接口 ColumnSource

  • 所有超级接口:
    RelationalValueSource
    public interface ColumnSource
extends RelationalValueSource
    Contract for source information pertaining to a physical column definition specific to a particular attribute context.

    Conceptual note: this really describes a column from the perspective of its binding to an attribute, not necessarily the column itself.
