Class ImmutableDoubleArraySource

java.lang.Object

com.illumon.iris.db.v2.sources.AbstractColumnSource<Double>

com.illumon.iris.db.v2.sources.immutable.ImmutableDoubleArraySource

All Implemented Interfaces:

ChunkSource<Attributes.Values>, ChunkSource.WithPrev<Attributes.Values>, DefaultChunkSource<Attributes.Values>, DefaultChunkSource.WithPrev<Attributes.Values>, FillContextMaker, GetContextMaker, ColumnSource<Double>, ColumnSourceGetDefaults.ForDouble, ElementSource<Double>, ImmutableColumnSource<Double>, ImmutableColumnSourceGetDefaults.ForDouble, Releasable, TupleExporter<Double>, TupleSource<Double>, Serializable

public class ImmutableDoubleArraySource
extends AbstractColumnSource<Double>
implements ImmutableColumnSourceGetDefaults.ForDouble

Simple array source for Immutable Double.

The ImmutableC-harArraySource is replicated to all other types with com.illumon.iris.db.v2.sources.Replicate. (C-har is deliberately spelled that way in order to prevent Replicate from altering this very comment).

Constructor Details

ImmutableDoubleArraySource

public ImmutableDoubleArraySource(double[] source)

Method Details

getDouble

public double getDouble(long index)

Description copied from interface: ElementSource

Get the value at the index as a double.

Specified by:

getDouble in interface ElementSource<Double>

Parameters:

index - the location in index space to get the value from.

Returns:

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

get

public Double get(long index)

Description copied from interface: ElementSource

Get the value from the source. This may return boxed values for basic types.

Specified by:

get in interface ColumnSourceGetDefaults.ForDouble

Specified by:

get in interface ElementSource<Double>

Parameters:

index - the location in index space to get the value from.

Returns:

the value at the index, potentially null.

isImmutable

public boolean isImmutable()

Description copied from interface: ColumnSource

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

Specified by:

isImmutable in interface ColumnSource<Double>

Specified by:

isImmutable in interface ImmutableColumnSource<Double>

Returns:

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