public static <T> T nonNullOrDefault(T instance,
                                     T ifNull)

Returns the given instance if it is not null. Otherwise ifNull is returned.

Type Parameters:

T - the type of the given instance and ifNull

Parameters:

instance - the object to validate if it is no null

ifNull - the object to return if instance is null

Returns:

the given instance if it is not null. Otherwise ifNull is returned

doIfNotNull

public static <T> ObjectUtils.OrElse doIfNotNull(T instance,
                                                 Consumer<T> action)

Performs the given action consuming the given instance, granted that it is not null.

Type Parameters:

T - the type of the given instance and object to consume by the given action

Parameters:

instance - the object to consume by the given action, if it is not null

action - the Consumer invoked with the given instance

Returns:

an ObjectUtils.OrElse to allow to perform another operation if the given action was not executed

silently

instance - the object to consume by the given action, if it is not null

action - the Consumer to silently invoke with the given instance

hasLength

public static boolean hasLength(String s)

Verify if the given String is not null and is not String.isEmpty().

Parameters:

s - the String to validate if it has any length.
