Method Detail

attributeEquals

@Nonnull
public static Predicate<Event> attributeEquals(String name,
                                                        @Nullable
                                                        Object value)

Matches events which have the specified value for a given attribute. If the specified value is null, the predicate returns true iff the event has a null value for that attribute, which includes not having any value for that attribute.

Parameters:

name - the name of the attribute to check

value - the expected value, compared with Object.equals

Returns:

a Predicate which returns true for events which have matching values for the specified attribute, and false for all others

level

@Nonnull
public static Predicate<Event> level(EventLevel... levels)

Matches events which have any of the specified levels. If no levels are provided, the predicate will always return false.

Parameters:

levels - the levels to compare against

Returns:

a Predicate which returns true for events with one of the specified levels, and false for all others

type

@Nonnull
public static Predicate<Event> type(EventType type)

Matches events which have the specified type.

Parameters:

type - the type to compare against

Returns:

a Predicate which returns true for events whose keys match the provided EventType, and false for all others
