Method Detail

retain

public static <T> T retain(T msg)

Try to call ReferenceCounted.retain() if the specified message implements ReferenceCounted. If the specified message doesn't implement ReferenceCounted, this method does nothing.

retain

public static <T> T retain(T msg,
           int increment)

Try to call ReferenceCounted.retain() if the specified message implements ReferenceCounted. If the specified message doesn't implement ReferenceCounted, this method does nothing.

release

public static boolean release(Object msg)

Try to call ReferenceCounted.release() if the specified message implements ReferenceCounted. If the specified message doesn't implement ReferenceCounted, this method does nothing.

release

public static boolean release(Object msg,
              int decrement)

Try to call ReferenceCounted.release() if the specified message implements ReferenceCounted. If the specified message doesn't implement ReferenceCounted, this method does nothing.

releaseLater

public static <T> T releaseLater(T msg)

Schedules the specified object to be released when the caller thread terminates. Note that this operation is intended to simplify reference counting of ephemeral objects during unit tests. Do not use it beyond the intended use case.

releaseLater

public static <T> T releaseLater(T msg,
                 int decrement)

Schedules the specified object to be released when the caller thread terminates. Note that this operation is intended to simplify reference counting of ephemeral objects during unit tests. Do not use it beyond the intended use case.
