NAME

OP::Scalar - Scalar object class

DESCRIPTION

Extends OP::Object to handle Perl scalar values as OP Objects.

INHERITANCE

This class inherits additional class and object methods from the following packages:

OP::Class > OP::Object > OP::Scalar

SYNOPSIS

use OP::Scalar;

{
  my $scalar = OP::Scalar->new("Hello World");
  print "$scalar\n";

  # Hello World
}

{
  my $scalar = OP::Scalar->new(5);
  my $result = $scalar + $scalar;
  print "$scalar + $scalar = $result\n";

  # 5 + 5 = 10
}

PUBLIC CLASS METHODS

• $class->new($scalar)

  Instantiate a new OP::Scalar. Accepts an optional scalar value as a prototype object

  Usage is cited in the SYNOPSIS section of this document.

PUBLIC INSTANCE METHODS

• $self->get()

  Abstract method, not implemented.

  Delegates to superclass if class method.

• $self->set( )

  Abstract method, not implemented.

  Delegates to superclass if class method.

• $self->size()

  Object wrapper for Perl's built-in length() function. Functionally the same as length(@$ref).

  my $scalar = OP::Scalar->new("Testing");
  
  my $size = $scalar->size(); # returns 7

• $self->isEmpty()

  Returns a true value if self contains no values, otherwise false.

  my $array = OP::Scalar->new("");
  
  if ( $self->isEmpty() ) {
    print "Is Empty\n";
  }
  
  # Expected Output:
  #
  # Is Empty
  #

• $self->clear()

  Truncate self to zero length.

• $self->value()

  Returns the actual de-referenced value of self. Same as ${ $self };

• $self->sprint()

  Overrides superclass to sprint the actual de-referenced value of self.

• $self->say()

  Prints the de-referenced value of self with a line break at the end.
