* Interface Type Definition |

|
15
|
|
|
* When a field can return one of a heterogeneous set of types, a Interface type |
|
16
|
|
|
* is used to describe what types are possible, what fields are in common across |
|
17
|
|
|
* all types, as well as a function to determine which type is actually used |
|
18
|
|
|
* when the field is resolved. |
|
19
|
|
|
* |
|
20
|
|
|
* Example: |
|
21
|
|
|
* $EntityType = GraphQLInterfaceType([ |
|
22
|
|
|
* 'name' => 'Entity', |
|
23
|
|
|
* 'fields' => [ |
|
24
|
|
|
* 'name' => ['type' => GraphQLString()] |
|
25
|
|
|
* ] |
|
26
|

Our type inference engine has found an assignment to a property that is incompatible with the declared type of that property.
Either this assignment is in error or the assigned type should be added to the documentation/type hint for that property..
