C capable as well. This is a subclass of L in which the underlying array has its data stored in a line-oriented-format: that is, every element ends in a C<"\n">, with the possible exception of the final element. This makes C I more efficient; if you plan to do line-oriented reading/printing, you want this class. The C method will enforce this rule, so you can print arbitrary data to the line-array: it will break the data at newlines appropriately. See L for full usage and warnings. =cut #------------------------------ # # getline # # Instance method, override. # Return the next line, or undef on end of data. # Can safely be called in an array context. # Currently, lines are delimited by "\n". # sub getline { my $self = shift; if (!defined $/) { return join( '', $self->_getlines_for_newlines ); } elsif ($/ eq "\n") { if (!*$self->{Pos}) { ### full line... return *$self->{AR}[*$self->{Str}++]; } else { ### partial line... my $partial = substr(*$self->{AR}[*$self->{Str}++], *$self->{Pos}); *$self->{Pos} = 0; return $partial; } } else { croak 'unsupported $/: must be "\n" or undef'; } } #------------------------------ # # getlines # # Instance method, override. # Return an array comprised of the remaining lines, or () on end of data. # Must be called in an array context. # Currently, lines are delimited by "\n". # sub getlines { my $self = shift; wantarray or croak("can't call getlines in scalar context!"); if ((defined $/) and ($/ eq "\n")) { return $self->_getlines_for_newlines(@_); } else { ### slow but steady return $self->SUPER::getlines(@_); } } #------------------------------ # # _getl
