SPVM::Bool - A Boolean value as An Object

Description

The Bool class in SPVM represents a boolean value as an object.

Usage

  use Bool;
  
  my $true = Bool->TRUE;
  my $false = Bool->FALSE;
  
  my $true_value = $true->value;
  my $false_value = $false->value;

Details

This class is immutable.

This class is automatically loaded.

The Bool object is different behavior in bool context.

If the "value" field is 1, it is evaluated as true.

  if (Bool->TRUE) {
    # Run
  }

If the "value" field is 0, it is evaluated as false.

  if (Bool->FALSE) {
    # Not run
  }

The true keyword is the same as Bool->TRUE.

  if (true) {
    # Run
  }

The false keyword is the same as Bool->FALSE.

  if (false) {
    # Not run
  }
