@jsvision/datagrid / ErrorRegistry

Interface: ErrorRegistry ​

Defined in: datagrid/src/error-registry.ts:16

A reactive registry of cells whose last commit was blocked, each with a message, plus the active one.

Methods ​

active() ​

active(): string | null

Defined in: datagrid/src/error-registry.ts:26

The current active message to show in the band, or null — a reactive read.

Returns ​

string | null

clear() ​

clear(key): void

Defined in: datagrid/src/error-registry.ts:20

Clear a cell. If it held the active message, the band recomputes to the next still-invalid cell.

Parameters ​

key ​

string

Returns ​

void

has() ​

has(key): boolean

Defined in: datagrid/src/error-registry.ts:22

Whether a cell is invalid — a reactive read (re-runs in an effect on change).

Parameters ​

key ​

string

Returns ​

boolean

keys() ​

keys(): ReadonlySet<string>

Defined in: datagrid/src/error-registry.ts:35

The invalid-cell key set (for the paint pass) — a reactive read.

Returns ​

ReadonlySet<string>

message() ​

message(key): string | undefined

Defined in: datagrid/src/error-registry.ts:24

The message for a cell, or undefined — a reactive read.

Parameters ​

key ​

string

Returns ​

string | undefined

note() ​

note(message): void

Defined in: datagrid/src/error-registry.ts:33

Push (or clear, with null) a transient message that has no cell key — used by the row gate for a cross-field message not anchored to one invalid cell. It shares the single last-writer-wins active channel with keyed set. note(null) recomputes the active message to the most-recent still-invalid keyed cell (else null), so clearing a transient message never hides one a red cell still needs.

Parameters ​

message ​

string | null

Returns ​

void

set() ​

set(key, message): void

Defined in: datagrid/src/error-registry.ts:18

Mark a cell invalid with message; it also becomes the active (band) message.

Parameters ​

key ​

string

message ​

string

Returns ​

void
