org.openimaj.ml.timeseries.TimeSeries<Map<String,ALLINPUT>,Map<String,SINGLEINPUT>,TIMESERIES>

org.openimaj.ml.timeseries.collection.TimeSeriesCollection<ALLINPUT,SINGLEINPUT,TIMESERIES,INTERNALSERIES>

Type Parameters:

ALLINPUT - The collection input type

SINGLEINPUT - The type of a single data type

TIMESERIES - the type of time series returned

INTERNALSERIES - the type of time series held

All Implemented Interfaces:

Iterable<IndependentPair<Long,Map<String,SINGLEINPUT>>>

Direct Known Subclasses:

DoubleTimeSeriesCollection, SynchronisedTimeSeriesCollection, WordDFIDFTimeSeriesCollection

public abstract class TimeSeriesCollection<ALLINPUT,SINGLEINPUT,TIMESERIES extends TimeSeriesCollection<ALLINPUT,SINGLEINPUT,TIMESERIES,INTERNALSERIES>,INTERNALSERIES extends TimeSeries<ALLINPUT,SINGLEINPUT,INTERNALSERIES>>
extends TimeSeries<Map<String,ALLINPUT>,Map<String,SINGLEINPUT>,TIMESERIES>

A collection of time series which share exactly the same time steps. Given that this is true, SynchronisedTimeSeriesProcessor instances can perform interesting analysis

Method Detail

addTimeSeries

public void addTimeSeries(String name,
                          INTERNALSERIES series)
                   throws IncompatibleTimeSeriesException

Parameters:

name -

series -

Throws:

IncompatibleTimeSeriesException

series

public INTERNALSERIES series(String name)

Parameters:

name - the name of the series

Returns:

the series held by the name

allseries

public Collection<INTERNALSERIES> allseries()

Returns:

all the time series held

get

public TIMESERIES get(long time,
                      int nbefore,
                      int nafter)

Description copied from class: TimeSeries

returns the DATA at a specific point in time and those before and after to the number requested. This method may not return data for the specific requested time if it does not exists. If the time series is completely empty this function may return at an empty array however if at least 1 data point exists and either nbefore and nafter are bigger than 1 then at least 1 datapoint will be returned.

Data should be returned in order

Specified by:

get in class TimeSeries<Map<String,ALLINPUT>,Map<String,SINGLEINPUT>,TIMESERIES extends TimeSeriesCollection<ALLINPUT,SINGLEINPUT,TIMESERIES,INTERNALSERIES>>

Returns:

all data found with these parameters

getData

public Map<String,ALLINPUT> getData()

Specified by:

getData in class TimeSeries<Map<String,ALLINPUT>,Map<String,SINGLEINPUT>,TIMESERIES extends TimeSeriesCollection<ALLINPUT,SINGLEINPUT,TIMESERIES,INTERNALSERIES>>

all data

get

public TIMESERIES get(long start,
                      long end)

Description copied from class: TimeSeries

returns the RETURNTYPE between the specified time periods. This method may not return data for the specific requested time if it does not exists. Similarly this method may return an empty array if no time data is available within the window specified.

Data should be returned in order

Specified by:

get in class TimeSeries<Map<String,ALLINPUT>,Map<String,SINGLEINPUT>,TIMESERIES extends TimeSeriesCollection<ALLINPUT,SINGLEINPUT,TIMESERIES,INTERNALSERIES>>

                      TIMESERIES output)

Description copied from class: TimeSeries

Same as TimeSeries.get(long, int, int) but instead of createing the output DATA instance, an existing data instance is handed which is filled. For convenience this output is also returned

Data should be returned in order

Specified by:

get in class TimeSeries<Map<String,ALLINPUT>,Map<String,SINGLEINPUT>,TIMESERIES extends TimeSeriesCollection<ALLINPUT,SINGLEINPUT,TIMESERIES,INTERNALSERIES>>
