public static final java.lang.String SYSTEM_PROPERTY_TRACK_REUSABLE_BUFFERS
Deprecated.System property that is checked to see if recycled buffers (seeBufferRecycler

getBufferRecycler
@Deprecated public static BufferRecycler getBufferRecycler()
Deprecated.Since 2.16 should useRecyclerPool
abstraction instead of calling static methods of this classMain accessor to call for accessing possibly recycledBufferRecycler
instance.- Returns:
BufferRecycler
to use
-
releaseBuffers
public static int releaseBuffers()
Deprecated.Specialized method that will release all recycledBufferRecycler
if (and only if) recycler tracking has been enabled (seeSYSTEM_PROPERTY_TRACK_REUSABLE_BUFFERS
). This method is usually called on shutdown of the container like Application Server to ensure that no references are reachable viaThreadLocal
s as this may cause unintentional retention of sizable amounts of memory. It may also be called regularly if GC for some reason does not clear upSoftReference
s aggressively enough.- Returns:
- Number of buffers released, if tracking enabled (zero or more); -1 if tracking not enabled.
- Since:
- 2.9.6

JsonStringEncoder
instance to use.
