Serialization

save(io::IO, obj::Any)
save(filename::String, obj::Any)

Save an object T to the given io stream respectively to the file filename.

See load.

Examples

julia> save("/tmp/fourtitwo.json", 42);

julia> load("/tmp/fourtitwo.json")
42

load(io::IO; parent::Any = nothing, type::Any = nothing)
load(filename::String; parent::Any = nothing, type::Any = nothing)

Load the object stored in the given io stream respectively in the file filename.

If parent is specified, then the root object of the loaded data either will have this as its parent, or it is a container such as Vector and Tuple, then the parent of the entries will be set to parent.

If a type T is given then attempt to load the root object of the data being loaded with this type; if this fails, an error is thrown.

See save.

Examples

julia> save("/tmp/fourtitwo.json", 42);

julia> load("/tmp/fourtitwo.json")
42

julia> load("/tmp/fourtitwo.json"; type=Int64)
42

julia> R, x = QQ["x"]
(Univariate polynomial ring in x over QQ, x)

julia> p = x^2 - x + 1
x^2 - x + 1

julia> save("/tmp/p.json", p)

julia> p_loaded = load("/tmp/p.json", parent=R)
x^2 - x + 1

julia> parent(p_loaded) === R
true

julia> save("/tmp/p_v.json", [p, p])

julia> loaded_p_v = load("/tmp/p_v.json", parent=R)
2-element Vector{QQPolyRingElem}:
 x^2 - x + 1
 x^2 - x + 1

julia> parent(loaded_p_v[1]) === parent(loaded_p_v[2]) === R
true

is_basic_serialization_type(::Type)

During the serialization of types of the form Vector{T}, entries of type T will either be serialized as strings if is_basic_serialization_type returns true, or serialized as a dict provided the serialization for such a T exists. If Vector{T} is serialized with is_basic_serialization_type(T) = true then the entry_type keyword is used to store the type T as a property of the vector.

Examples

julia> is_basic_serialization_type(ZZRingElem)
true
