Class: CellEditorPool ​

Defined in: src/typescript/lib/component/table/cell/editor/CellEditorPool.ts:41

Per-table registry that holds at most one shared editor instance per editor variant.

Every cell in Body used to allocate its own editor up front, but only one cell can be edited at a time. The pool keeps the renderer-per-row model untouched while collapsing the N editors down to one instance per cell-provided key returned from Cell.getEditorKey. On CellEditorPool.acquire the editor is lazily constructed (and its blur/keydown listeners wired once), then re-used across every subsequent edit of the same variant.

Built-in keys are seeded by the constructor:

  • "string", "number", "date"
  • "time" / "time:seconds"
  • "datetime" / "datetime:seconds"

Custom cells can opt in by overriding Cell.getEditorKey and registering a factory via CellEditorPool.register before the first edit. Cells that return null from getEditorKey (e.g. BooleanCell, GlyphCell, DefaultCell) keep their legacy behaviour.

Constructors ​

new CellEditorPool() ​

ts
new CellEditorPool(): CellEditorPool

Defined in: src/typescript/lib/component/table/cell/editor/CellEditorPool.ts:50

Constructs a pool pre-seeded with factories for every built-in typed cell.

Returns ​

CellEditorPool

Methods ​

acquire() ​

ts
acquire(key: string, cell: Cell<any>): null | CellEditor<unknown>

Defined in: src/typescript/lib/component/table/cell/editor/CellEditorPool.ts:85

Returns the shared editor for key, lazily constructing it on first call and marking cell as the active edit target.

Parameters ​

key ​

string

The editor variant key returned by Cell.getEditorKey.

cell ​

Cell<any>

The cell that is starting an edit; receives subsequent blur/keydown events.

Returns ​

null | CellEditor<unknown>

The shared editor instance, or null if no factory is registered for key.

register() ​

ts
register(key: string, factory: CellEditorFactory): this

Defined in: src/typescript/lib/component/table/cell/editor/CellEditorPool.ts:70

Registers or overrides a factory for the given pool key.

Parameters ​

key ​

string

The editor variant key, matching Cell.getEditorKey.

factory ​

CellEditorFactory

A factory that constructs a fresh editor instance.

Returns ​

this

This pool, for method chaining.

Remarks ​

If an editor was already cached for the key it is dropped so the new factory runs on the next call to CellEditorPool.acquire.

release() ​

ts
release(): void

Defined in: src/typescript/lib/component/table/cell/editor/CellEditorPool.ts:106

Clears the active-cell pointer. Called by Cell when an edit commits or cancels.

Returns ​

void
