Method Details

getColumnKey

public K getColumnKey()

createAggregated

public static HistorianDataColumn<AggregatedQueryKey> createAggregated(QueryController controller,
 ColumnQueryDefinition definition,
 QualifiedPathAdapter pathAdapter,
 boolean nativeAggregate)

createRaw

public static HistorianDataColumn<RawQueryKey> createRaw(QueryController controller,
 ColumnQueryDefinition definition,
 QualifiedPathAdapter pathAdapter)

getBuilder

public HistorianDataColumn.ColumnBuilder getBuilder()

The column maintains a builder that can be updated until the point which the first data arrives. At that point, the builder will be used to generate the underlying column type.

buildColumn

public void buildColumn()

isBuilt

public boolean isBuilt()

getDelegate

public ValueBasedResultNode getDelegate()

Overrides:

getDelegate in class DelegatingResultNode

setErrored

public void setErrored(QualityCode code)

Description copied from interface: ValueBasedResultNode

Sets the column to an error state.

Specified by:

setErrored in interface ValueBasedResultNode

Parameters:

code - The quality code representing the error

processValue

public void processValue(QualifiedValue value)

Description copied from interface: ValueBasedResultNode

Processes a single value.

Specified by:

processValue in interface ValueBasedResultNode

Parameters:

value - The qualified value to process
