Method: Module#constants

Defined in:
variable.c

#constants(inherit = true) ⇒ Array

Returns an array of the names of the constants accessible in mod. This includes the names of constants in any included modules (example at start of section), unless the inherit parameter is set to false.

The implementation makes no guarantees about the order in which the constants are yielded.

IO.constants.include?(:SYNC)        #=> true
IO.constants(false).include?(:SYNC) #=> false

Also see Module#const_defined?.

Returns:
