Class IndexReaderV2

java.lang.Object

org.jboss.jandex.IndexReaderImpl

org.jboss.jandex.IndexReaderV2

final class IndexReaderV2
extends IndexReaderImpl

Reads a Jandex index file and returns the saved index. See Indexer for a thorough description of how the Index data is produced.

An IndexReader loads the stream passed to it's constructor and applies the appropriate buffering. The Jandex index format is designed for efficient reading and low final memory storage.

Thread-Safety

IndexReader is not thread-safe and can not be shared between concurrent threads. The resulting index, however, is.
