Interface AQHttpLogReader

All Superinterfaces:

AQDataReader, Closeable

public interface AQHttpLogReader
extends AQDataReader

An object implementing this interface, available via aqua.io.newHttpLogReader(), facilitates reading of Apache web server access log files.

This helper interface makes no assumptions as to the log format (which depends on the specific server configuration). A AQDataSet produced by this interface contains the data present in the log, minus square brackets and quotes found in the original log.

Method Summary

AQDataSet	read() Sequentially reads the input log into an in-memory data set.
void	setFile(String filename) Sets the input file name
void	setFirstLineContainsColumnNames(boolean contains) Determines whether first call to AQDataReader.readNextRow() should return column names set previously by setLogFormat(String).
void	setLogFormat(String format) Sets column structure according to Apache Log Format specification.
