    interface InputSignalWithTransform {}

InputSignalWithTransform represents a special Signal for a directive/component input with a transform function.

Signal inputs with transforms capture an extra generic for their transform write type. Transforms can expand the accepted bound values for an input while ensuring value retrievals of the signal input are still matching the generic input type.

          class MyDir {  disabled = input(false, {    transform: (v: string|boolean) => convertToBoolean(v),  }); // InputSignalWithTransform<boolean, string|boolean>  click() {    this.disabled() // always returns a `boolean`.  }}
