Wait class

Immutable object to keep track of boolean flags that indicate if some process is in progress (the user is "waiting").

The flags and flag-references can be any immutable object. They must be immutable to make sure Wait is also immutable.

Use it in Redux store states, like this:

  • To add a flag: state.copy(wait: state.wait.add(flag: myFlag));
  • To remove a flag: state.copy(wait: state.wait.remove(flag: myFlag));
  • To clear all flags: state.copy(wait: state.wait.clear());

If can also use have a flag with a reference, like this:

  • To add a flag with reference: state.copy(wait: state.wait.add(flag: myFlag, ref:MyRef));
  • To remove a flag with reference: state.copy(wait: state.wait.remove(flag: myFlag, ref:MyRef));
  • To clear all references for a flag: state.copy(wait: state.wait.clear(flag: myFlag));

In the ViewModel, you can check the flags/references, like this:

  • To check if there is any waiting: state.wait.isWaiting
  • To check if a specific flag is waiting: state.wait.isWaitingFor(myFlag);
  • To check if a specific flag/reference is waiting: state.wait.isWaitingFor(myFlag, ref: myRef);
