Constructor Detail

HistogramQuery

public HistogramQuery(java.lang.String datasource,
                      java.lang.String tableName,
                      java.lang.String timeCol)

Method Detail

getWholeQuery

protected AbstractSQLQuery.QueryInfo getWholeQuery()

Description copied from class: AbstractSQLQuery

Construct the query and any parameters

Specified by:

getWholeQuery in class AbstractSQLQuery

registerQuery

protected java.lang.Object registerQuery(int pollTime,
                                         boolean runOnce)

Description copied from class: AbstractChartQuery

Register this query with the QueryManager. Called by AbstractchartQuery during AbstractChartQuery.startup(PMIEasyChart)

Overrides:

registerQuery in class AbstractSQLQuery

Returns:

The key object that the query manager gave back.

setDates

protected void setDates(PMIEasyChart chart)

Description copied from class: AbstractSQLQuery

Called in order to set the AbstractSQLQuery.startDate and AbstractSQLQuery.endDate fields with proper late-binding IValue implementations.

Specified by:

setDates in class AbstractSQLQuery

startup

public void startup(PMIEasyChart chart)

Description copied from interface: IPenDatasource

Start this datasouce up. This should certainly mean that the data gets generated at least once, and possibly more based upon the chart's polling settings. May be called again after shutdown().

Specified by:

startup in interface IPenDatasource

Overrides:

startup in class AbstractChartQuery

setData

protected void setData(Dataset data)

Overrides:

setData in class AbstractChartQuery

getHistogram

public IHistogram getHistogram()

Specified by:

getHistogram in interface IHistogramDatasource

isDataIn

public boolean isDataIn()

addPen

public void addPen(PenData penData)

Description copied from interface: IPenDatasource

Adds a pen to this datasource. All pens will be added before startup() is called for the first time.

Specified by:

addPen in interface IPenDatasource

initRefs

public void initRefs(java.util.Map<java.lang.String,PenData> allPens)

Description copied from interface: IPenDatasource

Gives the datasource a chance to install references to other pens

Specified by:

initRefs in interface IPenDatasource

getNumDatapoints

public int getNumDatapoints()

Description copied from interface: IPenDatasource

Return the number of datapoints currently loaded in this source

Specified by:

getNumDatapoints in interface IPenDatasource

getDataset

public Dataset getDataset()

Description copied from interface: IPenDatasource

The underlying dataset that drives this datasource

Specified by:

getDataset in interface IPenDatasource

isZoomTracking

public boolean isZoomTracking()

Description copied from interface: IPenDatasource

True if this datasource should be restarted when the zoom level changes.

Specified by:

isZoomTracking in interface IPenDatasource
