IPC::Run3::ProfReporter(3)				User Contributed Perl Documentation				IPC::Run3::ProfReporter(3)

NAME
IPC::Run3::ProfReporter - base class for handling profiling data SYNOPSIS
DESCRIPTION
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). METHODS
"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 = $self->get_app_call_time; Sets the time (in floating point seconds) when the application, run3(), or system() was called or exited. If no time parameter is passed, uses IPC::Run3's time routine. Use get_...() to retrieve these values (and _accum values, too). This is a separate method to speed the execution time of the setters just a bit. "$reporter->get_run_count()" "$reporter->get_app_call_time()" "$reporter->get_app_exit_time()" "$reporter->get_app_cmd()" "$reporter->get_app_time()" "$reporter->get_app_cumulative_time()" "$reporter->get_run_call_time()" "$reporter->get_run_exit_time()" "$reporter->get_run_time()" "$reporter->get_run_cumulative_time()" "$reporter->get_sys_call_time()" "$reporter->get_sys_exit_time()" "$reporter->get_sys_time()" "$reporter->get_sys_cumulative_time()" "$reporter->get_run_cmd()" LIMITATIONS
