15.4.3 Tracing slot access

The Slots > Trace submenu provides four options. When inspecting a CLOS object, code which accesses the selected slot may be traced using these commands.

    Break on Read causes a break to the debugger if the slot is accessed for read, either by a defined accessor or by slot-value .

    Break on Write causes a break to the debugger if the slot is accessed for write, either by a defined accessor or by slot-value .

    Break on Access causes a break to the debugger if the slot is accessed for read or write, either by a defined accessor or by slot-value .

    Untrace turns off tracing on the selected slot.

The Object > Trace submenu provides the same four options, but these commands control the tracing of all the slots in the object.
