Constructor Details

BooleanChunk

protected BooleanChunk(boolean[] data,

Method Details

getEmptyChunk

public static <ATTR extends Any> BooleanChunk<ATTR> getEmptyChunk()

makeArray

public static boolean[] makeArray(int capacity)

chunkWrap

public static <ATTR extends Any> BooleanChunk<ATTR> chunkWrap(boolean[] data)

chunkWrap

public static <ATTR extends Any> BooleanChunk<ATTR> chunkWrap(boolean[] data,
 int offset,
 int capacity)

getChunkType

public final ChunkType getChunkType()

Returns:

The underlying chunk type

get

public final boolean get(int index)

slice

public BooleanChunk<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).

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.

copyToChunk

public final void copyToChunk(int srcOffset,
 WritableChunk<? super ATTR> dest,
 int destOffset,
 int length)

Description copied from interface: Chunk

Copy a subrange of this Chunk to the subrange of the 'dest' writable chunk.

Parameters:

srcOffset - Starting position in 'this' (the source)

dest - Destination writable chunk.

destOffset - Starting offset in the destination.

length - Number of values to copy

copyToArray

public final void copyToArray(int srcOffset,
 Object dest,
 int destOffset,
 int length)

Description copied from interface: Chunk

Copy a subrange of this Chunk to the subrange of the 'dest' array.

Parameters:

srcOffset - Starting position in 'this' (the source)

dest - Destination array.

destOffset - Starting offset in the destination.

length - Number of values to copy

copyToTypedArray

public final void copyToTypedArray(int srcOffset,
 boolean[] destData,
 int destOffset,
 int length)

isAlias

public final boolean isAlias(Object array)

Returns:

true iff this and array are aliases, that is they refer to the same underlying data

isAlias

public final boolean isAlias(Chunk<?> chunk)

Returns:

true iff this and chunk are aliases, that is they refer to the same underlying data

walk

public final <V extends Chunk.Visitor<ATTR>> V walk(V visitor)

downcast

public static <ATTR extends Any,
ATTR_DERIV extends ATTR>
BooleanChunk<ATTR_DERIV> downcast(BooleanChunk<ATTR> self)
