Filtering

setRowFilter

$flow.setRowFilter(nodeId: string, filter: RowFilter): void

Set a row-level filter on a specific node. RowFilter can be 'all', 'connected', 'unconnected', or a custom predicate (row) => boolean.

getRowFilter

$flow.getRowFilter(nodeId: string): RowFilter

Get the current row filter for a node. Returns 'all' if none is set.

getVisibleRows

$flow.getVisibleRows(nodeId: string, schema: any[]): any[]

Apply the node's row filter to a schema array and return only the visible rows. When filter is 'connected', returns rows whose attribute ID matches an edge handle; 'unconnected' returns the inverse.

setNodeFilter

$flow.setNodeFilter(predicate: (node: FlowNode) => boolean): void

Apply a node-level filter. Nodes that fail the predicate get filtered = true (CSS-driven visibility). Emits node-filter-change.

clearNodeFilter

$flow.clearNodeFilter(): void

Remove the node filter, restoring all nodes to visible.
