isCachable

public boolean isCachable()

Description copied from class: JavaMailNugget

This method indicates whether the Nugget implementation is a cachable nugget. A cachable nugget will be instantiate only once during the lifetime of the associated Entity. The nugget instance will be reused for future requests. On the other hand, a non-cachable nugget will be instantiated every time that the getNugget() method is invoked. A Nugget implementation can be cachable only if every method is thread safe and atomic. Namely, if there are multiple threads access it at the same time, they will not interfere each other.

Specified by:

isCachable in class JavaMailNugget

Returns:

true if the Nugget implementation is cachable, false otherwise.
