Included in:
Attribute
Defined in:

Overview

WHAT AN ATTRIBUTE DOES. The declared half — name, type, list, default, optional, pattern, admits — is what the language states in aggregate.bluebook's own Field. These are the questions readers ask ABOUT that shape, which no declaration states.

MAY THIS FACT BE LEFT OUT?

Required is the default and by far the common case — a command takes the arguments it declares, and all of them — so the EXCEPTION is what gets marked. Marking the other way would annotate almost every attribute in the corpus to say nothing.

Only a COMMAND enforces this. An aggregate's own attributes are filled by the commands that set them, and a value object's by its constructor ; neither is a payload anyone hands in.

Returns:

  • (Boolean)
