class Hocon::ConfigValueFactory
  ConfigImpl = Hocon::Impl::ConfigImpl

#
 # Creates a {@link ConfigValue} from a plain value, which may be
 # a <code>Boolean</code>, <code>Number</code>, <code>String</code>,
 # <code>Hash</code>, or <code>nil</code>. A
 # <code>Hash</code> must be a <code>Hash</code> from String to more values
 # that can be supplied to <code>from_any_ref()</code>. A <code>Hash</code>
 # will become a {@link ConfigObject} and an <code>Array</code> will become a
 # {@link ConfigList}.
 #
 # 
 # In a <code>Hash</code> passed to <code>from_any_ref()</code>, the map's keys
 # are plain keys, not path expressions. So if your <code>Hash</code> has a
 # key "foo.bar" then you will get one object with a key called "foo.bar",
 # rather than an object with a key "foo" containing another object with a
 # key "bar".
 #
 # 
 # The origin_description will be used to set the origin() field on the
 # ConfigValue. It should normally be the name of the file the values came
 # from, or something short describing the value such as "default settings".
 # The origin_description is prefixed to error messages so users can tell
 # where problematic values are coming from.
 #
 # 
 # Supplying the result of ConfigValue.unwrapped() to this function is
 # guaranteed to work and should give you back a ConfigValue that matches
 # the one you unwrapped. The re-wrapped ConfigValue will lose some
 # information that was present in the original such as its origin, but it
 # will have matching values.
 #
 # 
 # If you pass in a <code>ConfigValue</code> to this
 # function, it will be returned unmodified. (The
 # <code>origin_description</code> will be ignored in this
 # case.)
 #
 # 
 # This function throws if you supply a value that cannot be converted to a
 # ConfigValue, but supplying such a value is a bug in your program, so you
 # should never handle the exception. Just fix your program (or report a bug
 # against this library).
 #
 # @param object
 # object to convert to ConfigValue
 # @param origin_description
 # name of origin file or brief description of what the value is
 # @return a new value
 #
 def self.from_any_ref(object, origin_description = nil)
 if object.is_a?(Hash)
 from_map(object, origin_description)
 else
 ConfigImpl.from_any_ref(object, origin_description)
 end
 end

#
 # See the {@link #from_any_ref(Object,String)} documentation for details
 #
 # 
 # See also {@link ConfigFactory#parse_map(Map)} which interprets the keys in
 # the map as path expressions.
 #
 # @param values map from keys to plain ruby values
 # @return a new {@link ConfigObject}
 #
