  • Class
    Description
    AreaEval
    Reference to a rectangular area of cells.
    BlankEval
    Sentinel value representing a blank cell in the formula evaluator.
    BoolEval
    Boolean value in the formula evaluator.
    ErrorEval
    Error value in the formula evaluator (e.g.
    EvaluationException
    Checked exception thrown by helper-base function implementations (such as TextFunction, MultiOperandNumericFunction) to signal an Excel error result without short-circuiting the entire evaluator.
    FreeRefFunction
    User-implementable functional interface for plugging custom formula functions into Keikai's formula engine that need access to the evaluation context (cell position, sheet) — the equivalent of POI's org.apache.poi.ss.formula.functions.FreeRefFunction.
    Function
    User-implementable interface for plugging custom formula functions into Keikai's formula engine.
    LazyRefEval
    A RefEval that defers cell-value lookup until the consumer actually asks for it (via RefEval.getInnerValueEval(int)).
    MultiOperandNumericFunction
    Base class for custom numeric functions whose arguments are accumulated into a flat double[] array.
    NotImplementedException
    Thrown to signal that a formula function is recognised by name but has no body wired in (the registry pointed to a stub or the name was routed to ELEvalFunction without a matching TLD entry).
    NumberEval
    Immutable double-precision numeric value in the formula evaluator.
    OperandResolver
    Coercion helpers for ValueEval operands.
    RefEval
    Reference to a single cell — wraps the cell's value and exposes its coordinates for functions that need them (OFFSET, INDIRECT, CELL, …).
    StringEval
    Immutable string value in the formula evaluator.
    TextFunction
    Base class for custom functions that take string-shaped arguments and want a checked-exception escape hatch.
    TwoDEval
    Two-dimensional grid of ValueEval cells.
    ValueEval
    Marker interface for all formula-engine value types.
