public interface IsSingleton
Used for defining if a given class is singleton or not. If the class is a singleton, then a single instance will be
shared (and hence should be treated as immutable and be used in a thread-safe manner).
This interface is not implemented as a marker interface (i.e., it's necessary to read
isSingleton()
instead
of instanceof(IsSingleton)). This allows for subclasses to have a singleton status different from a parent
and for objects to have this value dynamically changed.
Camel component are very often singleton based, only a few components are not.-
