MemorySegmentTensorData

Off-heap, 64-byte-aligned tensor data backed by a MemorySegment.

This avoids GC pressure and enables direct use with the Vector API's FloatVector.fromMemorySegment for SIMD-friendly access patterns.

Two constructors:

Constructors

constructor(shape: Shape, arena: Arena, alignment: Long = 64)

Allocates a new off-heap segment from arena with the given alignment.

constructor(shape: Shape, segment: MemorySegment, byteOffset: Long = 0)

Wraps an existing segment region starting at byteOffset (zero-copy slice).

Byte length of the data region.

open override val segment: MemorySegment

The underlying off-heap memory segment.

Byte offset into segment where this tensor's data starts.

open override val shape: Shape

The shape descriptor that defines the dimensionality and size of this tensor data.

Total number of floats in this tensor.

fun copyFromFloatArray(src: FloatArray, srcOffset: Int = 0, length: Int = volume)

Bulk-copy a FloatArray into this tensor's segment.

Copies all tensor data to a FloatArray.

open operator override fun get(vararg indices: Int): Float

Retrieves an element at the specified multidimensional indices.

open operator override fun set(vararg indices: Int, value: Float)

Setter

Returns a zero-copy view into this tensor's segment. The returned view shares the same underlying memory.
