    • add

      public final void add​(int value)

    • slice

      public WritableIntChunk<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 IntChunk<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

    • copyFromTypedArray

      public final void copyFromTypedArray​(int[] 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 IntBuffer srcBuffer, int srcOffset, int destOffset, int length)

      Fill a sub-range of this WritableIntChunk with values from a IntBuffer.

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

      Parameters:
      srcBuffer - The source IntBuffer
      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

      public final void sort()
      Description copied from interface: WritableChunk
