Methods

staticCesium.DataSourceDisplay.defaultVisualizersCallback()
DataSources/DataSourceDisplay.js 123

Gets or sets the default function which creates an array of visualizers used for visualization. By default, this function uses all standard visualizers.

destroy()
DataSources/DataSourceDisplay.js 212

Destroys the WebGL resources held by this object. Destroying an object allows for deterministic release of WebGL resources, instead of relying on the garbage collector to destroy this object.

Once an object is destroyed, it should not be used; calling any function other than isDestroyed will result in a DeveloperError exception. Therefore, assign the return value (undefined) to the object as done in the example.
Throws:
  • DeveloperError : This object was destroyed, i.e., destroy() was called.
Example:
dataSourceDisplay = dataSourceDisplay.destroy();
See:

isDestroyed() → Boolean
DataSources/DataSourceDisplay.js 192

Returns true if this object was destroyed; otherwise, false.

If this object was destroyed, it should not be used; calling any function other than isDestroyed will result in a DeveloperError exception.
Returns:
True if this object was destroyed; otherwise, false.
See:

update(time) → Boolean
DataSources/DataSourceDisplay.js 238

Updates the display to the provided time.
Name Type Description
time JulianDate The simulation time.
Returns:
True if all data sources are ready to be displayed, false otherwise.
