Copy everything from one daf to another.

Mirrors Julia copy_all!(; destination, source, empty, types, overwrite, insist, relayout). Copies in order: scalars, axes, vectors, matrices. Tensors are not auto-expanded here — users can call copy_tensor() explicitly for per-main-axis-entry matrix groups.

Usage

copy_all(
  destination,
  source,
  empty = NULL,
  types = NULL,
  overwrite = FALSE,
  insist = TRUE,
  relayout = TRUE
)

Arguments

destination: A DafWriter.
source: A DafReader.
empty: Named list mapping flat keys to fill values: "axis|name" -> value for vectors, "rows|cols|name" -> value for matrices. Matrix keys accept either axis order.
types: Named list of type-coercion strings in the same flat-key form plus "name" (no pipes) for scalars.
overwrite: If TRUE, replace pre-existing destination entries.
insist: If TRUE (default) raise on pre-existing conflicts when overwrite = FALSE; if FALSE silently skip.
relayout: If TRUE (default), also write transposed layout for copied matrices.

Value

Invisibly, the destination.

Details

Axes already in the destination are not overwritten (regardless of the overwrite flag). A destination axis must be identical to or a subset of the source axis (else empty is required per-vector / per-matrix to fill missing entries). Unknown-to-source destination axes are left untouched.

Examples

src <- memory_daf(name = "src")
set_scalar(src, "organism", "human")
add_axis(src, "cell", c("c1", "c2"))
set_vector(src, "cell", "age", c(10L, 20L))
dest <- memory_daf(name = "dest")
copy_all(dest, src, relayout = FALSE)
