val string_of_class_type : ?complete:bool -> Types.class_type -> string

This function returns a string representing a Types.class_type.

parameter complete
indicates if we must print complete signatures or just object end. Default is false.

Get a string from a text.

val string_of_info : info -> string

Get a string from an info structure.

val string_of_type : Type.t_type -> string

returns
a string to describe the given type.

returns
an empty structure if there was a syntax error. TODO: change this

val info_string_of_info : info -> string
