All Implemented Interfaces:

ChunkSource<Values>, ChunkSource.WithPrev<Values>, ColumnSource<Double>, ElementSource<Double>, FillContextMaker, GetContextMaker, ColumnSourceGetDefaults.ForObject<Double>, DefaultChunkSource<Values>, DefaultChunkSource.WithPrev<Values>, MutableColumnSource<Double>, MutableColumnSourceGetDefaults.ForObject<Double>, Releasable, TupleExporter<Double>, TupleSource<Double>

public class UngroupedBoxedDoubleArrayColumnSource
extends UngroupedColumnSource<Double>
implements MutableColumnSourceGetDefaults.ForObject<Double>

An Ungrouped Column sourced for the Boxed Type Double.

The UngroupedBoxedC-harArrayColumnSource is replicated to all other types with io.deephaven.engine.table.impl.sources.Replicate. (C-har is deliberately spelled that way in order to prevent Replicate from altering this very comment).

Constructor Details

UngroupedBoxedDoubleArrayColumnSource

public UngroupedBoxedDoubleArrayColumnSource(ColumnSource<Double[]> innerSource)

Method Details

getComponentType

public Class<?> getComponentType()

Specified by:

getComponentType in interface ColumnSource<Double>

Overrides:

getComponentType in class AbstractColumnSource<Double>

get

public Double get(long rowKey)

Description copied from interface: ElementSource

Get the value from the source. This may return boxed values for basic types. RowKeys that are not present are undefined.

Specified by:

get in interface ElementSource<Double>

Parameters:

rowKey - the location in key space to get the value from.

Returns:

the value at the rowKey, potentially null.

getDouble

public double getDouble(long rowKey)

Description copied from interface: ElementSource

Get the value at the rowKey as a double. RowKeys that are not present are undefined.

Specified by:

getDouble in interface ColumnSourceGetDefaults.ForObject<Double>

Specified by:

getDouble in interface ElementSource<Double>

Parameters:

rowKey - the location in key space to get the value from.

Returns:

the double at the rowKey, null values are represented by QueryConstants.NULL_DOUBLE

getPrev

public Double getPrev(long rowKey)

Description copied from interface: ElementSource

Get the previous value at the rowKey. Previous values are used during an UG update cycle to process changes in data. During normal operation previous values will be identical to current values. RowKeys that were not present are undefined.

Specified by:

getPrev in interface ElementSource<Double>

Parameters:

rowKey - the location in key space to get the value from.

Returns:

the previous value at the rowKey, potentially null.

getPrevDouble

public double getPrevDouble(long rowKey)

Description copied from interface: ElementSource

Get the previous value at the rowKey as a double. See ElementSource.getPrev(long) for more details. RowKeys that were not present are undefined.

Specified by:

getPrevDouble in interface ElementSource<Double>

Specified by:

getPrevDouble in interface MutableColumnSourceGetDefaults.ForObject<Double>

Parameters:

rowKey - the location in key space to get the previous value from.

Returns:

the previous double at the rowKey, null values are represented by QueryConstants.NULL_DOUBLE

isImmutable

public boolean isImmutable()

Description copied from interface: ColumnSource

Determine if this column source is immutable, meaning that the values at a given row key never change.

Specified by:

isImmutable in interface ColumnSource<Double>

Specified by:

isImmutable in interface MutableColumnSource<Double>

Returns:

true if the values at a given row key of the column source never change, false otherwise
