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