Method Details

get

public long get(long index)

Description copied from interface: LongVector

Get the element of this LongVector at offset index. If index is not within range [0, size()), will return the null long.

Parameters:

index - An offset into this LongVector

Returns:

The element at the specified offset, or the null long

subVector

public LongVector subVector(long fromIndexInclusive,
 long toIndexExclusive)

Description copied from interface: Vector

Get a Vector that represents a slice of this Vector.

Parameters:

fromIndexInclusive - The first offset into this Vector to include in the result; if negative, the result will have a range of null values at offsets in [0, -fromIndexInclusive)

toIndexExclusive - The first offset into this Vector to not include in the result; if larger than size(), the result will have a range of null values at the corresponding offsets

Returns:

The sub-Vector specified by [fromIndexInclusive, toIndexExclusive)

subVectorByPositions

public LongVector subVectorByPositions(long[] positions)

Description copied from interface: Vector

Get a Vector that represents a set of offset positions in this Vector.

Parameters:

positions - The offsets to include; if not within [0, size()), the corresponding offset in the result will contain the appropriate null value

Returns:

The sub-Vector specified by positions

toArray

public long[] toArray()

Description copied from interface: Vector

Get an array representation of the elements of this Vector. Callers must not mutate the result, as implementations may choose to return their backing array in some cases.

Specified by:

toArray in interface LongVector

Specified by:

toArray in interface Vector<LongVector>

Overrides:

toArray in class LongVector.Indirect

Returns:

An array representation of the elements of this Vector that must not be mutated

toArray

public long[] toArray(boolean shouldBeNullIfOutOfBounds,
 int maxSize)

iterator

public CloseablePrimitiveIteratorOfLong iterator(long fromIndexInclusive,
 long toIndexExclusive)

Description copied from interface: LongVector

Returns an iterator over a slice of this vector, with equivalent semantics to subVector(fromIndexInclusive, toIndexExclusive).iterator().

Parameters:

fromIndexInclusive - The first position to include

toIndexExclusive - The first position after fromIndexInclusive to not include

Returns:

An iterator over the requested slice

size

public long size()

Description copied from interface: LongSizedDataStructure

The size of this data structure.

Returns:

The size
