Package com.bigdata.jsr166 Description

Utility classes related derived from JSR 166. Classes in this package MAY have been modified to support specific tasks in bigdata. In particular, new constructors may provide a means to declare a Lock to the class such that the same lock can be shared with another class. This pattern breaks encapsulation of the JSR class design decisions with regard to locks and signals, but it enables patterns which are otherwise not possible without creating deadlock through holding an outer lock while waiting on the inner lock within the JSR class. This sort of pattern/problem exists in the BlockingBuffer and ChunkedRunningQuery classes. By using modified versions of the JSR classes we can work around the problem using an appropriate pattern.
