public final class Indexer extends Object
The Indexer operates on input streams that point to class file data. Input streams do not need to be buffered, as the indexer already does this. There is also no limit to the number of class file streams the indexer can process, other than available memory.
The Indexer attempts to minimize the final memory state of the index, but to do this it must maintain additional in-process state (intern tables etc) until the index is complete.
Numerous optimizations are taken during indexing to attempt to minimize the CPU and I/O cost, however, the Java class file format was not designed for partial searching, which ultimately limits the efficiency of processing them.
Thread-Safety This class is not thread-safe can not be shared between threads. The index it produces however is thread-safe.
