sealed trait Pulse[+P] extends AnyRef
Pulse that stores a current value and can also indicate a potentially change to an updated value. A pulse may indicate that no current value has been set yet but updates must always contain a value.

- def filter(p: (P) => Boolean): Pulse[P]
If the pulse indicates a change: Applies a filter function to the updated value of the pulse.
If the pulse indicates a change: Applies a filter function to the updated value of the pulse. Based on the filter function, the updated value is retained or an empty pulse is returned. If the pulse doesn't indicate a change: Returns an empty pulse indicating no change.
- p
Filter function to be applied to the updated pulse value
- returns
A pulse with the updated pulse value if the filter function returns true, an empty pulse otherwise
- def flatMap[Q](f: (P) => Pulse[Q]): Pulse[Q]
If the pulse indicates a change: Applies a function to the updated value.
If the pulse indicates a change: Applies a function to the updated value. The function has to return a new pulse that is returned by this function. If the pulse doesn't indicate a change: Returns an empty pulse indicating no change.
- Q
Value type of the pulse returned by the applied function
- f
Function to be applied on the updated pulse value
- returns
Pulse returned by the applied function or an empty pulse if there is no updated value

- def map[Q](f: (P) => Q): Pulse[Q]
If the pulse indicates a change: Applies a function to the updated value of the pulse and returns a new pulse indicating a change to this updated value.
If the pulse indicates a change: Applies a function to the updated value of the pulse and returns a new pulse indicating a change to this updated value. If the pulse doesn't indicate a change: Returns an empty pulse indicating no change.
- Q
Result type of the applied function
- f
Function to be applied on the updated pulse value
- returns
Pulse indicating the update performed by the applied function or an empty pulse if there is no updated value
