destroyObject
Destroys an object. Each of the object's functions, including functions in its prototype,
is replaced with a function that throws a DeveloperError, except for the object's
isDestroyed function, which is set to a function that returns true.
The object's properties are removed with delete.
This function is used by objects that hold native resources, e.g., WebGL resources, which
need to be explicitly released. Client code calls an object's destroy function,
which then releases the native resource and calls destroyObject to put itself
in a destroyed state.
Parameters:
| Name | Type | Argument | Description |
|---|---|---|---|
object |
Object | The object to destroy. | |
message |
String |
<optional> |
The message to include in the exception that is thrown if a destroyed object's function is called. |
Example
// How a texture would destroy itself.
this.destroy = function () {
_gl.deleteTexture(_texture);
return Cesium.destroyObject(this);
};
