MultiVectorEmbedding class

A ColBERT multi-vector embedding: one row per attention-live token.

data is a flat, row-major buffer of length num_tokens * dim — row i (the embedding for token i) occupies data[i*dim .. (i+1)*dim]. Flat storage keeps the type FFI-friendly across binding boundaries; use `MultiVectorEmbedding::rows` internally to iterate per-token slices.

Properties

data → Float64List

Flat row-major buffer, length num_tokens * dim.

final

dim → int

Dimensionality of each per-token vector.

final

hashCode → int

no setter, override

numTokens → int

Number of attention-live token rows (padding rows are dropped, not zeroed — see `engine::normalize_tokens`).

final

runtimeType → Type
