NAME ^

JSON::DWIW::Boolean - Return a true or false value when evaluated in boolean context -- to be used with JSON::DWIW->encode() to explicitly specify a boolean value.`

SYNOPSIS ^

 use JSON::DWIW;
 my $val1 = JSON::DWIW->true;
 my $val2 = JSON::DWIW->false;
 
 # or
 
 use JSON::DWIW::Boolean;
 my $val1 = JSON::DWIW::Boolean->new(1); # true value
 my $val2 = JSON::DWIW::Boolean->new(0); # false value

DESCRIPTION ^

This module is not intended to be used directly. It is intended to be used as part of JSON::DWIW to specify that a true or false value should be output when converting to JSON, since Perl does not have explicit values for true and false.

Overloading is used, so if a JSON::DWIW::Boolean object is evaluated in boolean context, it will evaluate to 1 or 0, depending on whether the object was initialized to true or false.

METHODS ^

new($val)

Returns an object initialized with $val as its boolean value.

true()

Class method that returns a new object initialized to a true value.

false()

Class method that returns a new object initialized to a false value.
