* RefEval is the super interface for Ref2D and Ref3DEval. Basically a RefEval
|
|
* impl should contain reference to the original ReferencePtg or Ref3DPtg as
|
|
* well as the final "value" resulting from the evaluation of the cell
|
|
* reference. Thus if the HSSFCell has type CELL_TYPE_NUMERIC, the contained
|
|
* value object should be of type NumberEval; if cell type is CELL_TYPE_STRING,
|
|
* contained value object should be of type StringEval
