evaluateCondition

protected boolean evaluateCondition(ConditionEvaluationInterface conditionEvaluationInterface,
                                    Object[] values)

Method evaluateCondition. This method does the actual evaluation, and should be called from any implementers to figure out if the condition evaluated true or false

Parameters:

conditionEvaluationInterface -

values - the row values needed for the evaluation.

Returns:

boolean whether the condition evaluated true or false.

evaluate

public abstract Object evaluate(ConditionEvaluationInterface conditionEvaluationInterface,
                                Object[] values)

Method evaluate. This method evaluates the condition and returns the formatting to be used.

Parameters:

conditionEvaluationInterface -

values - the row values which is needed for the condition evaluation

Returns:

Object the returned formatting, or null if the condition evaluated false.
