new Cesium.PolylineGeometryUpdater(entity, scene)
engine/Source/DataSources/PolylineGeometryUpdater.js 71

A GeometryUpdater for polylines. Clients do not normally create this class directly, but instead rely on DataSourceDisplay.
参数名称 类型 描述信息
entity Entity The entity containing the geometry to be visualized.
scene Scene The scene where visualization is taking place.

方法

createFillGeometryInstance(time) → GeometryInstance
engine/Source/DataSources/PolylineGeometryUpdater.js 361

Creates the geometry instance which represents the fill of the geometry.
参数名称 类型 描述信息
time JulianDate The time to use when retrieving initial attribute values.
返回值:
The geometry instance representing the filled portion of the geometry.
Throws:
  • DeveloperError : This instance does not represent a filled geometry.

createOutlineGeometryInstance(time) → GeometryInstance
engine/Source/DataSources/PolylineGeometryUpdater.js 448

Creates the geometry instance which represents the outline of the geometry.
参数名称 类型 描述信息
time JulianDate The time to use when retrieving initial attribute values.
返回值:
The geometry instance representing the outline portion of the geometry.
Throws:
  • DeveloperError : This instance does not represent an outlined geometry.

destroy()
engine/Source/DataSources/PolylineGeometryUpdater.js 472

Destroys and resources used by the object. Once an object is destroyed, it should not be used.
Throws:
  • DeveloperError : This object was destroyed, i.e., destroy() was called.

isDestroyed() → boolean
engine/Source/DataSources/PolylineGeometryUpdater.js 463

Returns true if this object was destroyed; otherwise, false.
返回值:
True if this object was destroyed; otherwise, false.

isFilled(time) → boolean
engine/Source/DataSources/PolylineGeometryUpdater.js 344

Checks if the geometry is filled at the provided time.
参数名称 类型 描述信息
time JulianDate The time for which to retrieve visibility.
返回值:
true if geometry is filled at the provided time, false otherwise.

isOutlineVisible(time) → boolean
engine/Source/DataSources/PolylineGeometryUpdater.js 334

Checks if the geometry is outlined at the provided time.
参数名称 类型 描述信息
time JulianDate The time for which to retrieve visibility.
返回值:
true if geometry is outlined at the provided time, false otherwise.
