Method Details

zero
Returns a vector of the given species where all lane elements are set to zero, the default primitive value. Parameters:
species
 species of the desired zero vector Returns:
 a zero vector

broadcast
Returns a vector of the same species as this one where all lane elements are set to the primitive valuee
. The contents of the current vector are discarded; only the species is relevant to this operation.This method returns the value of this expression:
ByteVector.broadcast(this.species(), e)
. API Note:
 Unlike the similar method named
broadcast()
in the supertypeVector
, this method does not need to validate its argument, and cannot throwIllegalArgumentException
. This method is therefore preferable to the supertype method.  Parameters:
e
 the value to broadcast Returns:
 a vector where all lane elements are set to
the primitive value
e
 See Also:

broadcast
Returns a vector of the given species where all lane elements are set to the primitive valuee
. Parameters:
species
 species of the desired vectore
 the value to broadcast Returns:
 a vector where all lane elements are set to
the primitive value
e
 See Also:

broadcast
Returns a vector of the same species as this one where all lane elements are set to the primitive valuee
. The contents of the current vector are discarded; only the species is relevant to this operation.This method returns the value of this expression:
EVector.broadcast(this.species(), (ETYPE)e)
, whereEVector
is the vector class specific to this vector's element typeETYPE
.The
long
valuee
must be accurately representable by theETYPE
of this vector's species, so thate==(long)(ETYPE)e
. If this rule is violated the problem is not detected statically, but anIllegalArgumentException
is thrown at runtime. Thus, this method somewhat weakens the static type checking of immediate constants and other scalars, but it makes up for this by improving the expressiveness of the generic API. Note that ane
value in the range[128..127]
is always acceptable, since everyETYPE
will accept everybyte
value. Specified by:
broadcast
in classVector<Byte>
 API Note:
 When working with vector subtypes like
ByteVector
, the more strongly typed method is typically selected. It can be explicitly selected using a cast:v.broadcast((byte)e)
. The two expressions will produce numerically identical results.  Parameters:
e
 the value to broadcast Returns:
 a vector where all lane elements are set to
the primitive value
e
 See Also:

broadcast
Returns a vector of the given species where all lane elements are set to the primitive valuee

 the value to broadcast Returns:
 a vector where all lane elements are set to
the primitive value

value cannot be represented by the vector'sETYPE

reduceLanes
Returns a value accumulated from all the lanes of this vector. This is an associative crosslane reduction operation which applies the specified operation to all the lane elements.A few reduction operations do not support arbitrary reordering of their operands, yet are included here because of their usefulness.

In the case of
FIRST_NONZERO
, the reduction returns the value from the lowestnumbered nonzero lane.  All other reduction operations are fully commutative and associative. The implementation can choose any order of processing, yet it will always produce the same result.
 Parameters:
op
 the operation used to combine lane values Returns:
 the accumulated result
 Throws:
UnsupportedOperationException
 if this vector does not support the requested operation See Also:

In the case of

reduceLanes
Returns a value accumulated from selected lanes of this vector, controlled by a mask. This is an associative crosslane reduction operation which applies the specified operation to the selected lane elements.If no elements are selected, an operationspecific identity value is returned.

