Constructor Details

ObjectSingleValueSource

public ObjectSingleValueSource(Class<T> type)

Method Details

set

public final void set(T value)

Overrides:

set in class SingleValueColumnSource<T>

set

public final void set(long key,
 T value)

Specified by:

set in interface WritableSource<T>

setNull

public final void setNull(long key)

Specified by:

setNull in interface WritableSource<T>

setNull

public final void setNull(OrderedKeys keys)

Specified by:

setNull in interface WritableSource<T>

get

public final T 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 ElementSource<T>

Parameters:

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

Returns:

the value at the index, potentially null.

getPrev

public final T getPrev(long index)

Description copied from interface: ElementSource

Get the previous value at the index. Previous values are used during an LTM update cycle to process changes in data. During normal operation previous values will be identical to current values.

Specified by:

getPrev in interface ElementSource<T>

Parameters:

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

Returns:

the previous value at the index, or null.

copy

public final void copy(ColumnSource<T> sourceColumn,
 long sourceKey,
 long destKey)

Specified by:

copy in interface WritableSource<T>

fillFromChunk

public final void fillFromChunk(@NotNull
 WritableChunkSink.FillFromContext context,
 @NotNull
 Chunk<? extends Attributes.Values> src,
 @NotNull
 OrderedKeys orderedKeys)

Description copied from interface: WritableSource

Our default, inefficient, implementation. Inheritors who care should provide a better implementation.

Specified by:

fillFromChunk in interface WritableChunkSink<T>

Specified by:

fillFromChunk in interface WritableSource<T>

Parameters:

context - A context containing all mutable/state related data used in writing the Chunk.

src - The source of the data orderedKeys

orderedKeys - An OrderedKeys representing the keys to be written

fillFromChunkUnordered

public void fillFromChunkUnordered(@NotNull
 WritableChunkSink.FillFromContext context,
 @NotNull
 Chunk<? extends Attributes.Values> src,
 @NotNull
 LongChunk<Attributes.KeyIndices> keys)

Description copied from interface: WritableChunkSink

Fills the ChunkSink with data from the source, with data corresponding to the keys from the given key chunk.

Specified by:

fillFromChunkUnordered in interface WritableChunkSink<T>

Specified by:

fillFromChunkUnordered in interface WritableSource<T>

Parameters:

context - A context containing all mutable/state related data used in writing the Chunk.

src - The source of the data orderedKeys

keys - A LongChunk representing the keys to be written
