Package io.keikai.range.formula

Class OperandResolver

java.lang.Object

io.keikai.range.formula.OperandResolver

public final class OperandResolver
extends Object

Coercion helpers for ValueEval operands. Mirror of Apache POI's org.apache.poi.ss.formula.eval.OperandResolver — only the methods Keikai actually uses are implemented (single-value extraction + scalar coercion to String / int / double).

POI removal Keikai-native helper. Lets the kkex formula-bridge code (ELEval / ELEvalFunction) coerce custom-function arguments without pulling POI in.

Since:

7.0.0

Method Summary

Modifier and Type	Method	Description
static double	coerceValueToDouble(ValueEval v)	Coerce v to a double.
static int	coerceValueToInt(ValueEval v)	Coerce v to an int (Math.floor — matches POI's OperandResolver).
static String	coerceValueToString(ValueEval v)	Coerce v to a string.
static ValueEval	getSingleValue(ValueEval arg, int rowIndex, int colIndex)	Returns a single scalar from arg.

Method Details

getSingleValue

public static ValueEval getSingleValue(ValueEval arg,
 int rowIndex,
 int colIndex)
                                throws EvaluationException

Returns a single scalar from arg. For area / ref types this picks the element at (rowIndex, colIndex) (matching POI's implicit-intersection behaviour for single-cell input). For scalar types arg is returned as-is.

Throws:

EvaluationException - with #VALUE! for multi-cell areas that do not intersect the formula cell row/col.

coerceValueToString

public static String coerceValueToString(ValueEval v)
                                  throws EvaluationException

Coerce v to a string. Errors propagate as EvaluationException.

Throws:

EvaluationException

coerceValueToDouble

public static double coerceValueToDouble(ValueEval v)
                                  throws EvaluationException

Coerce v to a double.

Throws:

EvaluationException

coerceValueToInt

public static int coerceValueToInt(ValueEval v)
                            throws EvaluationException

Coerce v to an int (Math.floor — matches POI's OperandResolver).

Throws:

EvaluationException
