All Superinterfaces:

AutoCloseable

All Known Implementing Classes:

public interface LogParser
extends AutoCloseable

LogParser iterates over a stream of logs, uses SingleLineParser to parse each line, and adds extracted ResourceSkylines to the SkylineStore.

Method Detail

init

void init(org.apache.hadoop.conf.Configuration config,
        HistorySkylineStore skylineStore)
          throws ResourceEstimatorException

Initializing the LogParser, including loading solver parameters from configuration file.

Parameters:

config - Configuration for the LogParser.

skylineStore - the HistorySkylineStore which stores recurring pipeline's ResourceSkylines.

Throws:

ResourceEstimatorException - if initialization of a SingleLineParser fails.

parseStream

void parseStream(InputStream logs)
                 throws SkylineStoreException,
                        IOException

Parses each line in the log stream, and adds extracted ResourceSkylines to the SkylineStore.

Parameters:

logs - the stream of input logs.

Throws:

SkylineStoreException - if it fails to addHistory extracted ResourceSkylines to the SkylineStore.

IOException - if it fails to read from the InputStream.
