Click on the
Line
item in the breadcrumb bar to get back to the list of all
Line
instances.
Click on a single instance and then click the arrow icon on that row. This will show you
the history of this object. There are two events: when the
Line
was created and when it
was destroyed. You can select an event row to see the stack trace that resulted in the event
in the extended detail area.

Allocations
instrument. First, click the
Stop
button
in the top left corner of the
Instruments
window. (The options we are going to configure
must be set before
Instruments
begins monitoring the application.)
