Overview

An ObservationMatrixColumn defines the column in an observation matrix. ObservationMatrixColumn items are only created and destroyed through references to ObservationMatrixColumnItems, never directly!

Instance Attribute Details

#cached_observation_matrix_column_item_id ⇒ Integer

Returns if the reference_count is 1, and the presence of this column is here because of reference to a /Single/ ObservationMatrixColumnItem column, then cache the ID of that column.

Returns:

  • (Integer) —

    if the reference_count is 1, and the presence of this column is here because of reference to a /Single/ ObservationMatrixColumnItem column, then cache the ID of that column
