class FalseClass

Parent:: Object

The global value false is the only instance of class FalseClass and represents a logically false value in boolean expressions. The class provides operators allowing false to participate correctly in logical expressions.

Public Instance Methods

false & object → false

nil & object → false

Source

static VALUE
false_and(VALUE obj, VALUE obj2)
{
    return Qfalse;
}

Returns false:

false & true       # => false
false & Object.new # => false

Argument object is evaluated:

false & raise # Raises RuntimeError.

true === other → true or false

false === other → true or false

nil === other → true or false

Source

#define case_equal rb_equal

Returns true or false.

Like Object#==, if object is an instance of Object (and not an instance of one of its many subclasses).

This method is commonly overridden by those subclasses, to provide meaningful semantics in case statements.

false ^ object → true or false

nil ^ object → true or false

Source

#define false_xor true_and

Returns false if object is nil or false, true otherwise:

nil ^ nil        # => false
nil ^ false      # => false
nil ^ Object.new # => true

false | object → true or false

nil | object → true or false

Source

#define false_or true_and

Returns false if object is nil or false, true otherwise:

nil | nil        # => false
nil | false      # => false
nil | Object.new # => true

inspect

Alias for: to_s

to_s → "false"

Source

VALUE
rb_false_to_s(VALUE obj)
{
    return rb_cFalseClass_to_s;
}

The string representation of false is “false”.

Also aliased as: inspect
