/**
* Annotation for method declarations, which denotes that this method will not cause allocations
* that are visible from source code. Compilers or runtimes can still introduce opportunities for
* allocation to occur that might result in garbage collection.
*
* <p>Be careful using this annotation. It should be used sparingly, typically only for methods
* called within inner loops or user interface event handlers. Misuse will likely lead to
* decreased performance and significantly more complex code.
