Examples of org.apache.lucene.store.IndexInput.readBytes()

org.apache.lucene.store.IndexInput.readBytes()
Reads a specified number of bytes into an array at the specified offset. @param b the array to read bytes into @param offset the offset in the array to start storing bytes @param len the number of bytes to read @see IndexOutput#writeBytes(byte[],int)
