Methods

broadcastKernelSelected

broadcastKernelSelected(runtime: Runtime): Promise<void>
Broadcasts kernel selection to all registered webviews. Used when a runtime is selected that should apply to multiple documents.
Parameters
- runtime: Runtime
  Selected runtime to broadcast
Returns Promise<void>
- Defined in src/services/bridges/kernelBridge.ts:304

broadcastKernelTerminated

broadcastKernelTerminated(): Promise<void>
Broadcasts kernel termination to all registered webviews. Used when a runtime is terminated that affects multiple documents.

Returns Promise<void>
- Defined in src/services/bridges/kernelBridge.ts:326

connectWebviewDocument

connectWebviewDocument(uri: Uri, runtime: Runtime): Promise<void>
Connects a webview document (notebook or lexical) to a runtime. Sends runtime information to the webview for ServiceManager creation.
Parameters
- uri: Uri
  Document URI
- runtime: Runtime
  Selected runtime
Returns Promise<void>
- Defined in src/services/bridges/kernelBridge.ts:90

detectNotebookType

detectNotebookType(uri: Uri): "webview" | "native"
Detects the type of notebook (native vs webview).
Parameters
- uri: Uri
  Notebook URI
Returns "webview" | "native"
"webview" for Datalayer notebooks, "native" for others
- Defined in src/services/bridges/kernelBridge.ts:164

dispose

dispose(): void
