addInterval(interval, dataComparer)

Core/TimeIntervalCollection.js 308

Adds an interval to the collection, merging intervals that contain the same data and splitting intervals of different data as needed in order to maintain a non-overlapping collection. The data in the new interval takes precedence over any existing intervals in the collection.

Name	Type	Description
interval	TimeInterval	The interval to add.

Returns:

true if the collection contains the specified date, false otherwise.

equals(right, dataComparer) → Boolean

The data for the interval containing the specified date, or undefined if no such interval exists.

findInterval(options) → TimeInterval

Core/TimeIntervalCollection.js 280

Returns the first interval in the collection that matches the specified parameters. All parameters are optional and undefined parameters are treated as a don't care condition.

Name	Type	Description
options	Object	optional Object with the following properties: Name Type Description start JulianDate optional The start time of the interval. stop JulianDate optional The stop time of the interval. isStartIncluded Boolean optional true if options.start is included in the interval, false otherwise. isStopIncluded Boolean optional true if options.stop is included in the interval, false otherwise.

Finds and returns the index of the interval in the collection that contains the specified date.

Name	Type	Description
date	JulianDate	The date to search for.

Returns:

The index of the interval that contains the specified date, if no such interval exists, it returns a negative number which is the bitwise complement of the index of the next interval that starts after the date, or if no interval starts after the specified date, the bitwise complement of the length of the collection.

intersect(other, dataComparer, mergeCallback) → TimeIntervalCollection

Core/TimeIntervalCollection.js 602

Creates a new instance that is the intersection of this collection and the provided collection.

Name	Type	Description
other	TimeIntervalCollection	The collection to intersect with.
dataComparer	TimeInterval~DataComparer	optional A function which compares the data of the two intervals. If omitted, reference equality is used.
mergeCallback	TimeInterval~MergeCallback	optional A function which merges the data of the two intervals. If omitted, the data from the left interval will be used.

Returns:

A new TimeIntervalCollection which is the intersection of this collection and the provided collection.

removeAll()

Core/TimeIntervalCollection.js 190

Removes all intervals from the collection.

removeInterval(interval)

Core/TimeIntervalCollection.js 456

Removes the specified interval from this interval collection, creating a hole over the specified interval. The data property of the input interval is ignored.
