SelectAndViewAnalyzer

public SelectAndViewAnalyzer(int layerIndex)

Method Details

create

public static SelectAndViewAnalyzer create(SelectAndViewAnalyzer.Mode mode, Map<String,ColumnSource> columnSources, Index index, ModifiedColumnSet parentMcs, boolean publishTheseSources, SelectColumn... selectColumns)

setAllNewColumns

public void setAllNewColumns(BitSet bitset)

Set the bits in bitset that represent all of the new columns, this is used to identify when the select or update operaiton is complete

Parameters:

bitset - the bitset to manipulate.

getAllColumnSources

public final Map<String,ColumnSource> getAllColumnSources()

getNewColumnSources

public final Map<String,ColumnSource> getNewColumnSources()

getPublishedColumnSources

public final Map<String,ColumnSource> getPublishedColumnSources()

applyUpdate

public abstract void applyUpdate(ShiftAwareListener.Update upstream, ReadOnlyIndex toClear, SelectAndViewAnalyzer.UpdateHelper helper, SelectAndViewAnalyzer.JobScheduler jobScheduler, SelectAndViewAnalyzer.SelectLayerCompletionHandler onCompletion)

Apply this update to this SelectAndViewAnalyzer.

Parameters:

upstream - the upstream update

toClear - rows that used to exist and no longer exist

helper - convenience class that memoizes reusable calculations for this update

onCompletion - called when an inner column is complete, the outer layer should pass the completion on to other layers and if it all of it's dependencies have been satisfied schedule execution of that column update

calcEffects

public final Map<String,String[]> calcEffects()

Our job here is to calculate the effects: a map from incoming column to a list of columns that it effects. We do this in two stages. In the first stage we create a map from column to (set of dependent columns). In the second stage we reverse that map.

getInner

public abstract SelectAndViewAnalyzer getInner()

updateColumnDefinitionsFromTopLayer

public abstract void updateColumnDefinitionsFromTopLayer(Map<String,com.illumon.dataobjects.ColumnDefinition> columnDefinitions)

startTrackingPrev

public abstract void startTrackingPrev()

futureCompletionHandler

public SelectAndViewAnalyzer.SelectLayerCompletionHandler futureCompletionHandler(CompletableFuture<Void> waitForResult)

Create a completion handler that signals a future when the update is completed.

Parameters:

waitForResult - a void future indicating success or failure

Returns:

a completion handler that will signal the future

toString

public String toString()

Overrides:

toString in class Object
