Method Detail

test

public <T> boolean test(EMultipleConditionCombinationType combinationType,
                        String customExpression,
                        Iterable<T> items,
                        Function<T,Map.Entry<String,Boolean>> evaluator)

Combines the given conditions via the combination type.

Type Parameters:

T - Type of the items.

Parameters:

combinationType - How to combine the individual results.

customExpression - Custom combination expression for EMultipleConditionCombinationType.CUSTOM.

items - A list of items representing the individual conditions.

evaluator - Takes a single condition and evaluates it. The key must be the name of the condition for EMultipleConditionCombinationType.CUSTOM.

Returns:

The result of combining the individual results via the given combination type.

test

public boolean test(EMultipleConditionCombinationType combinationType,
