Method Detail

getFactoryType

static Class<?> getFactoryType(Class<? extends PooledObjectFactory> factoryClass)

Identifies the concrete type of object that an object factory creates.

Parameters:

factoryClass - The factory to examine

Returns:

the type of object the factory creates

isPositive

static boolean isPositive(Duration delay)

max

static Instant max(Instant a,
                   Instant b)

Returns the greater of two Instant values. That is, the result is the argument closer to the value of Instant.MAX. If the arguments have the same value, the result is that same value.

Parameters:

a - an argument.

b - another argument.

Returns:

the larger of a and b.

min

static Instant min(Instant a,
                   Instant b)

Returns the smaller of two Instant values. That is, the result is the argument closer to the value of Instant.MIN. If the arguments have the same value, the result is that same value.

Parameters:

a - an argument.

b - another argument.

Returns:

the smaller of a and b.

toChronoUnit

static ChronoUnit toChronoUnit(TimeUnit timeUnit)

Converts a TimeUnit to a ChronoUnit.

Parameters:

timeUnit - A TimeUnit.

Returns:

The corresponding ChronoUnit.

nonNull

static Duration nonNull(Duration value,
                        Duration defaultValue)

Returns a non-null duration, value if non-null, otherwise defaultValue.

Parameters:

value - May be null.

defaultValue - May not be null/

Returns:

value if non-null, otherwise defaultValue.

toDuration

static Duration toDuration(long amount,
                           TimeUnit timeUnit)

Converts am amount and TimeUnit into a Duration.

Parameters:

amount - the amount of the duration, measured in terms of the unit, positive or negative

timeUnit - the unit that the duration is measured in, must have an exact duration, not null

Returns:

a Duration.
