Required methods

Returns true if the function source hash was added to the coverage map (even if it had already been added, for this instance). Returns false only if -Z instrument-coverage is not enabled (a coverage map is not being generated).

Returns true if the counter was added to the coverage map; false if -Z instrument-coverage is not enabled (a coverage map is not being generated).

Returns true if the expression was added to the coverage map; false if -Z instrument-coverage is not enabled (a coverage map is not being generated).

Returns true if the region was added to the coverage map; false if -Z instrument-coverage is not enabled (a coverage map is not being generated).
