Module::Generic::Boolean - Boolean Representation Class
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 }
v1.1.0
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 JSON bool, i.e. true or false
true
false
The code is taken and adapted from part of JSON module.
Returns an 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
Returns the current boolean value (1 or 0) as a Module::Generic::Number object.
Returns the current boolean value (1 or 0) as a Module::Generic::Scalar object.
Returns true.
This returns a perl true value i.e. 1 or true when added into JSON
This returns a perl false value i.e. 0 or false when added into JSON
Provided with a value and this returns true if it is a Module::Generic::Boolean object
Provided with a value and this returns true if it is a Module::Generic::Boolean object and this is true.
Provided with a value and this returns true if it is a Module::Generic::Boolean object and this is false.
This is called by JSON to transform an object into json data format.
It returns \1 if true, or \0 otherwise. Those values are understood by JSON and transcoded accordingly.
