module Jsonify
# Provides a set of functions for creating JsonValues from Ruby objects.
module Generate
class << self
# Coerces the given value into a JsonValue (or subclass), String, or Number.
#
# The coercion rules are based on the type (class) of the value as follows:
# - +JsonValue+ => no coercion
# - +String+ => no coercion
# - +Numeric+ => no coercion
# - +TrueClass+ => JsonTrue ( true )
# - +FalseClass+=> JsonFalse ( false )
# - +NilClass+ => JsonNull ( null )
# - +Array+ => JsonArray ( [1,2,3] )
# - +Hash+ => JsonObject ( <code>{"\a":1,\"b\":2}</code> )
# - +else+ => #to_s
#
# @param val value to coerce into a JsonValue.
