IntervalIndex Interface

Collection of intervals.

Implementers of this interface will typically implement additional APIs to support efficiently querying a collection of intervals in some manner, for example: - "find all intervals with start endpoint between these two points" - "find all intervals which overlap this range" etc.

This API is provided for existing users, but is not recommended for new users.

To use, import via @fluidframework/sequence/legacy.

For more information about our API support guarantees, see here.

Signature​

export interface IntervalIndex<TInterval extends ISerializableInterval>

Type Parameters​

Parameter Constraint Description
TInterval ISerializableInterval

Methods​

Method Alerts Return Type Description
add(interval) Alpha void Adds an interval to the index.
remove(interval) Alpha void Removes an interval from the index.

Method Details​

add​

Adds an interval to the index.

This API is provided as an alpha preview and may change without notice.

To use, import via @fluidframework/sequence/alpha.

For more information about our API support guarantees, see here.

Signature​

add(interval: TInterval): void;

Remarks​

Application code should never need to invoke this method on their index for production scenarios: Fluid handles adding and removing intervals from an index in response to sequence or interval changes.

Parameters​

Parameter Type Description
interval TInterval

remove​

Removes an interval from the index.
