Add an object in the runtime store
- Import the following classes:
- Invoke RuntimeStore.put(long, String) and provide as parameters a unique long ID and the runtime object to store.
- Create a try - catch block to manage the IllegalArgumentException that put() throws if a runtime object with the same ID exists.
RuntimeStore store = RuntimeStore.getRuntimeStore(); String msg = "Some shared text"; long ID = 0x60ac754bc0867248L; try { store.put( ID, msg ); } catch(IllegalArgumentException e) { }
