=encoding utf8 =head1 NAME Module::Generic::Boolean - Boolean Representation Class =head1 SYNOPSIS my $bool = Module::Generic::Boolean->true; # or my $bool = Module::Generic::Boolean::true; # Now I have a Module::Generic::Boolean object # Returns 1 if( $bool ) { # Do something } my $hash = { name => 'John Doe', active => $bool, }; # Converting to json print( JSON->new->encode( $hash ), "\n" ); # Would result in { name: "Jogn Doe", active: true } =head1 VERSION v1.1.0 =head1 DESCRIPTION This a class/package to represent boolean value and make sure they are recognised interchangeably as perl boolean, i.e. 1 or 0, or as L<JSON> bool, i.e. C<true> or C<false> The code is taken and adapted from part of L<JSON> module. =head1 METHODS =head2 as_array Returns an L<Module::Generic::Array> object with the current boolean value as its only entry. my $true = Module::Generic::Boolean->true; my $a = $true->as_array; say $a->[0]; # 1 =head2 as_number Returns the current boolean value (1 or 0) as a L<Module::Generic::Number> object. =head2 as_scalar Returns the current boolean value (1 or 0) as a L<Module::Generic::Scalar> object. =head2 defined Returns true. =head2 true This returns a perl true value i.e. 1 or C<true> when added into L<JSON> =head2 false This returns a perl false value i.e. 0 or C<false> when added into L<JSON> =head2 is_bool Provided with a value and this returns true if it is a L<Module::Generic::Boolean> object =head2 is_true Provided with a value and this returns true if it is a L<Module::Generic::Boolean> object and this is true. =head2 is_false Provided with a value and this returns true if it is a L<Module::Generic::Boolean> object and this is false. =head2 TO_JSON This is called by L<JSON> to transform an object into json data format. It returns C<\1> if true, or C<\0> otherwise. Those values are understood by L<JSON> and transcoded accordingly. =head1 AUTHOR Jacques Deguest E<lt>F<jack@deguest.jp>E<gt> =head1 COPYRIGHT & LICENSE Copyright (c) 2000-2020 DEGUEST Pte. Ltd.
