/**

* This is the primary entry point function for fulfilling GraphQL operations

|
|
* GraphQL schema.
|
|
*
|
|
* More sophisticated GraphQL servers, such as those which persist queries,
|
|
* may wish to separate the validation and execution phases to a static time
|
|
* tooling step, and a server runtime step.
|
|
*
|
|
* schema:
|
|
* The GraphQL type system to use when validating and executing a query.
|
|
* requestString:
|
|
* A GraphQL language formatted string representing the requested operation.
|
|
* rootValue:
|
|
* The value provided as the first argument to resolver functions on the top
|
|
* level type (e.g. the query object type).
|
|
* variableValues:
|
|
* A mapping of variable name to runtime value to use for all variables
|
|
* defined in the requestString.
|
|
* operationName:
|
|
* The name of the operation to use if requestString contains multiple
|
|
* possible operations. Can be omitted if requestString contains only
|
|
* one operation.
