PROP_FILLPROPERTIES

PROP_REDUCEDATASETSTRING

PROP_URINEEDSRESOLUTION

true if the URI has been changed, and must be resolved into a DataSource.

PROP_DATASETNEEDSLOADING

true is the DataSource has been changed, and we need to reload.

cancel

cancel( ) → void

cancel the loading process.

Returns:

void (returns nothing)

getAppliedFiltersString

getAppliedFiltersString( ) → String

return documentation of any processes applied to the data within the DataSourceFilter. This will be an empty string when no processes were applied. See getFilters which specified which should be applied.

Returns:

reduceDataSetString the string, which may be empty but will not be null.

getDataSource

getDataSource( ) → org.autoplot.datasource.DataSource

return the controller's current datasource. This was synchronized, but this would mean that external clients could not query what the current source was. Since this is only reading the variable, this seems harmless. Note, findbugs prompted the code change, not an observed bug. TODO: there is probably a better way to do this, synchronizing properly on several objects.

Returns:

the controller's current datasource.

resetDataSource

resetDataSource( boolean valueWasAdjusting, org.autoplot.datasource.DataSource dataSource ) → void

This might be considered the heart of the DataSourceController. This is where TimeSeriesBrowse is set up as well as Caching. This might also be a good spot to make sure we are not on the event thread, and this is being studied.

Parameters

valueWasAdjusting - true if the app was loading a vap, or locked because of changes.
dataSource - a DataSource

Returns:

void (returns nothing)
