NAME Safe::Caller - Control code execution based upon caller() SYNOPSIS package abc; use Safe::Caller; $caller = Safe::Caller->new; a(); sub a { b() } sub b { if ($caller->called_from_subroutine('abc::a')) { # do stuff } print $caller->{subroutine}->(); } DESCRIPTION CONSTRUCTOR new $caller = Safe::Caller->new(1); Providing how many frames to go back while running perlfunc is optional. By default (if no suitable value is provided) 1 will be assumed. The default will be shared among all accessors and verification routines; the accessors may optionally accept a frame as argument, whereas verification routines (`called_from_*()') don't. METHODS called_from_package Checks whether the current sub was called within the given package. $caller->called_from_package('Package'); Returns true on success, false on failure. called_from_filename Checks whether the current sub was called within the given filename. $caller->called_from_filename('file'); Returns true on success, false on failure. called_from_line Checks whether the current sub was called on the given line. $caller->called_from_line(42); Returns true on success, false on failure. called_from_subroutine Checks whether the current sub was called by the given subroutine. $caller->called_from_subroutine('Package::sub'); Returns true on success, false on failure. ACCESSORS $caller->{package}->(); $caller->{filename}->(); $caller->{line}->(); $caller->{subroutine}->(); $caller->{hasargs}->(); $caller->{wantarray}->(); $caller->{evaltext}->(); $caller->{is_require}->(); $caller->{hints}->(); $caller->{bitmask}->(); See perlfunc for the values they are supposed to return.
