Instance Method Details

#all_fields ⇒ Array<GraphQL::Field>

These fields don’t have instrumenation applied

Returns:

  • (Array<GraphQL::Field>) —

    All fields, including ones inherited from interfaces

See Also:

  • Get fields with instrumentation

#get_field(field_name) ⇒ GraphQL::Field

This fields doesnt have instrumenation applied

Returns:

  • (GraphQL::Field) —

    The field definition for field_name (may be inherited from interfaces)

#implements(interfaces, inherit: false, **options) ⇒ Object

Declare that this object implements this interface. This declaration will be validated when the schema is defined.

Parameters:

  • interfaces (Array<GraphQL::Interface>) —

    add a new interface that this type implements

  • inherits (Boolean) —

    If true, copy the interfaces’ field definitions to this type
