AxisArrayConversion

AxisArrayConversion

AxisArrayConversion.jl allows converting between AxisArrays.jl like packages.

• AxisArrays.AxisArray
• AxisKeys.KeyedArray
• DimensionalData.DimArray
• AxisArrayConversion.SimpleAxisArray
• Base.NamedTuple

Supporting more arrays

Conversions between two array types is provided by using the path

MyArray -> NamedTuple -> OtherArray

This has multiple advantages:

• For N array types, only 2N methods must be implemented.
• Conversion can be implemented between packages that don't know about each other.

In order to support MyArray, the following must be implemented:

function AxisArrayConversion.namedtuple(arr::MyArray)
...return (axes=..., values=...)
endfunction AxisArrayConversion.from_namedtuple(::Type{MyArray}, nt::NamedTuple)
...= nt.axes
...= nt.values
returnMyArray(...)
end

And now any fancy conversion should work

using MyArrays, OtherArrays
using AxisArrayConversion: to
using Test
ma =MyArrays(...)
oa =to(OtherArray, ma)
@test oa isa OtherArrays.OtherArray
@test ma ==to(MyArray, oa)
