public XEvaluator()

Method Details

isForce

public boolean isForce()

Whether to force re-evaluation of sub-equations.

setForce

public void setForce(boolean force)

Whether to force re-evaluation of sub-equations. If the force parameter is true will always use the equation. If force is false then it only uses the equation is the variable does not have a valid value.

visitVar

public Object visitVar(Node node)
                throws EvaluationException

Evaluates a variable, it will calculate the value using variables equation if necessary. If the force parameter is true will always use the equation. If force is false then it only uses the equation is the variable does not have a valid value.

Overrides:

visitVar in class FastEvaluator

Throws:

EvaluationException
