Instance Method Details

#attr_property(*accessors) ⇒ Object

Syntactic sugar for providing instance level attributes. Similar to attr_accessor except the value of property is set without requiring “=” syntax, e.g.

foo.propname 5        (rather than <tt>foo.attrname=5</tt>)

foo.propname            #=> 5

In other words, setting is performed by specifing an argument, getting is performed using the same method call without an argument.
