Package io.keikai.model.impl.sys.formula

Class FormulaRefExtractor

java.lang.Object

io.keikai.model.impl.sys.formula.FormulaRefExtractor

public final class FormulaRefExtractor
extends Object

Extracts Ref precedents from a formula string by routing through the Rust formula parser via JNI (KeikaiNative.formulaExtractRefs).

kkmodel cannot have a Maven compile-time dependency on keikai-native (that direction is reserved for the JNI bridge), so the JNI entry point is resolved via MethodHandle reflection at class load — same pattern as RustFormatBridge.

Since:

7.0.0

Parameters:

formula - the formula string (with or without leading '=')

bookName - book name to attach to each Ref

sheetName - sheet name to attach to each Ref

sheetIndex - current sheet index (passed to Rust for context)
