- *
- * It is not mandatory to use EvaluationException, doing so might give the following advantages:
- * - Methods can more easily be extracted, allowing for re-use.
- * - Type management (typecasting etc) is simpler because error conditions have been separated from - * intermediate calculation values.
- * - Fewer local variables are required. Local variables can have stronger types.
- * - 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.

- * - * Note - Only standard evaluation errors are represented by EvaluationException ( - * 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. - * - * @author Josh Micich - */ -public final class EvaluationException extends Exception { - private final ErrorEval _errorEval; - - public EvaluationException(ErrorEval errorEval) { - _errorEval = errorEval; - } - // some convenience factory methods - - /** #VALUE! - Wrong type of operand */ - public static EvaluationException invalidValue() { - return new EvaluationException(ErrorEval.VALUE_INVALID); - } - /** #REF! - Illegal or deleted cell reference */ - public static EvaluationException invalidRef() { - return new EvaluationException(ErrorEval.REF_INVALID); - } - /** #NUM! - Value range overflow */ - public static EvaluationException numberError() { - return new EvaluationException(ErrorEval.NUM_ERROR); - } - - public ErrorEval getErrorEval() { - return _errorEval; - } -} diff --git a/src/java/org/apache/poi/hssf/record/formula/eval/FunctionEval.java b/src/java/org/apache/poi/hssf/record/formula/eval/FunctionEval.java deleted file mode 100644 index d7be348650..0000000000 --- a/src/java/org/apache/poi/hssf/record/formula/eval/FunctionEval.java +++ /dev/null @@ -1,250 +0,0 @@ -/* ==================================================================== - Licensed to the Apache Software Foundation (ASF) under one or more - contributor license agreements.
