KBE3D / KBCore / Cesium / CompositeProperty

类: CompositeProperty

A Property which is defined by a TimeIntervalCollection, where the data property of each TimeInterval is another Property instance which is evaluated at the provided time.

示例

const constantProperty = ...;
const sampledProperty = ...;

//Create a composite property from two previously defined properties
//where the property is valid on August 1st, 2012 and uses a constant
//property for the first half of the day and a sampled property for the
//remaining half.
const composite = new Cesium.CompositeProperty();
composite.intervals.addInterval(Cesium.TimeInterval.fromIso8601({
    iso8601 : '2012-08-01T00:00:00.00Z/2012-08-01T12:00:00.00Z',
    data : constantProperty
}));
composite.intervals.addInterval(Cesium.TimeInterval.fromIso8601({
    iso8601 : '2012-08-01T12:00:00.00Z/2012-08-02T00:00:00.00Z',
    isStartIncluded : false,
    isStopIncluded : false,
    data : sampledProperty
}));

属性

isConstant

readonly isConstant: boolean

Gets a value indicating if this property is constant. A property is considered constant if getValue always returns the same result for the current definition.

---

definitionChanged

readonly definitionChanged: Event

Gets the event that is raised whenever the definition of this property changes. The definition is changed whenever setValue is called with data different than the current value.

---

intervals

intervals: TimeIntervalCollection

Gets the interval collection.

方法

getValue()

getValue(time?: JulianDate, result?: any): any

Gets the value of the property at the provided time.

参数

time?

JulianDate

The time for which to retrieve the value. If omitted, the current system time is used.

result?

any

The object to store the value into, if omitted, a new instance is created and returned.

返回

any

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

equals(other?: Property): boolean

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