Method Detail

evaluate

public boolean evaluate(java.lang.String numericalToken,
                        java.lang.String comparison,
                        double compareWith)
                 throws java.lang.Exception

Return true if the string token evaluates true with the specified equation.

Parameters:

numericalToken - a (potentially) numerical token to process.

comparison - the comparison to make.

compareWith - the numerical term to compare with.

Returns:

true if the evaluation is true, false otherwise, for example the evaluation is not true or the token is not numerical.

Throws:

java.lang.Exception - any error.

evaluate

public boolean evaluate(double numericalValue,
                        double compareWith,
                        java.lang.String comparison)
                 throws java.lang.Exception

Return true if the string token evaluates true with the specified equation.

Parameters:

numericalValue - the numerical value to process.

compareWith - the numerical term to compare with.

comparison - the comparison to make.

Returns:

true if the evaluation is true, false otherwise, for example the evaluation is not true or the token is not numerical.

Throws:

java.lang.Exception - any error.
