Example
var constantProperty = ...;
var 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.
var composite = new bmgl.CompositeProperty();

(readonly) definitionChanged : Event
獲取每當此屬性的定義更改時引發(fā)的事件。每當使用與當前值不同的數(shù)據(jù)調(diào)用setvalue時，定義就會更改。
intervals : TimeIntervalCollection
獲取間隔集合。
(readonly) isConstant : Boolean
獲取一個值，該值指示此屬性是否為常量。如果getValue總是為當前定義返回相同的結(jié)果，則將屬性視為常量。
Methods
equals(other) → {Boolean}
將此屬性與提供的屬性進行比較，如果相等，則返回
true，否則返回false。
Parameters:
獲取所提供時間的屬性值。
Parameters:
result
(Object)
將值存儲到的對象（如果省略），將創(chuàng)建并返回新實例。
