CanvasFeatureGateMixin

Auto-generated from the @jbrowse/mobx-state-tree model in the source — see the developer guide for concepts. Provided by the canvas plugin. View source.

The density axis of the region-too-large gate, composed after MultiRegionDisplayMixin. A display opts in by composing this and calling commitGateMeasurements from its fetch's onComplete.

Volatiles

MemberDescription
densityStatsPerRegion
ObservableMap<number, RegionDensityStats>		Per-region feature counts, so the verdict is a live max at the current bpPerPx.

Getters

MemberDescription
gateEnabled
boolean		types.compose resolves a collision to the later argument, so this mixin must follow the one declaring the byte-gate opt-in.
visibleFeatureDensityPerPx
number		Density at the debounced coarseBpPerPx, so the verdict shares the layout cadence.
maxFeatureDensity
number | undefined		Undefined when the axis may not act.
densityTooLarge
boolean

Methods

MemberDescription
observedMaxDensity
(bpPerPx: number) => number

Actions

MemberDescription
setDensityStats
(displayedRegionIndex: number, stats: RegionDensityStats) => void
clearGateMeasurements
() => void		RegionTooLargeMixin's hook: the density axis drops its counts on the trigger that drops the byte estimate, so one gate cannot hold two measurements of two different files.
commitGateMeasurements
(measurements: RegionGateMeasurement[], issued: GateFetchState) => void
