Types

Types define structure in much the same way as variables.

Types can be defined at the application, flow, and page level, and can be referenced by variables.

Types can be defined once at the application level in the application model. This can help you to avoid using the same structure repeatedly in different variables.

Example 1-4 Using Types in the Application Model

types: {
  "myType": {
    "foo": "string",
    "bar": "number"
  }
}

Example 1-5 Referencing Types in a Variable

To reference types in a variable, prefix the type with 'application:', for example: 

"nameOfVariable": {
  "type": "application:myType"
}

Page

A page can access a type defined in itself, or the parent flow, or the application.

Definition Result 
"nameOfVariable": {
  "type": "myType"
}
 Uses the type named myType defined in the page. 
"nameOfVariable": {
  "type": "page:myType"
}
 Uses the type named myType defined in the page (same as no prefix). 
"nameOfVariable": {
  "type": "flow:myType"
}
 Uses the type named myType defined in the flow containing this page. 
"nameOfVariable": {
  "type": "application:myType"
}
 Uses the type named myType defined in the application.

Flow

A flow can access a type defined in itself, or the application.

Definition Result 
"nameOfVariable": {
  "type": "myType"
}
 Uses the type named myType defined in the flow. 
"nameOfVariable": {
  "type": "flow:myType"
}
 Uses the type named myType defined in the flow (same as no prefix). 
"nameOfVariable": {
  "type": "application:myType"
}
 Uses the type named myType defined in the application.

Application

An application can access a type defined in itself.

Definition Result 
"nameOfVariable": {
  "type": "myType"
}
 Uses the type named myType defined in the application. 
"nameOfVariable": {
  "type": "application:myType"
}
 Uses the type named myType defined in the application (same as no prefix).

Type References

An existing type can be used inside a type definition.

"types": {
  "region": {
    "facility": {
      "id": "string",
      "name": "string",
      "detail": "string"
    },
  "address": "flow:address",  <-- Use address defined in the parent flow
  "facilities": "facility[]"  <-- Use facility defined above
  }
}
