Default Values

Variables (but not types) may have default values. 

To specify a default value:

"nameOfVariable": {
  "type": "string",
  "defaultValue": "someString"
},
"someOtherVariable": {
  "type": "boolean",
  "defaultValue": true"
},
"yetAnotherVariable": {
  "type": "number",
  "defaultValue": 10
}

Example 1-13 Object Variables

Object variables can also have default values:

"nameOfVariable": {
  "type": {
    "foo": "string",
    "bar": "number"
  },
  "defaultValue": {
    foo: "myDefaultFoo"
  }
}

Example 1-14 Object Variables That Reference An Application Type

Object variables that reference an application type can also have a default value for their properties:

"nameOfVariable": {
  "type": "application:myType",
  "defaultValue": {
    "foo": "myDefaultValue"
  }
}

Example 1-15 Arrays

Arrays can also have a default value for their properties:

"nameOfVariable": {
  "type": "application:myArrType",
  "defaultValue": [
    {
      "foo": "myDefaultValue"
    }
  ]
}

The following table shows how a variable is initialized, based on its type, when no default value is provided.

Type	Initial Value
String	Undefined
Number	Undefined
Boolean	Undefined
Any	Undefined
Object	{ }
Array	[ ]
Custom type	An empty object with all properties initialized according to this table
