Properties

Readonly contentChanged

contentChanged: ISignal<ICellModel, void>

A signal emitted when the content of the model changes.

executionCount

executionCount: ExecutionCount

The code cell's prompt number. Will be null if the cell has not been run.

Readonly id

id: string

A unique identifier for the cell.

Readonly isDirty

isDirty: boolean

Whether the code cell has been edited since the last run.

Readonly isDisposed

isDisposed: boolean

Test whether the object has been disposed.

Notes

This property is always safe to access.

Readonly metadata

metadata: Omit<IBaseCellMetadata, "trusted">

The metadata associated with the cell.

Notes

This is a copy of the metadata. Changing a part of it won't affect the model. As this returns a copy of all metadata, it is advised to use getMetadata to speed up the process of getting a single key.

Readonly metadataChanged

metadataChanged: ISignal<ICellModel, IMapChange<any>>

Signal emitted when cell metadata changes.

mimeType

mimeType: string

A mime type of the model.

Notes

It is never null, the default mime type is text/plain.

mimeTypeChanged

mimeTypeChanged: ISignal<CodeEditor.IModel, IChangedArgs<string, string, string>>

A signal emitted when a property changes.

Readonly outputs

outputs: IOutputAreaModel

The cell outputs.

Readonly selections

selections: IObservableMap<ITextSelection[]>

The currently selected code.

Readonly sharedModel

sharedModel: ISharedCodeCell

The code cell shared model

Readonly stateChanged

stateChanged: ISignal<ICellModel, IChangedArgs<boolean, boolean, any>>

A signal emitted when a model state changes.

trusted

trusted: boolean

Whether the cell is trusted.

Readonly type

type: "code"

The type of the cell.

Notes

This is a read-only property.

Methods

clearExecution

deleteMetadata

dispose

  • dispose(): void

  • Dispose of the resources held by the object.

    Notes

    If the object's dispose method is called more than once, all calls made after the first will be a no-op.

    Undefined Behavior

    It is undefined behavior to use any functionality of the object after it has been disposed unless otherwise explicitly noted.

    Returns void

getMetadata

setMetadata

toJSON
