Package io.keikaiex.formula

Class ELEvalFunction

java.lang.Object

io.keikaiex.formula.ELEvalFunction

All Implemented Interfaces:

FreeRefFunction, Serializable

public class ELEvalFunction
extends Object
implements FreeRefFunction, Serializable

Default function that delegates a Keikai formula call to a TLD-defined EL function (registered via <?taglib?> in the active ZUL).

POI removal Keikai-native rewrite — implements FreeRefFunction only (POI's separate Function interface is gone; the no-context overload is folded into the single evaluate(ValueEval[], Object) entry point).

Evaluate the user function.

Specified by:

evaluate in interface FreeRefFunction

Parameters:

args - the parsed argument values (numeric / string / boolean / error / blank Eval instances)
