Method Details

checkArgValueMatchesAllowedType

void checkArgValueMatchesAllowedType(List<GraphQLError> errors,
 Value<?> instanceValue,
 Type<?> allowedArgType)

Recursively inspects an argument value given an allowed type. Given the (invalid) SDL below:

directive @myDirective(arg: [[String]] ) on FIELD_DEFINITION

query { f: String @myDirective(arg: ["A String"]) }

it will first check that the `myDirective.arg` type is an array and fail when finding "A String" as it expected a nested array ([[String]]).

Parameters:

errors - validation error collector

instanceValue - directive argument value

allowedArgType - directive definition argument allowed type
