Instance Attribute Details

#childrenArray<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, }] }`
