Field Detail

cEntries

protected int cEntries

The number of Entry objects (including synthetics) in this segment.

Note: On a JSR-133 non-compliant JVM, this value may be stale to some extent. It is only used as an internal growth statistic, so this is acceptable. On JSR-133 compliant JVMs, the segment lock under which this value is modified performs an atomic CAS which would guarantee that writes get flushed.

fContend

protected volatile boolean fContend

Are any threads contending to lock this segment?
