fields) is semantically immutable, although the field values may

90

change. For example, an agent may update the location line number

91

to reflect the actual line where the breakpoint was set, but this

Bu Sun Kim

2020-05-20 12:08:20 -0700

doesn't change the breakpoint semantics.

Sai Cheemalapati

93

94

This means that an agent does not need to check if a breakpoint has changed

95

when it encounters the same breakpoint on a successive call.

96

Moreover, an agent should remember the breakpoints that are completed

97

until the controller removes them from the active list to avoid

98

setting those breakpoints again.
