Class protocol:

 label

Answers a short label - for UI

 isUsefulFor: aCodeView

this filters useful services.
Redefined to return true for myself - not for subclasses

Instance protocol:

 breakpointAtLine: line

return the breakpoint at line (may be disabled) or nil, if there is none

 breakpoints

Fixup breakpoint positions

 removeAllBreakpoints

 setOrToggleBreakpointAtLine: line

if true, setting a single breakpoint in a method will create

 update: aspect with: param from: sender

ATTENTION: I thought that fetching the methodHolder once in initialize would

 updateBreakPointsFor: aMethod

Transcript show:'update breakpoints for method: '; showCR:aMethod.

 updateCurrentMethod

codeView methodHolder class == BlockValue ifTrue:[self breakPoint:#cg].

 buttonMultiPress: button x: x y: y in: view

(comment from inherited method)
Handles an event in given view (a subview of codeView).
If the method returns true, it has eaten the event and it will not be processed
by the view.

 buttonPress: button x: x y: y in: view

now disabled: need a double click (like in other editors);
also this allows toggling breakpoints even if there are ther service-annotations

 keyPress: key x: x y: y in: view

Handles an event in given view (a subview of codeView).
If the method returns true, it has eaten the event and it will not be processed
by the view.

 linesDeletedFrom: start to: end

 linesInsertedFrom: start to: end

 helpTextAtLine: ignoredLineNr

 fetchMethodHolder

redefinable in subclasses, which do not have a codeView2/methodHolder

 initialize

(comment from inherited method)
Invoked when a new instance is created.

 fixupBreakpointPositions

 moveBreakpointsAfterLine: line by: delta

Note that position will be fixed up in BreakpointService>>breakpoints

 recompile

recompile the current method for changed breakpoints

 canCreateOrToggleBreakpointAtLine: lineOrNilForAnywhere

is it possible to place a breakpoint here and now?

 hasBreakpoints

 drawLine: lineNo in: view atX: x y: yBaseline width: w height: hFont ascent: aFont from: startCol to: endColOrNil with: fg and: bg

Called by both gutterView and textView (well, not yet) to
allow services to draw custom things on text view.
Ask JV what the args means if unsure (I'm lazy to document
them, now it is just an experiment...)
