Package org.springframework.core.task
Interface TaskDecorator
- Functional Interface:
- This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
A callback interface for a decorator to be applied to any
Runnable
about to be executed.
Note that such a decorator is not necessarily being applied to the
user-supplied Runnable/Callable but rather to the actual
execution callback (which may be a wrapper around the user-supplied task).
The primary use case is to set some execution context around the task's invocation, or to provide some monitoring/statistics for task execution.
NOTE: Exception handling in TaskDecorator implementations
may be limited. Specifically in case of a Future-based operation,
the exposed Runnable will be a wrapper which does not propagate
any exceptions from its run method.
