@searsuite/sear-render-engine

DI token for resolving the abstract data engine singleton.

Restricts registered state and view changes to the owning runtime after setup.

Retrieves a plugin-owned data value.

ReturnsRegistered value, or void 0 when absent.

Reads registration metadata for a plugin-owned data value.

ReturnsRegistration metadata, or void 0 when the key is not registered.

Lists fields registered for one named data view.

ReturnsField names in registration order.

Resolves a transport-safe plugin-key string to the registered key object.

PluginKey construction intentionally creates a unique identity, so remote transports must resolve the received string back to this registry's existing key before creating a transaction for PluginManager.

ReturnsRegistered PluginKey, or void 0 when no state owner has that key.

Reports whether a plugin state has been registered with this engine.

ReturnsTrue when the key owns a DataEngine-visible state value.

Initializes engine-owned registries or projections.

Reads one field from a named data view without materializing the whole view.

ReturnsField value, or void 0 when the field is unregistered or unavailable.

Registers a plugin-owned data value.

Registers one field selector for a named data view.

ThrowsDataViewFieldDuplicateError when another owner already registered the same field in the same view.

Replaces a plugin-owned data value.

Creates a duplicate data view field error.

Stable machine-readable code for duplicate data view field registrations.

Creates a render context for a registered type.

ReturnsNew render context instance.

Registers a render-context creator.

Creates a RenderEngine instance.

DI token for resolving RenderEngine.

Initializes RenderEngine.

Discard pixel-cache reuse before the next render.

Marks a region or the current scene for rendering on the next frame.

Renders RenderEngine scene output.

Resizes the render target and invalidates dependent frame state.

Updates the view scale.

Initializes sheet data projections.

Constructs the sheet data plugin.

SheetDataPlugin owns the persisted sheet-data export module.

Sheet data reacts to cell changes and row/column structure edits from any command owner.

Sheet data transactions share the registered MatrixOT algebra.

Sheet data is state-only; duplicate render/event depth diagnostics do not apply.

Document-state export contribution for persisted sheet cells.

Stable plugin key shared by all sheet data plugin instances.

DI token for resolving the sheet data plugin.

Applies sheet-data operations to the persisted cell matrix.

ReturnsUpdated plugin state, or null when the transaction has no relevant operations.

Sheet data has no render-time configuration.

Contributes this owner's cell state to atomic range moves.

Publishes a live read-only projection for consumers that do not need an export snapshot.

Registers the sheet data matrix for commands, rendering, and collaboration.

Sheet data does not render scene nodes directly.

ReturnsAn empty node list.

Creates a SheetRenderEngine instance.

Applies a transaction to SheetRenderEngine state.

Returns the layer.

Returns the stage.

Initializes SheetRenderEngine.

Drops retained screen content so the next frame repaints it.

Marks a region or the current scene for rendering on the next frame.

Handles the click lifecycle event.

Handles the scroll lifecycle event.

Renders SheetRenderEngine scene output.

Resizes every canvas layer and invalidates scroll optimization buffers.

Updates the view scale.

Returns the configured fallback used for absent sparse entries, if one exists.

Computes and returns the cumulative dimension map.

The dimensions map stores the cumulative sum of all dimension values up to each column. For example, if dimensions are [10, 20, 30], the map is [10, 30, 60]. This allows O(1) lookups of boundaries without recalculating sums.

Result is cached until the matrix is modified. Cache is automatically invalidated when rows/columns are added, deleted, or modified.

ReturnsArray where element i contains the sum of dimensions 0..i Time Complexity: O(rows * cols) on first call or after modification, O(1) for cached result

const matrix = new DimensionsCSRMatrix(...);
const map = matrix.getDimensionsMap(); // [10, 30, 60]

Retrieves an item from the matrix at the specified row and column.

ReturnsThe item at the specified position or null if not present.

Field selectors contributed by the registered state to named data views.

Field name written into the named view.

When false, missing owner state or void field values do not make the containing view unavailable.

Reads the field value from the current owner state.

Named read model that receives the selected field.

Main sheet matrix containing persisted cell values.

Formula source text for formula cells; calculated results live in formula plugin state.

Array evaluation mode used when the formula was entered.

Cell type identifier owned by the cell type catalog.

Raw value whose shape is owned by the cell type.

Creates a render engine for one document editor instance.

DI token for resolving DocRenderEngine.

Returns the screen strategy mode used by the last render pass, if it painted.

Initializes DocRenderEngine.

Invalidates the off-screen body cache used by the screen strategy.

Marks one document-world rectangle dirty for the next dirty pass.

Runs the configured document render strategies over the current scene graph.

Resizes all Doc render layers and invalidates screen-cache reuse.

Supplies one layout-shift raster-copy plan for the next screen render pass.

Updates the viewport model used by subsequent render frames.

Updates the view scale on every render strategy context.

Editable content rectangle inside the viewport.

Visible viewport height in host-view units.

Visible viewport width in host-view units.

Constructs a CSRMatrix instance.

Copies stored cell payloads as well as sparse indexes.
