hi all: I'm new to dev these days I'm reading the source code in the index package and I was confused. there are classes with suffix PerThread such as DocFieldProcessorPerThread, DocInverterPerThread, TermsHashPerThread, FreqProxTermWriterPerThread.
in this mailing-list, I was told that they are multithreaded. however, there are some difficulties for me to understand! I see no sign that they inherited from the Thread , or implement the Runnable, or something else?? how do they map to the OS thread?? thanks ^_^
