Public Instance Methods
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.
Source
#define case_equal rb_equal
Returns true or false.
Like Object#==, if other 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.
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
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
Source
VALUE
rb_false_to_s(VALUE obj)
{
return rb_cFalseClass_to_s;
}
The string representation of false is “false”.
