Overview

Given a string, provides an object that takes the string’s value and turns it into a method “#value?”, returning true; other methods all respond false.

Example:

greeting = Hoodoo::StringInquirer.new( 'hello' )
greeting.hello? # => true
greeting.hi?    # => false

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(method_name, *arguments) ⇒ Object (private)

Called when a String receives a message it cannot handle. This is where StringInquirer adds in its string-value-dependent “fake” boolean method. For any method name ending in “?”, returns true if the string value matches the name except for that “?”, else false. If the method name does not end in “?”, the call is passed to super.

method_name

Method name that wasn’t found in object instance.

*arguments

List of arguments passed to the method.
