ColumnDataType

Kind: Class

Source: Pams/Web/Pams.Web/Client/app/models/dashboard/data-source-schema/column-data-type.model.ts (line 2)

Part of: Pams

ColumnDataType represents the data type metadata for a column in the dashboard data-source schema. Its clone() method creates a separate copy of an existing instance so schema-related changes can be made without directly modifying the original object.

Methods

Properties

Where it refuses work

• ColumnDataType stops the work with an early return when model == null.

Usage

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

// Obtain a column data type from an existing schema definition.
const columnDataType: ColumnDataType = getColumnDataTypeFromSchema();

// Create a copy before applying schema-specific changes.
const copiedColumnDataType = columnDataType.clone();

// Keep the original instance unchanged when working with the copy.
updateColumnTypeForDashboard(copiedColumnDataType);

AI Coding Instructions

• Use clone() when a caller needs to change column type metadata without mutating the source schema instance.
• Keep ColumnDataType focused on column data-type representation and copying behavior.
• Preserve all existing property values when updating the clone() implementation.
• Check code that consumes data-source schema models when adding fields, so cloned instances include the new metadata.
