class FalseClass

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 click to toggle source

nil & object → false

Returns false:

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

Argument object is evaluated:

false & raise # Raises RuntimeError.

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

true === other → true or false click to toggle source

false === other → true or false

nil === other → true or false

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.

#define case_equal rb_equal

false ^ object → true or false click to toggle source

nil ^ object → true or false

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

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

#define false_xor true_and

inspect()

The string representation of false is “false”.

Alias for: to_s

to_s → "false" click to toggle source

The string representation of false is “false”.

VALUE
rb_false_to_s(VALUE obj)
{
    return rb_cFalseClass_to_s;
}

Also aliased as: inspect

false | object → true or false click to toggle source

nil | object → true or false

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

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