Data Types

JitAi's data type Type elements are encapsulations of programming language native data types (such as: strings, numbers, lists, dictionaries, etc.), providing additional functionality and features, frequently used to define field types for Data Models.

The hierarchical structure of data type elements is Meta (datatypes.Meta) → Type (datatypes.xxx). Developers can also create their own Type elements or modify the official data types provided by JitAi in their own App to implement their own encapsulation.

About Data Type Object Constructor Parameters

• init parameters: Parameters that can be used in the constructor when constructing objects of a certain data type
• Inheritance relationship: Child data types inherit all init parameters from parent data types
• Parameter override: Child data types can override init parameters from parent data types
• Parameter extension: Child data types can add their own unique init parameters
• Common parameters: All data types have common init parameters by default
