Example 2 with CellValue

use of org.apache.poi.ss.usermodel.CellValue in project poi by apache.

the class BaseFormulaEvaluator method evaluateInCell.

/**
     * If cell contains formula, it evaluates the formula, and
     *  puts the formula result back into the cell, in place
     *  of the old formula.
     * Else if cell does not contain formula, this method leaves
     *  the cell unchanged.
     * Note that the same instance of HSSFCell is returned to
     * allow chained calls like:
     * <pre>
     * int evaluatedCellType = evaluator.evaluateInCell(cell).getCellType();
     * </pre>
     * Be aware that your cell value will be changed to hold the
     *  result of the formula. If you simply want the formula
     *  value computed for you, use {@link #evaluateFormulaCellEnum(Cell)}}
     * @param cell
     * @return the {@code cell} that was passed in, allowing for chained calls
