Instance Attribute Details

#markup_type ⇒ Object (readonly)

this class is just a wrapper to Array. I want to treat this as a stack of objects for the workbook DSL to reference. I need to push an object onto the stack, reference it using the ‘current’ method, and pop it off the stack when I’m done.
