Methods

addSample

Adds a new sample

Parameters:

Name	Type	Description
time	JulianDate	The sample time.
value	Cartesian3	The value at the provided time.

Throws:

• DeveloperError : time is required.
• DeveloperError : value is required.

addSamples

Adds an array of samples

Parameters:

Name	Type	Description
times	Array	An array of JulianDate instances where each index is a sample time.
values	Array	The array of Cartesian3 instances, where each value corresponds to the provided times index.

Throws:

• DeveloperError : times is required.
• DeveloperError : values is required.
• DeveloperError : times and values must be the same length..

addSamplesPackedArray

Adds samples as a single packed array where each new sample is represented as a date, followed by the packed representation of the corresponding value.

Parameters:

Name	Type	Argument	Description
packedSamples	Array		The array of packed samples.
epoch	JulianDate	<optional>	If any of the dates in packedSamples are numbers, they are considered an offset from this epoch, in seconds.

Throws:

DeveloperError : packedSamples is required.

equals

Compares this property to the provided property and returns true if they are equal, false otherwise.

Parameters:

Name	Type	Argument	Description
other	Property	<optional>	The other property.

Returns:

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

getValue

Parameters:

Name	Type	Argument	Description
time	JulianDate		The time for which to retrieve the value.
result	Cartesian3	<optional>	The object to store the value into, if omitted, a new instance is created and returned.

Throws:

DeveloperError : time is required.

Returns:

Cartesian3 The modified result parameter or a new instance if the result parameter was not supplied.

getValueInReferenceFrame

Gets the value of the property at the provided time and in the provided reference frame.

Parameters:

Name	Type	Argument	Description
time	JulianDate		The time for which to retrieve the value.
referenceFrame	ReferenceFrame		The desired referenceFrame of the result.
result	Cartesian3	<optional>	The object to store the value into, if omitted, a new instance is created and returned.

Throws:

• DeveloperError : time is required.
• DeveloperError : referenceFrame is required.

Returns:

Cartesian3 The modified result parameter or a new instance if the result parameter was not supplied.
