DebuggableSignal

Trigger JS debugger when signal is evaluating its initial value (if when passes at that time)

Log when signal is evaluating its initial value (if when passes at that time)

Execute fn when signal is evaluating its currentValueFromParent. This is typically triggered when evaluating signal's initial value onStart, as well as on subsequent re-starts when the signal is syncing its value to the parent's new current value.

Trigger JS debugger for emitted events and errors if when passes Note: for Signals this also triggers onStart (with the current value at the time)

Trigger JS debugger for emitted errors (but not events) if when passes Note: for Signals this also triggers onStart (if current value is an error)

Trigger JS debugger for emitted events (but not errors) if when passes Note: for Signals this also triggers onStart (if current value is not an error)

Trigger JS debugger when the observable stops

Log emitted events and errors if when condition passes, using dom.console.log if useJsLogger is true. Note: for Signals this also triggers on start (with the current value at the time)

Log emitted errors (but not regular events) if when condition passes Note: for Signals this also triggers onStart (if current value is an error)

Log emitted events (but not errors) if when condition passes, using dom.console.log if useJsLogger is true. Note: for Signals this also triggers onStart (if current value is not an error)

Execute fn on every emitted event or error Note: for Signals this also triggers onStart (with the current value at the time)

Return the observable's topoRank. This does not affect the observable in any way.

Create a new observable that listens to the original, and set the displayName of the new observable. This is different from setDisplayName.

If you say stream.debugWithName("foo").debugLog(), the displayName used by the logger will be "foo" verbatim, whereas if you say stream.setDisplayName("foo").debugLog(), the logger's displayName will be "foo|Debug" – with a suffix – to differentiate it from the "foo" displayName of stream itself.
