Resources (codenameone-core 7.0.96 API)

java.lang.Object
- com.codename1.ui.util.Resources

```
public class Resources
extends Object
```
Loads resources from the binary resource file generated by the Codename One Designer. A resource is loaded entirely into memory since random file access is not supported in all platforms. Any other approach would be inefficient. This means that memory must be made available to accommodate the resource file.
