fieldsReader
public PointsReader fieldsReader(SegmentReadState state) throws java.io.IOException
Description copied from class:PointsFormat
Reads a segment. NOTE: by the time this call returns, it must hold open any files it will need to use; else, those files may be deleted. Additionally, required files may be deleted during the execution of this call before there is a chance to open them. Under these circumstances an IOException should be thrown by the implementation. IOExceptions are expected and will automatically cause a retry of the segment opening logic with the newly revised segments.- Specified by:
fieldsReader
in classPointsFormat
- Throws:
java.io.IOException