If the operation is

convert
Convert this vector to a vector of the same shape and a new element type, converting lane values from the currentETYPE
to a new lane type (calledFTYPE
here) according to the indicated conversion. This is a lanewise shapeinvariant operation which copiesETYPE
values from the input vector to correspondingFTYPE
values in the result. Depending on the selected conversion, this operation may either expand or contract its logical result, in which case a nonzeropart
number can further control the selection and steering of the logical result into the physical output vector.Each specific conversion is described by a conversion constant in the class
VectorOperators
. Each conversion operator has a specified domain type and range type. The domain type must exactly match the lane type of the input vector, while the range type determines the lane type of the output vectors.A conversion operator may be classified as (respectively) inplace, expanding, or contracting, depending on whether the bitsize of its domain type is (respectively) equal, less than, or greater than the bitsize of its range type.
Independently, conversion operations can also be classified as reinterpreting or valuetransforming, depending on whether the conversion copies representation bits unchanged, or changes the representation bits in order to retain (part or all of) the logical value of the input value.
If a reinterpreting conversion contracts, it will truncate the upper bits of the input. If it expands, it will pad upper bits of the output with zero bits, when there are no corresponding input bits.
An expanding conversion such as
S2I
(short
value toint
) takes a scalar value and represents it in a larger format (always with some information redundancy). A contracting conversion such asD2F
(double
value tofloat
) takes a scalar value and represents it in a smaller format (always with some information loss). Some inplace conversions may also include information loss, such asL2D
(long
value todouble
) orF2I
(float
value toint
). Reinterpreting inplace conversions are not lossy, unless the bitwise value is somehow not legal in the output type. Converting the bitpattern of aNaN
may discard bits from theNaN
's significand.This classification is important, because, unless otherwise documented, conversion operations never change vector shape, regardless of how they may change lane sizes. Therefore an expanding conversion cannot store all of its results in its output vector, because the output vector has fewer lanes of larger size, in order to have the same overall bitsize as its input. Likewise, a contracting conversion must store its relatively small results into a subset of the lanes of the output vector, defaulting the unused lanes to zero.
As an example, a conversion from
byte
tolong
(M=8
) will discard 87.5% of the input values in order to convert the remaining 12.5% into the roomylong
lanes of the output vector. The inverse conversion will convert back all of the large results, but will waste 87.5% of the lanes in the output vector. Inplace conversions (M=1
) deliver all of their results in one output vector, without wasting lanes.To manage the details of these expansions and contractions, a nonzero
part
parameter selects partial results from expansions, or steers the results of contractions into corresponding locations, as follows: expanding by
M
:part
must be in the range[0..M1]
, and selects the block ofVLENGTH/M
input lanes starting at the origin lane atpart*VLENGTH/M
.The
VLENGTH/M
output lanes represent a partial slice of the whole logical result of the conversion, filling the entire physical output vector.  contracting by
M
:part
must be in the range[M+1..0]
, and steers allVLENGTH
input lanes into the output located at the origin lanepart*VLENGTH
. There is a total ofVLENGTH*M
output lanes, and those not holding converted input values are filled with zeroes.A group of such output vectors, with logical result parts steered to disjoint blocks, can be reassembled using the bitwise or or (for floating point) the
FIRST_NONZERO
operator.  inplace (
M=1
):part
must be zero. Both vectors have the sameVLENGTH
. The result is always positioned at the origin lane of zero.
This method is a restricted version of the more general but less frequently used shapechanging method
convertShape()
. The result of this method is the same as the expressionthis.convertShape(conv, rsp, this.broadcast(part))

convertShape
public abstract <F> Vector<F> convertShape(VectorOperators.Conversion<Byte, F> conv, VectorSpecies<F> rsp, int part) Converts this vector to a vector of the given species, shape and element type, converting lane values from the currentETYPE
to a new lane type (calledFTYPE
here) according to the indicated conversion. This is a lanewise operation which copiesETYPE
values from the input vector to correspondingFTYPE
values in the result.If the old and new species have the same shape, the behavior is exactly the same as the simpler, shapeinvariant method
convert()
. In such cases, the simpler methodconvert()
should be used, to make code easier to reason about. Otherwise, this is a shapechanging operation, and may have special implementation costs.As a combined effect of shape changes and lane size changes, the input and output species may have different lane counts, causing expansion or contraction. In this case a nonzero
part
parameter selects partial results from an expanded logical result, or steers the results of a contracted logical result into a physical output vector of the required output species.The following pseudocode illustrates the behavior of this method for inplace, expanding, and contracting conversions. (This pseudocode also applies to the shapeinvariant method, but with shape restrictions on the output species.) Note that only one of the three code paths is relevant to any particular combination of conversion operator and shapes.
