[Pharo-project] Fwd: break point

In CodeHolder apparently there is support for breakpoint. Does anybody know how this works? Stef

toggleBreakOnEntry "Install or uninstall a halt-on-entry breakpoint"

| selectedMethod | self selectedClassOrMetaClass isNil ifTrue:[^self]. selectedMethod := self selectedClassOrMetaClass >> self selectedMessageName. selectedMethod hasBreakpoint ifTrue: [BreakpointManager unInstall: selectedMethod] ifFalse: [BreakpointManager installInClass: self selectedClassOrMetaClass selector: self selectedMessageName].
