@spec delete(t(), String.t()) :: {:ok, t()} | {:error, String.t()}

Deletes a value at the given JSON Pointer path.

Examples

iex> model = A2UI.DataModel.new(%{"a" => 1, "b" => 2})
iex> {:ok, model} = A2UI.DataModel.delete(model, "/a")
iex> model.data
%{"b" => 2}

@spec get(t(), String.t()) :: {:ok, any()} | :error

Gets a value at the given JSON Pointer path.

Returns {:ok, value} if found, :error if the path doesn't exist.

Examples

iex> model = A2UI.DataModel.new(%{"user" => %{"name" => "Alice"}})
iex> A2UI.DataModel.get(model, "/user/name")
{:ok, "Alice"}

iex> model = A2UI.DataModel.new(%{"a" => 1})
iex> A2UI.DataModel.get(model, "/")
{:ok, %{"a" => 1}}

@spec new() :: t()

Creates a new empty data model.

@spec new(map()) :: t()

Creates a data model with initial data.

@spec set(t(), String.t(), any()) :: {:ok, t()} | {:error, String.t()}

Sets a value at the given JSON Pointer path.

Auto-vivifies intermediate maps as needed.

Examples

iex> model = A2UI.DataModel.new()
iex> {:ok, model} = A2UI.DataModel.set(model, "/user/name", "Alice")
iex> A2UI.DataModel.get(model, "/user/name")
{:ok, "Alice"}
