The properties of this object and its sub-objects represent a point in time state at the time the operation was applied. They will not take into any future modifications performed to the underlying sequence and merge tree.

Signature:

export declare abstract class SequenceEvent<TOperation extends MergeTreeDeltaOperationTypes = MergeTreeDeltaOperationTypes>
