All Implemented Interfaces:

ChunkSource<Attributes.Values>, ChunkSource.WithPrev<Attributes.Values>, DefaultChunkSource<Attributes.Values>, DefaultChunkSource.WithPrev<Attributes.Values>, FillContextMaker, GetContextMaker, ColumnSource<DBDateTime>, ColumnSourceGetDefaults.ForObject<DBDateTime>, ElementSource<DBDateTime>, MutableColumnSource<DBDateTime>, MutableColumnSourceGetDefaults.ForObject<DBDateTime>, Releasable, TupleExporter<DBDateTime>, TupleSource<DBDateTime>, TestColumnSource<DBDateTime>, Serializable

public class ImmutableDateTimeTestSource
extends AbstractColumnSource<DBDateTime>
implements MutableColumnSourceGetDefaults.ForObject<DBDateTime>, TestColumnSource<DBDateTime>

DateTime column source that wraps and delegates the storage to an ImmutableLongTestSource<Long>. This also provides an interface so this column can be interpreted as a long column (through UnboxedDateTimeTestSource).

Constructor Details

ImmutableDateTimeTestSource

public ImmutableDateTimeTestSource()

Create a new ImmutableDateTimeTestSource with no initial data.

ImmutableDateTimeTestSource

public ImmutableDateTimeTestSource(ReadOnlyIndex index,
 Chunk<Attributes.Values> data)

Create a new DateTimeTreeMapSource with the given index and data.

Parameters:

index - The row indexes for the initial data

data - The initial data

Method Details

add

public void add(ReadOnlyIndex index,
 Chunk<Attributes.Values> data)

Description copied from interface: TestColumnSource

Add the chunk of data, parallel to index to this column source.

For TestColumnSources with primitive types, the chunk of data must either be of the appropriate primitive type or an ObjectChunk containing boxed values.

Specified by:

add in interface TestColumnSource<DBDateTime>

Parameters:

index - the index locations to add the data

data - the data to add

remove

public void remove(ReadOnlyIndex index)

Description copied from interface: TestColumnSource

Remove the given index from the column source.

Specified by:

remove in interface TestColumnSource<DBDateTime>

Parameters:

index - the keys to remove

shift

public void shift(long startKeyInclusive,
 long endKeyInclusive,
 long shiftDelta)

Description copied from interface: TestColumnSource

Move data within the column source.

Specified by:

shift in interface TestColumnSource<DBDateTime>

Parameters:

startKeyInclusive - the first key to shift

endKeyInclusive - the last key to shift

shiftDelta - how far to shift the data (either positive or negative)

get

public DBDateTime 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<DBDateTime>

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<DBDateTime>

Specified by:

isImmutable in interface MutableColumnSource<DBDateTime>

Returns:

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

getLong

public long getLong(long index)

Description copied from interface: ElementSource

Get the value at the index as a long.

Specified by:

getLong in interface ColumnSourceGetDefaults.ForObject<DBDateTime>

Specified by:

getLong in interface ElementSource<DBDateTime>

Parameters:

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

Returns:

the long at the index, null values are represented by QueryConstants.NULL_LONG

getPrev

public DBDateTime 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<DBDateTime>

Parameters:

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

Returns:

the previous value at the index, or null.

getPrevLong

public long getPrevLong(long index)

Description copied from interface: ElementSource

Get the previous value at the index as a long. See ElementSource.getPrev(long) for more details.

Specified by:

getPrevLong in interface ElementSource<DBDateTime>

Specified by:

getPrevLong in interface MutableColumnSourceGetDefaults.ForObject<DBDateTime>

Parameters:

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

Returns:

the previous long at the index, null values are represented by QueryConstants.NULL_LONG

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<DBDateTime>

Overrides:

allowsReinterpret in class AbstractColumnSource<DBDateTime>

Type Parameters:

ALTERNATE_DATA_TYPE - the dataType to inquire about

Parameters:

alternateDataType - The alternative type to consider

Returns:

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

doReinterpret

public <ALTERNATE_DATA_TYPE>
ColumnSource<ALTERNATE_DATA_TYPE> doReinterpret(@NotNull
 @NotNull Class<ALTERNATE_DATA_TYPE> alternateDataType)
                                         throws IllegalArgumentException

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 AbstractColumnSource<DBDateTime>

Type Parameters:

ALTERNATE_DATA_TYPE - the dataType to reinterpret to

Parameters:

alternateDataType - The alternate data type

Returns:

The resulting ColumnSource

Throws:

IllegalArgumentException
