IPC::Run3::ProfReporter - base class for handling profiling data

See IPC::Run3::ProfPP and for an example subclass.

This class just notes and accumulates times; subclasses use methods like "handle_app_call", "handle_run_exit" and "handle_app_exit" to emit reports on it. The default methods for these handlers are noops.

If run from the command line, a reporter will be created and run on each logfile given as a command line parameter or on run3.out if none are given.

This allows reports to be run like:

perl -MIPC::Run3::ProfPP -e1
perl -MIPC::Run3::ProfPP -e1 foo.out bar.out

Use "-" to read from STDIN (the log file format is meant to be moderately greppable):

grep "^cvs " run3.out perl -MIPC::Run3::ProfPP -e1 -

Use --app to show only application level statistics (ie don't emit a report section for each command run).

"IPC::Run3::ProfReporter->new"
Returns a new profile reporting object.
"$reporter->handle_app_call( ... )"
"$reporter->handle_app_exit( ... )"
"$reporter->handle_run_exit( ... )"
These methods are called by the handled events (see below).
"$reporter->app_call(\@cmd, $time)"
"$reporter->app_exit($time)"
"$reporter->run_exit(@times)"
$self->app_call( $time );
my $time = $self->get_app_call_time;

Sets the time (in floating point seconds) when the application, run3(), or system() was called or exited. If no time parameter is passed, uses IPC::Run3's time routine.

Use get_...() to retrieve these values (and _accum values, too). This is a separate method to speed the execution time of the setters just a bit.
