GenomeSpy Core API / PointSelectionApi

Interface: PointSelectionApi¶

Capability for reading and clearing a row-backed point selection.

Point selections are exposed as detached snapshots. Use clear() to empty the selection; writes through this capability are not supported.

"commit" is accepted for future gesture-based point selections, such as a lasso. For the current point-selection implementation, it has the same delivery behavior as "change".

Properties¶

type¶

readonly type: "point"

Discriminator for this selection capability.

getValue¶

getValue: () => PointSnapshot

Returns the current detached selection snapshot.

Returns¶

PointSnapshot

subscribe¶

subscribe: (listener, options?) => () => void

Subscribes to future selection updates and returns an unsubscribe function. Delivery defaults to every change; "commit" is accepted for symmetry with interval selections and follows the point selection's normal update delivery.

Parameters¶

Returns¶

() => void

clear¶

clear: () => void

Clears the selection and publishes the cleared state when it changed.

Returns¶

void
