Method Details

makeWritableChunk

public static <ATTR extends Any>
WritableBooleanChunk<ATTR> makeWritableChunk(int size)

Get a WritableBooleanChunk with ChunkBase.size() of size for use by the caller until it is closed.

Parameters:

size - The ChunkBase.size() and minimum capacity of the returned chunk

Returns:

The chunk

writableChunkWrap

public static <ATTR extends Any>
WritableBooleanChunk<ATTR> writableChunkWrap(boolean[] data)

writableChunkWrap

public static <ATTR extends Any>
WritableBooleanChunk<ATTR> writableChunkWrap(boolean[] data,
 int offset,
 int size)

set

public final void set(int index,
 boolean value)

add

public final void add(boolean value)

slice

public WritableBooleanChunk<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 Any>

Specified by:

slice in interface WritableChunk<ATTR extends Any>

Overrides:

slice in class BooleanChunk<ATTR extends 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.

array

public final boolean[] array()

Get the data array backing this WritableBooleanChunk. The first element of this chunk corresponds to array()[arrayOffset()].

This WritableBooleanChunk must never be closed while the array may be in use externally, because it must not be returned to any pool for re-use until that re-use is guaranteed to be exclusive.

Returns:

The backing data array

arrayOffset

public final int arrayOffset()

Get this WritableBooleanChunk's offset into the backing data array. The first element of this chunk corresponds to array()[arrayOffset()].

Returns:

The offset into the backing data array

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 Any>

Parameters:

offset - Starting offset

size - Number of values to fill

fillWithValue

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

appendTypedChunk

public final void appendTypedChunk(BooleanChunk<? 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 Any>

copyFromTypedChunk

public final void copyFromTypedChunk(BooleanChunk<? 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 Any>

copyFromTypedArray

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

sort

public final void sort()

Description copied from interface: WritableChunk

Sort this chunk in place using Deephaven-defined ordering where null (or QueryConstants.NULL_XXXX for value types) is less than all other values and Double.NaN / Float.NaN are greater than all other values.

Specified by:

sort in interface WritableChunk<ATTR extends Any>

close

public void close()

Specified by:

close in interface AutoCloseable

Specified by:

close in interface SafeCloseable

upcast

public static <ATTR extends Any,
ATTR_DERIV extends ATTR>
WritableBooleanChunk<ATTR> upcast(WritableBooleanChunk<ATTR_DERIV> self)
