方法
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.
使用示例:
p = p && p.destroy();
参考:
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.
返回值:
true
if this object was destroyed; otherwise, false
.
