Constructor Details

WritableRedirectedColumnSource

protected WritableRedirectedColumnSource(@NotNull
 @NotNull RowRedirection rowRedirection,
 @NotNull
 @NotNull ColumnSource<T> innerSource,
 long maxInnerIndex)

Create a type-appropriate WritableRedirectedColumnSource for the supplied WritableRowRedirection and inner ColumnSource.

Parameters:

rowRedirection - The row redirection to use

innerSource - The column source to redirect

maxInnerIndex - The maximum row key available in innerSource

Method Details

maybeRedirect

public static <T> WritableColumnSource<T> maybeRedirect(@NotNull
 @NotNull RowRedirection rowRedirection,
 @NotNull
 @NotNull WritableColumnSource<T> innerSource,
 long maxInnerIndex)

Redirect the innerSource if it is not agnostic to redirection. Otherwise, return the innerSource.

Parameters:

rowRedirection - The row redirection to use

innerSource - The column source to redirect

maxInnerIndex - The maximum row key available in innerSource

setNull

public void setNull(long key)

Specified by:

setNull in interface WritableColumnSource<T>

set

ensureCapacity

public void ensureCapacity(long capacity,
 boolean nullFill)

Description copied from interface: WritableColumnSource

Ensure that this WritableColumnSource can accept row keys in range [0, capacity).

Specified by:

ensureCapacity in interface WritableColumnSource<T>

Parameters:

capacity - The new minimum capacity

nullFill - Whether data should be "null-filled". If true, get operations at row keys that have not been set will return the appropriate null value; otherwise such gets produce undefined results.

makeFillFromContext

public ChunkSink.FillFromContext makeFillFromContext(int chunkCapacity)

Description copied from interface: WritableColumnSource

Provide a default, empty ChunkSink.FillFromContext for use with our default WritableColumnSource.fillFromChunk(io.deephaven.engine.table.ChunkSink.FillFromContext, io.deephaven.chunk.Chunk<? extends io.deephaven.chunk.attributes.Values>, io.deephaven.engine.rowset.RowSequence).

Specified by:

makeFillFromContext in interface ChunkSink<T>

Specified by:

makeFillFromContext in interface WritableColumnSource<T>

fillFromChunk

public void fillFromChunk(@NotNull
 @NotNull ChunkSink.FillFromContext context,
 @NotNull
 @NotNull Chunk<? extends Values> src,
 @NotNull
 @NotNull RowSequence rowSequence)

Description copied from interface: WritableColumnSource

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

Specified by:

fillFromChunk in interface ChunkSink<T>

Specified by:

fillFromChunk in interface WritableColumnSource<T>

Parameters:

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

src - The source of the data rowSequence

rowSequence - An RowSequence representing the keys to be written

fillFromChunkUnordered

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

Description copied from interface: ChunkSink

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

Specified by:

fillFromChunkUnordered in interface ChunkSink<T>

Specified by:

fillFromChunkUnordered in interface WritableColumnSource<T>

Parameters:

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

src - The source of the data RowSequence

keys - A LongChunk representing the keys to be written

allowsReinterpret

public <ALTERNATE_DATA_TYPE> boolean allowsReinterpret(@NotNull
 @NotNull Class<ALTERNATE_DATA_TYPE> alternateDataType)

Description copied from interface: ColumnSource

Test if a reinterpret call will succeed.

Specified by:

allowsReinterpret in interface ColumnSource<T>

Overrides:

allowsReinterpret in class RedirectedColumnSource<T>

Parameters:

alternateDataType - The alternative type to consider

Returns:

If a reinterpret on this column source with the supplied alternateDataType will succeed.

doReinterpret

protected <ALTERNATE_DATA_TYPE>
ColumnSource<ALTERNATE_DATA_TYPE> doReinterpret(@NotNull
 @NotNull Class<ALTERNATE_DATA_TYPE> alternateDataType)

Description copied from class: AbstractColumnSource

Supply allowed reinterpret results. The default implementation handles the most common case to avoid code duplication.

Overrides:

doReinterpret in class RedirectedColumnSource<T>

Parameters:

alternateDataType - The alternate data type

Returns:

The resulting ColumnSource
