参数
Object with the following properties:
参数
A Clock instance that is used when determining the value for the time dimension. Required when <code>options.times</code> is specified.
参数
TimeIntervalCollection with its <code>data</code> property being an object containing time dynamic dimension and their values.
参数
A function that will request imagery tiles.
参数
A function that will be called when all imagery tiles need to be reloaded.
属性
clock
clock:
Clock
Gets or sets a clock that is used to get keep the time used for time dynamic parameters.
times
times:
TimeIntervalCollection
Gets or sets a time interval collection.
currentInterval
currentInterval:

Gets the current interval.
方法
getFromCache()
getFromCache(
x:number,y:number,level:number,request?:Request):Promise<HTMLImageElement> |undefined
Gets the tile from the cache if its available.
参数
x
number
The tile X coordinate.
y
number
The tile Y coordinate.
level
number
The tile level.
request?
The request object. Intended for internal use only.
返回
Promise<HTMLImageElement> | undefined
A promise for the image that will resolve when the image is available, or undefined if the tile is not in the cache.
checkApproachingInterval()
checkApproachingInterval(
x:number,y:number,level:number,request?:Request):void
Checks if the next interval is approaching and will start preload the tile if necessary. Otherwise it will just add the tile to a list to preload when we approach the next interval.
参数
x
number
The tile X coordinate.
y
number
The tile Y coordinate.
level
number
