Method Detail

postProcessValueEval

ValueEval postProcessValueEval(OperationEvaluationContext ec,
                               ValueEval opResult,
                               boolean eval)

Callback when evaluating a formula cell.

Parameters:

ec - the evaluation context of the evaluated formula cell.

opResult - the precedent that might change the formula cell.

eval - whether this reference is an evaluated result(e.g. from INDIRECT() function(true), or directly specified in formula(false))

Returns:

the ValueEval after the dependency checking

addDependency

void addDependency(OperationEvaluationContext ec,
                   Ptg[] ptgs)

Construct formula reference dependencies.

Parameters:

ec - the evaluation context of the evaluated formula cell.

ptgs - the precedent that might change the formula cell.
