com.io7m.jtensors.bytebuffered.parameterized.PVectorByteBufferedM2D<T>

Type Parameters:

T - A phantom type parameter

All Implemented Interfaces:

ByteBufferedType, PVectorByteBuffered2DType<T>, PVector2DType<T>, PVectorReadable2DType<T>, PVectorWritable2DType<T>, Vector2DType, VectorReadable2DType, VectorWritable2DType

public final class PVectorByteBufferedM2D<T>
extends ByteBuffered
implements PVectorByteBuffered2DType<T>

A two-element vector type with double elements, packed into a ByteBuffer.

Values of this type cannot be accessed safely from multiple threads without explicit synchronization.

Method Detail

newVectorFromByteBuffer

public static <T> PVectorByteBuffered2DType<T> newVectorFromByteBuffer(ByteBuffer b,
                                                                       long byte_offset)

Return a new vector that is backed by whatever data is at byte offset byte_offset in the byte buffer .

No initialization of the data is performed.

Type Parameters:

T - A phantom type parameter

Parameters:

b - The byte buffer

byte_offset - A byte offset

Returns:

A new buffered vector

newVectorFromByteBufferAndBase

public static <T> PVectorByteBuffered2DType<T> newVectorFromByteBufferAndBase(ByteBuffer b,
                                                                              AtomicLong base,
                                                                              int offset)

Return a new vector that is backed by the given byte buffer b

The data for the instance will be taken from the data at the current value of base.get() + offset, each time a field is requested or set.

No initialization of the data is performed.

Type Parameters:

T - A phantom type parameter

Parameters:

b - The byte buffer

base - The base address

offset - A constant offset

Returns:

A new buffered vector
