- hotLocation T
- The field that may be manipulated by multiple threads.
- applyChange FuncT, T
- A function that receives the unchanged value and returns the changed value.
- T
- The type of data.
Boolean if the location's value is changed by applying the result of the
applyChange function;
if the location's value remained the same because the last invocation of
applyChange returned the existing value.
