NAME
Sprog::Mixin::SlurpFile - a 'mixin' class for gears reading a file at a timeSYNOPSIS
use base qw( Sprog::Mixin::SlurpFile Sprog::Gear ); sub file_data { my($self, $data, $filename) = @_; # do stuff with $data and call $self->msg_out }
DESCRIPTION
This mixin is for use by gears which use a 'pipe' style of input connector but only want to process a whole file at a time. It defines a "data" method which buffers input until the "file_end" event, at which point it calls your module's "file_data" method and passes all the accumulated data.METHODS
file_start ( filename )
Resets the buffer and then propagates the "file_start" event.data ( chunk )
Adds the chunk of input into a buffer.file_end ( filename )
Passes the accumulated data from the buffer to the "file_data" method and then propagates the "file_start" event.A class that uses this mixin is expected to implement a "file_data" method. It should accept two arguments: the data and the filename.
