Method Summary
Modifier and Type Method Description String
formatString()
Return aprintf
format string resembling"%s something(%x)"
where the%x
will be the value being guarded; the "something" should indicate what the value represents, or what will be done with it when released by Java.protected void
javaStateUnreachable(boolean nativeStateLive)
When the Java state is released or unreachable, anSPI_freeplan
call is made so the native memory is released without having to wait for release of its containing context.-

-
javaStateUnreachable
protected void javaStateUnreachable(boolean nativeStateLive)
When the Java state is released or unreachable, anSPI_freeplan
call is made so the native memory is released without having to wait for release of its containing context.- Overrides:

- Parameters:
nativeStateLive
