provided key.
-
#initialize(data) ⇒ Values
constructor
private
A new instance of Values.
- #key?(key, hash = data) ⇒ Boolean

Constructor Details
#initialize(data) ⇒ Values
This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.
Returns a new instance of Values.

Dynamic Method Handling
This class handles dynamic methods through the method_missing method
#method_missing(meth, *args, &block) ⇒ Object (private)
This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.
