findInterval(options) → TimeInterval|undefined
engine/Source/Core/TimeIntervalCollection.js 279

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.

The interval at the specified index, or undefined if no interval exists as that index.

indexOf(date) → number

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
engine/Source/Core/TimeIntervalCollection.js 671

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()
engine/Source/Core/TimeIntervalCollection.js 175

Removes all intervals from the collection.

removeInterval(interval) → boolean
engine/Source/Core/TimeIntervalCollection.js 510

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