Modify the internal code-coverage-data object.
A code-coverage-data object.
clear-code-coverage clears the internal code-coverage-data object, which means removing all the files from it, so that their counters are not accessible anymore. Note that it does not actually remove the counters from the code.
reset-code-coverage resets all the counters in the internal code-coverage-data object to 0.
restore-code-coverage-data sets the counters of all files that appear in both the internal code coverage data and the argument code-coverage-data to the counters in the code-coverage-data argument. All these files need to have the same code coverage code, that is they must be based on the same binary file.
error controls what happens for files that do not have the same code coverage code. Value
:warn means warn and continue,
nil means quietly skip it, and
t means signal an error.
restore-code-coverage-data never restores a file with no matching code coverage code. The default value of error is
The value of result indicates whether there was an internal code-coverage-data object when the function was called.
