U:RDoc::AnyMethod[iI"const_missing:ETI"Module#const_missing;TF:publico:RDoc::Markup::Document:@parts[
o:RDoc::Markup::Paragraph;	[I"BInvoked when a reference is made to an undefined constant in ;FI"G<i>mod</i>. It is passed a symbol for the undefined constant, and ;FI"Ireturns a value to be used for that constant. For example, consider:;Fo:RDoc::Markup::BlankLine�o:RDoc::Markup::Verbatim;	[
I"!def Foo.const_missing(name)
;TI"1  name # return the constant name as Symbol
;TI"	end
;TI"
;TI"CFoo::UNDEFINED_CONST    #=> :UNDEFINED_CONST: symbol returned

;	[
I"OAs the example above shows, +const_missing+ is not required to create the ;FI"Mmissing constant in <i>mod</i>, though that is often a side-effect. The ;FI"Scaller gets its return value when triggered. If the constant is also defined, ;FI"Sfurther lookups won't hit +const_missing+ and will return the value stored in ;FI"Mthe constant as usual. Otherwise, +const_missing+ will be invoked again.;F@o;
;	[I"MIn the next example, when a reference is made to an undefined constant, ;FI"Q+const_missing+ attempts to load a file whose path is the lowercase version ;FI"Qof the constant name (thus class <code>Fred</code> is assumed to be in file ;FI"Q<code>fred.rb</code>). If defined as a side-effect of loading the file, the ;FI"Rmethod returns the value stored in the constant. This implements an autoload ;FI"Rfeature similar to Kernel#autoload and Module#autoload, though it differs in ;FI"important ways.;F@o;;	[I"$def Object.const_missing(name)
