Constructor Details

This class inherits a constructor from DataMetaDom::Mapping

Class Method Details

.consumed?(model, src) ⇒ Boolean

Attempts to consume the instance from the given source, returns it if successful, returns nil otherwise.

  • Parameters

    • model - an instance of a Model

    • src - an instance of SourceFile

Returns:

  • (Boolean)
