## org.apache.poi.ss.formula.eval
Class RefEvalBase

    java.lang.Object
      org.apache.poi.ss.formula.eval.RefEvalBase

All Implemented Interfaces:
  RefEval, ValueEval, SheetRange

Direct Known Subclasses:
  LazyRefEval

    public abstract class RefEvalBase

extends java.lang.Object
implements RefEval

Common base class for implementors of `RefEval`

Constructor Summary
`protected` | `RefEvalBase(int onlySheetIndex, int rowIndex, int columnIndex)`
`protected` | `RefEvalBase(int firstSheetIndex, int lastSheetIndex, int rowIndex, int columnIndex)`
`protected` | `RefEvalBase(SheetRange sheetRange, int rowIndex, int columnIndex)`

Method Summary
`int` | `getColumn()` returns the zero based column index.
`int` | `getFirstSheetIndex()` returns the first sheet index this applies to
`int` | `getLastSheetIndex()` returns the last sheet index this applies to, which will be the same as the first for a 2D and many 3D references
`int` | `getNumberOfSheets()` returns the number of sheets this applies to
`int` | `getRow()` returns the zero based row index.
