Method DataRef():getData() Foundation
Reads the current value of the edit buffer and passes it to :dataLink
:getData() --> xValue
This method returns the current value from the edit buffer of an Xbase Part.
The method :getData() reads the current value in the edit buffer of an Xbase Part. When a data code block is contained in the instance variable :dataLink, the method evaluates the code block and passes the value from the edit buffer to it as the first parameter. This generally causes an assignment of the value to a memory variable or a field variable. If no code block is contained in :dataLink, :getData() behaves exactly like the method :editBuffer().
