NodeChangedDataTreeDelta Interface
Data carried by the treeChanged event for array nodes.
To use, import via fluid-framework/alpha.
For more information about our API support guarantees, see here.
This type is "sealed," meaning that code outside of the library defining it should not implement or extend it. Future versions of this type may add members or make typing of readonly members more specific.
Signature
/** @sealed */
export interface NodeChangedDataTreeDelta
Remarks
Extends NodeChangedDataDelta: the retain ops in the delta additionally carry a subtreeChanged flag indicating whether any descendant of the retained element changed.
Properties
| Property | Alerts | Modifiers | Type | Description |
|---|---|---|---|---|
| delta | Alpha | readonly | readonly ArrayNodeTreeChangedDeltaOp[] | undefined | The sequential operations describing what changed in the array node, including subtree-change information on retain ops. |
Property Details
delta
The sequential operations describing what changed in the array node, including subtree-change information on retain ops.
For more information about our API support guarantees, see here.
Signature
readonly delta: readonly ArrayNodeTreeChangedDeltaOp[] | undefined;
Type: readonly ArrayNodeTreeChangedDeltaOp[] | undefined
Remarks
The value may be undefined when the document was updated in a way that required multiple internal change passes in a single operation (for example, a data change combined with a schema upgrade).
See ArrayNodeTreeChangedDeltaOp for op semantics.
