Part of: Pams

Column represents a column in a dashboard data-source schema. It supports copying an individual column with clone() and copying a collection of columns with cloneList() so callers can work with separate model instances.

Methods

Properties

Where it refuses work

• Column stops the work with an early return when model == null || model.length == 0.
• Column stops the work with an early return when model == null.

Usage

ts
import { Column } from './models/dashboard/data-source-schema/column.model';

const copiedColumn = column.clone();

const copiedColumns = Column.cloneList(schema.columns);

// Update copiedColumn or copiedColumns without changing the source instances.

AI Coding Instructions

• Call clone() before changing a Column that may also be referenced by another schema or view.
• Use Column.cloneList() when copying schema column collections instead of copying only the array reference.
• Keep column-copy behavior inside this model so consumers do not manually recreate column instances.
• Check whether calling code expects copied columns before adding mutations to dashboard schema flows.
