Method Details

makeWritableChunk

public static <ATTR extends Attributes.Any> WritableDoubleChunk<ATTR> makeWritableChunk(int size)

makeWritableChunkForPool

public static WritableDoubleChunk makeWritableChunkForPool(int size)

writableChunkWrap

public static <ATTR extends Attributes.Any> WritableDoubleChunk<ATTR> writableChunkWrap(double[] data)

writableChunkWrap

public static <ATTR extends Attributes.Any> WritableDoubleChunk<ATTR> writableChunkWrap(double[] data, int offset, int size)

set

public final void set(int index, double value)

add

public final void add(double value)

slice

public WritableDoubleChunk<ATTR> slice(int offset, int capacity)

Description copied from interface: Chunk

Make a new Chunk that represents either exactly the same view on the underlying data as this Chunk, or a subrange of that view. The view is defined as [0..size) (in the coordinate space of this Chunk).

Specified by:

slice in interface Chunk<ATTR extends Attributes.Any>

Specified by:

slice in interface WritableChunk<ATTR extends Attributes.Any>

Overrides:

slice in class DoubleChunk<ATTR extends Attributes.Any>

Parameters:

offset - Offset of the new Chunk, relative to this Chunk. 0 ≤ offset ≤ this.size

capacity - Capacity and initial size of the new Chunk. 0 ≤ capacity ≤ this.size - offset.

Returns:

The new Chunk. A new Chunk will always be returned, even if the Chunks represent the same view.

fillWithNullValue

public final void fillWithNullValue(int offset, int length)

Description copied from interface: WritableChunk

Fill a sub-range of this writable chunk with the appropriate Deephaven null value for the type.

Specified by:

fillWithNullValue in interface WritableChunk<ATTR extends Attributes.Any>

Parameters:

offset - Starting offset

length - Number of values to fill

fillWithBoxedValue

public final void fillWithBoxedValue(int offset, int size, Object value)

Description copied from interface: WritableChunk

Fill a sub-range of this writable chunk with the given value, unboxing it as appropriate.

Specified by:

fillWithBoxedValue in interface WritableChunk<ATTR extends Attributes.Any>

Parameters:

offset - Starting offset

size - Number of values to fill

fillWithValue

public final void fillWithValue(int offset, int length, double value)

appendTypedChunk

public final void appendTypedChunk(DoubleChunk<? extends ATTR> src, int srcOffset, int length)

copyFromChunk

public final void copyFromChunk(Chunk<? extends ATTR> src, int srcOffset, int destOffset, int length)

Specified by:

copyFromChunk in interface WritableChunk<ATTR extends Attributes.Any>

copyFromTypedChunk

public final void copyFromTypedChunk(DoubleChunk<? extends ATTR> src, int srcOffset, int destOffset, int length)

copyFromArray

public final void copyFromArray(Object srcArray, int srcOffset, int destOffset, int length)

Specified by:

copyFromArray in interface WritableChunk<ATTR extends Attributes.Any>

copyFromTypedArray

public final void copyFromTypedArray(double[] src, int srcOffset, int destOffset, int length)

copyFromBuffer

public final void copyFromBuffer(@NotNull Buffer srcBuffer, int srcOffset, int destOffset, int length)

Description copied from interface: WritableChunk

Fill a sub-range of this writable chunk with values from a Buffer. This is an optional method, as some chunk types do not have a corresponding buffer type.

Implementations are free to copy data as efficiently as they may, and will use absolute rather than positional access where possible. To facilitate this pattern, srcOffset is an absolute offset from position 0, rather than a relative offset from srcBuffer.position().

It is required that srcBuffer.limit() is at least srcOffset + length.

srcBuffer's position may be modified, but will always be restored to its initial value upon successful return.

Specified by:

copyFromBuffer in interface WritableChunk<ATTR extends Attributes.Any>

Parameters:

srcBuffer - The source buffer, which will be cast to the appropriate type for this chunk

srcOffset - The offset into srcBuffer (from position 0, not srcBuffer.position()) to start copying from

destOffset - The offset into this chunk to start copying to

length - The number of elements to copy

copyFromTypedBuffer

public final void copyFromTypedBuffer(@NotNull DoubleBuffer srcBuffer, int srcOffset, int destOffset, int length)

Fill a sub-range of this WritableDoubleChunk with values from a DoubleBuffer.

See copyFromBuffer(Buffer, int, int, int) for general documentation.

Parameters:

srcBuffer - The source DoubleBuffer

srcOffset - The absolute offset into srcBuffer to start copying from

destOffset - The offset into this chunk to start copying to

length - The number of elements to copy

getChunkFiller

public final ChunkFiller getChunkFiller()

Description copied from interface: WritableChunk

Our ChunkFiller "plugin".

Specified by:

getChunkFiller in interface WritableChunk<ATTR extends Attributes.Any>

sort

public final void sort()

Description copied from interface: WritableChunk

Sort this chunk in-place using Java's primitive defined ordering. Of note is that nulls or NaNs are not sorted according to Deephaven ordering rules.

Specified by:

sort in interface WritableChunk<ATTR extends Attributes.Any>

sort

public final void sort(int start, int length)

Description copied from interface: WritableChunk

Sort this chunk in-place using Java's primitive defined ordering. Of note is that nulls or NaNs are not sorted according to Deephaven ordering rules.

Specified by:

sort in interface WritableChunk<ATTR extends Attributes.Any>

close

public void close()

Specified by:

close in interface AutoCloseable

Specified by:
