Method: Oj::Doc#type

Defined in:

ext/oj/fast.c

#type(path = nil) ⇒ Object

Returns the Class of the data value at the location identified by the path or the current location if the path is nil or not provided. This method does not create the Ruby Object at the location specified so the overhead is low.

@param [String] path path to the location to get the type of if provided

Examples:

Oj::Doc.open('[1,2]') { |doc| doc.type() }	     #=> Array
Oj::Doc.open('[1,2]') { |doc| doc.type('/1') }  #=> Fixnum
