- All Implemented Interfaces:
- ErrorAware, LogTarget
- public class MemoryTarget
- extends AbstractTarget
Output LogEvents into an buffer in memory.
At a later stage these LogEvents can be forwarded or
pushed to another target. This pushing is triggered
when buffer is full, the priority of a LogEvent reaches a threshold
or when another class calls the push method.
This is based on specification of MemoryHandler in Logging JSR47.
