* This class is used to simplify error handling logic <i>within</i> operator and function
|
||||||
|
* implementations. Note - <tt>OperationEval.evaluate()</tt> and <tt>Function.evaluate()</tt>
|
||||||
|
* method signatures do not throw this exception so it cannot propagate outside.<p/>
|
||||||
|
*
|
||||||
|
* Here is an example coded without <tt>EvaluationException</tt>, to show how it can help:
|
||||||
|
* <pre>
|
||||||
|
* public Eval evaluate(Eval[] args, int srcRow, short srcCol) {
|
||||||
|
* // ...
|
||||||
|
* Eval arg0 = args[0];
|
||||||
|
* if(arg0 instanceof ErrorEval) {
|
||||||
|
* return arg0;
|
||||||
|
* }
|
||||||
|
* if(!(arg0 instanceof AreaEval)) {
|
||||||
|
* return ErrorEval.VALUE_INVALID;
|
||||||
|
* }
|
||||||
|
* double temp = 0;
|
||||||
|
* AreaEval area = (AreaEval)arg0;
|
||||||
|
* ValueEval[] values = area.getValues();
|
||||||
|
* for (int i = 0; i < values.length; i++) {
|
||||||
|
* ValueEval ve = values[i];
|
||||||
|
* if(ve instanceof ErrorEval) {
|
||||||
|
* return ve;
|
||||||
|
* }
|

|
* if(!(ve instanceof NumericValueEval)) {
|

|
||||||
|
* }
|
||||||
|
* // ...
|
||||||
|
* }
|
||||||
|
* </pre>
|
||||||
|
* In this example, if any error is encountered while processing the arguments, an error is
|
||||||
|
* returned immediately. This code is difficult to refactor due to all the points where errors
|
||||||
|
* are returned.<br/>
|
||||||
|
* Using <tt>EvaluationException</tt> allows the error returning code to be consolidated to one
|
||||||
|
* place.<p/>
|
||||||
|
* <pre>
|
||||||
|
* public Eval evaluate(Eval[] args, int srcRow, short srcCol) {

|
||||||
|
* }
|
||||||
|
* if (arg0 instanceof AreaEval) {
|
||||||
|
* return (AreaEval) arg0;
|

|
||||||
|
* </pre>
|
||||||
|
* It is not mandatory to use EvaluationException, doing so might give the following advantages:<br/>
|
||||||
|
* - Methods can more easily be extracted, allowing for re-use.<br/>
|
||||||
|
* - Type management (typecasting etc) is simpler because error conditions have been separated from
|
||||||
|
* intermediate calculation values.<br/>
|
||||||
|
* - Fewer local variables are required. Local variables can have stronger types.<br/>
|
||||||
|
* - It is easier to mimic common Excel error handling behaviour (exit upon encountering first
|
||||||
|
* error), because exceptions conveniently propagate up the call stack regardless of execution
|
||||||
|
* points or the number of levels of nested calls.<p/>
|
||||||
|
*
|
||||||
|
* <b>Note</b> - Only standard evaluation errors are represented by <tt>EvaluationException</tt> (
|
||||||
|
* i.e. conditions expected to be encountered when evaluating arbitrary Excel formulas). Conditions
|
||||||
|
* that could never occur in an Excel spreadsheet should result in runtime exceptions. Care should
|
||||||
|
* be taken to not translate any POI internal error into an Excel evaluation error code.

|

|
* both selection from a single row area and a single column area in the same formula.
|

|
*
|

|

|
*
|
||||||
|
* If the formula "=1000+A1:B1+D2:D3" is put into the 9 cells from A2 to C4, the spreadsheet
|
||||||
|
* will look like this:
|
||||||
|
*
|
||||||
|
* <table border="1" cellpadding="1" cellspacing="1" summary="sample spreadsheet">

|
* Note that the row area (A1:B1) does not include column C and the column area (D2:D3) does
|
||||||
|
* not include row 4, so the values in C1(=25) and D4(=400) are not accessible to the formula
|
||||||
|
* as written, but in the 4 cells A2:B3, the row and column selection works ok.<p/>
|

|
||||||
|
* multi-column areas can be useful.<p/>
|
||||||

*

|
||||||
|
* hence this method <b>can</b> throw a 'circular reference' EvaluationException. Note that
|
||||||
|
* this method does not attempt to detect cycles. Every cell in the specified Area <tt>ae</tt>

||||||

* has already been evaluated prior to this method call. Any cell (or cell<b>s</b>) part of

* <tt>ae</tt> that would incur a cyclic reference error if selected by this method, will
|
||||||
|
* already have the value <t>ErrorEval.CIRCULAR_REF_ERROR</tt> upon entry to this method. It
|
||||||
|
* is assumed logic exists elsewhere to produce this behaviour.

|
*
|

|

Circular references are not dealt with directly here, but it is worth noting some issues.
|

|
|

|
ANY one of the return statements in this method could return a cell that is identical
|
||||||
|
to the one immediately being evaluated. The evaluating cell is identified by srcCellRow,
|
||||||
|
srcCellRow AND sheet. The sheet is not available in any nearby calling method, so that's
|
||||||
|
one reason why circular references are not easy to detect here. (The sheet of the returned
|
||||||
|
cell can be obtained from ae if it is an Area3DEval.)
|
||||||
|
|
||||||
|
Another reason there's little value in attempting to detect circular references here is
|
||||||
|
that only direct circular references could be detected. If the cycle involved two or more
|
||||||
|
cells this method could not detect it.
|
||||||
|
|
||||||
|
Logic to detect evaluation cycles of all kinds has been coded in EvaluationCycleDetector
|

|
(and FormulaEvaluator).
