A
GeometryUpdater for polylines.
Clients do not normally create this class directly, but instead rely on DataSourceDisplay.

Gets a value indicating if the geometry is clamped to the ground.
Returns false if polylines on terrain is not supported.
readonly classificationTypeProperty : Property
Gets or sets the
ClassificationType Property specifying if this geometry will classify terrain, 3D Tiles, or both when on the ground.
readonly depthFailMaterialProperty : MaterialProperty

Methods
createFillGeometryInstance(time) → GeometryInstance
Creates the geometry instance which represents the fill of the geometry.
| Name | Type | Description |
|---|---|---|
time |
JulianDate | The time to use when retrieving initial attribute values. |
Returns:
The geometry instance representing the filled portion of the geometry.
Throws:
-
DeveloperError : This instance does not represent a filled geometry.
createOutlineGeometryInstance(time) → GeometryInstance
Creates the geometry instance which represents the outline of the geometry.
| Name | Type | Description |
|---|---|---|
time |
JulianDate | The time to use when retrieving initial attribute values. |
Returns:
The geometry instance representing the outline portion of the geometry.
Throws:
-
DeveloperError : This instance does not represent an outlined geometry.
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.
Returns true if this object was destroyed; otherwise, false.
Returns:
True if this object was destroyed; otherwise, false.
Checks if the geometry is filled at the provided time.
| Name | Type | Description |
|---|---|---|
time |
JulianDate | The time for which to retrieve visibility. |
Returns:
true if geometry is filled at the provided time, false otherwise.
Checks if the geometry is outlined at the provided time.
| Name | Type | Description |
|---|---|---|
time |
JulianDate | The time for which to retrieve visibility. |
Returns:
true if geometry is outlined at the provided time, false otherwise.
