Overview

Note:

When making an API call, you may pass Mapping data as a hash:

{
  to_key: "EnclosedInStringProperty",
  from_path: ["EnclosedInStringProperty"],
  from_type: "EnclosedInStringProperty",
  to_type: "EnclosedInStringProperty",
  dropped: false,
  children: [
    {
      to_key: "EnclosedInStringProperty",
      from_path: ["EnclosedInStringProperty"],
      from_type: "EnclosedInStringProperty",
      to_type: "EnclosedInStringProperty",
      dropped: false,
      children: {
        # recursive Mappings
      },
    },
  ],
}

Specifies the mapping of data property keys.

#children ⇒ Array<Types::Mapping>

Only applicable to nested data structures. If you want to change the parent structure, but also one of its children, you can fill out this data strucutre. It is also `Mapping`, but its `FromPath` will be the parent's `FromPath` plus the `FromPath` from this structure.

For the children part, suppose you have the structure:

`{ “FromPath”: “OuterStructure”, “ToKey”: “OuterStructure”, “ToType”: “Struct”, “Dropped”: false, “Chidlren”: [{ “FromPath”: “inner”, “ToKey”: “inner”, “ToType”: “Double”, “Dropped”: false, }] }`

You can specify a `Mapping` that looks like:

`{ “FromPath”: “OuterStructure”, “ToKey”: “OuterStructure”, “ToType”: “Struct”, “Dropped”: false, “Chidlren”: [{ “FromPath”: “inner”, “ToKey”: “inner”, “ToType”: “Double”, “Dropped”: false, }] }`

Returns:
