public Data(WinstonDatabase w)

Constructor

Parameters:

w - WinstonDatabase

Method Detail

getTimeSpan

public double[] getTimeSpan(String code)

Get timespan for specific channel

Parameters:

code - channel code

Returns:

Array of start and end times

getTimeSpan

public double[] getTimeSpan(int sid)

Get timespan for specific channel

Parameters:

sid - channel id

Returns:

Array of start and end times

findGaps

public List<double[]> findGaps(String code,
                      double t1,
                      double t2)

Finds data gaps in a given channel between two times. Returns null on a Winston error. Returns a single item list with the given time span if the channel doesn't exist or if no data exist in the interval.

Parameters:

code -

t1 -

t2 -

Returns:

List of data gaps (each gap by a start and end time)

getWave

public gov.usgs.plot.data.Wave getWave(int sid,
                              double t1,
                              double t2,
                              int maxrows)
                                throws gov.usgs.volcanoes.core.util.UtilException

Return wave data for timespan t1..t2 for channel w/ id sid; cap result at maxrows size. Currently returns larger than asked for.

Parameters:

sid - id of channel

t1 - start time

t2 - end time

maxrows - cap on size of result

Returns:

wave

Throws:

gov.usgs.volcanoes.core.util.UtilException

getTraceBufBytes

public List<byte[]> getTraceBufBytes(String code,
                            double t1,
                            double t2,
                            int maxrows)
                              throws gov.usgs.volcanoes.core.util.UtilException

Modified 2006-08-14 to not check for consistent sample rates. That duty is passed to TraceBuf.traceBufsToWave(). This should fix the HVO bug that trig2disk can not get tracebufs with varying sample rates.

Parameters:

code -

t1 -

t2 -

maxrows -

Returns:

trace buf data

Throws:

gov.usgs.volcanoes.core.util.UtilException

getTraceBufs

public List<gov.usgs.earthworm.message.TraceBuf> getTraceBufs(String code,
                                                     double t1,
                                                     double t2,
                                                     int maxrows)
                                                       throws gov.usgs.volcanoes.core.util.UtilException

Throws:

getWave

public gov.usgs.plot.data.Wave getWave(String code,
                              double t1,

                              int maxrows)
                                throws gov.usgs.volcanoes.core.util.UtilException

Return wave data for timespan t1..t2 for channel w/ code; cap result at maxrows size. Currently returns larger than asked for.

Parameters:

code - channel

t1 - start time

t2 - end time

Returns:

wave

Throws:
