TimeInterval

// Construct an Timeinterval closed on one end with a Color payload.
var interval = new Cesium.TimeInterval(Cesium.JulianDate.fromTotalDays(1000), Cesium.JulianDate.fromTotalDays(1001), true, false, Cesium.Color.WHITE);

Members

data

The data associated with this interval.

isEmpty

Indicates if the interval is empty.

isStartIncluded

Indicates if start is included in the interval or not.

isStopIncluded

Indicates if stop is included in the interval or not.

start

The start time of the interval.

stop

The stop time of the interval.

<static> EMPTY

An empty interval.

Methods

clone

Creates a copy of this TimeInterval.

Returns:

A new TimeInterval that is equal to this interval.

contains

Returns true if this interval contains the specified date.

Parameters:

Name	Type	Description
date	JulianDate	The date to check for.

Returns:

Boolean true if the TimeInterval contains the specified date, false otherwise.

equals

Compares this TimeInterval against the provided TimeInterval componentwise and returns true if they are equal, false otherwise.

Parameters:

Name	Type	Argument	Description
right	TimeInterval	<optional>	The right hand side Cartesian.
dataComparer	Function	<optional>	A function which compares the data of the two intervals. If ommitted, reference equality is used.

Returns:

Boolean true if they are equal, false otherwise.

equalsEpsilon

Compares this TimeInterval against the provided TimeInterval componentwise and returns true if they are within the provided epsilon, false otherwise.

Parameters:

Name	Type	Argument	Description
right	TimeInterval	<optional>	The right hand side Cartesian.
epsilon	Number		The epsilon to use for equality testing.
dataComparer	Function	<optional>	A function which compares the data of the two intervals. If ommitted, reference equality is used.

Returns:

Boolean true if they are within the provided epsilon, false otherwise.

<static> equals

Compares the provided TimeIntervals and returns true if they are equal, false otherwise.

Parameters:

Name	Type	Argument	Description
left	TimeInterval	<optional>	The first interval.
right	TimeInterval	<optional>	The second interval.
dataComparer	Function	<optional>	A function which compares the data of the two intervals. If ommitted, reference equality is used.

Returns:

Boolean true if left and right are equal, false otherwise.

<static> equalsEpsilon

Compares the provided TimeIntervals componentwise and returns true if they are within the provided epsilon, false otherwise.

Parameters:

Name	Type	Argument	Description
left	TimeInterval	<optional>	The first TimeInterval.
right	TimeInterval	<optional>	The second TimeInterval.
epsilon	Number		The epsilon to use for equality testing.
dataComparer	Function	<optional>	A function which compares the data of the two intervals. If ommitted, reference equality is used.

Returns:

Boolean true if left and right are within the provided epsilon, false otherwise.

<static> fromIso8601

Creates an immutable TimeInterval from an ISO 8601 interval string.

Parameters:

Name	Type	Argument	Default	Description
iso8601String	String			A valid ISO8601 interval.
isStartIncluded	Boolean	<optional>	true	true if the start date is included in the interval, false otherwise.
isStopIncluded	Boolean	<optional>	true	true if the stop date is included in the interval, false otherwise.
data	Object	<optional>		The data associated with this interval.

Returns:

TimeInterval The new TimeInterval instance or undefined if an invalid ISO8601 string is provided.

Example

// Construct an open Timeinterval with a Cartesian data payload.
var interval = Cesium.TimeInterval.fromIso8601('2012-03-15T11:02:24.55Z/2012-03-15T12:28:24.03Z', false, false, new Cesium.Cartesian3(1,2,3));

<static> prototype.intersect

Computes an interval which is the intersection of this interval with another while also providing a means to merge the data of the two intervals.

Parameters:

Name	Type	Argument	Description
other	TimeInterval		The interval to intersect with this interval.
mergeCallback	Function	<optional>	A callback which takes the data property from both intervals as input and merges it into a single new value. If the callback is undefined, this will intersect the two intervals and return the new interval with the data from this interval.

Returns:

TimeInterval The new TimeInterval that is the intersection of the two intervals, with its data representing the merge of the data in the two existing intervals.
