`labkit.app.view.Snapshot`

Build one immutable complete visible-state snapshot.

Syntax

view = labkit.app.view.Snapshot()
view = view.value(target, value)
view = view.choices(target, choices)
view = view.limits(target, limits)
view = view.enabled(target, enabled)
view = view.visible(target, visible)
view = view.text(target, text)
view = view.filePaths(target, paths)
view = view.fileItemStatuses(target, statuses)
view = view.listSelection(target, selection)
view = view.tableCellSelection(target, selection)
view = view.tableData(target, data, Name=Value)
view = view.renderPlot(target, model, Name=Value)
view = view.workspacePage(target, Name=Value)
view = view.anchorPath(interaction, points, Name=Value)
view = view.pairedAnchors(interaction, pointSets, Name=Value)
view = view.pointSlots(interaction, value, Name=Value)
view = view.rectangle(interaction, position, Name=Value)
view = view.regionSelection(interaction, Name=Value)
view = view.interval(interaction, range, Name=Value)
view = view.scaleReference(interaction, endpoints, Name=Value)
view = view.include(fragment)

Description

View snapshot is a closed immutable operation vocabulary. One value describes the complete current visible state; Definition validates targets, capabilities, renderer references, and completeness before a runtime may reconcile it. Apps do not author patches or generic target/property setters.

Inputs

target: Nonempty Layout target ID.
value: Target value owned by the App state.
choices: Text array or cellstr of legal choices.
limits: Increasing finite two-element numeric row.
enabled: Logical scalar availability.
visible: Logical scalar visibility.
text: Scalar text.
paths: String or cell array of file paths.
statuses: Empty or one reader-facing status per file-list row.
selection: Selection value accepted by the target.
data: App-owned table, numeric array, or cell array.
model: App-owned model passed to the renderer declared by plotArea.

Options

ViewRevision: Nonnegative integer identifying the requested initial viewport. The adapter preserves user zoom while the value is unchanged and accepts renderer limits once when it changes. Default: 0.

Outputs

view: New immutable labkit.app.view.Snapshot snapshot.
fragment: Another Snapshot whose non-duplicate operations should be included in this snapshot.

Errors

labkit:app:contract:InvalidValue: An operation argument is malformed.
labkit:app:contract:DuplicateId: The same operation is supplied twice for one target.

Example

view = labkit.app.view.Snapshot();
view = view.choices("group", ["A", "B"]);
view = view.value("group", "A");
assert(isa(view, "labkit.app.view.Snapshot"))

labkit.app.Definition — Compile and launch one immutable App SDK contract.
