Abstract Value Members

  1. abstract def asLeaf: Result[Json]

    Yield the value at this Cursor rendered as Json if it is of a scalar or enum type, an error or the left hand side otherwise.

  2. abstract def asList: Result[List[Cursor]]

    Yield a list of Cursors corresponding to the elements of the value at this Cursor if it is of a list type, or an error or the left hand side otherwise.

  3. abstract def asNullable: Result[Option[Cursor]]

    Yield an optional Cursors corresponding to the value at this Cursor if it is of a nullable type, or an error on the left hand side otherwise.

    Yield an optional Cursors corresponding to the value at this Cursor if it is of a nullable type, or an error on the left hand side otherwise. The resulting Cursor will be present iff the current value is present in the model.

  4. abstract def attribute(attributeName: String): Result[Any]

    Yield the value of the attribute named attributeName of the value at this Cursor, or an error on the left hand side if there is no such attribute.

  5. abstract def field(fieldName: String): Result[Cursor]

    Yield a Cursor corresponding to the value of the field fieldName of the value at this Cursor, or an error on the left hand side if there is no such field.

  6. abstract def focus: Any

    The value at the position represented by this Cursor.

  7. abstract def hasAttribute(attributeName: String): Boolean

    Does the value at this Cursor have an attribute named attributeName?

  8. abstract def hasField(fieldName: String): Boolean

  10. abstract def isList: Boolean

    Is the value at this Cursor of a list type?

  11. abstract def isNullable: Boolean

    Is the value at this Cursor of a nullable type?

  12. abstract def narrow(subtpe: TypeRef): Result[Cursor]

    Yield a Cursor corresponding to the value at this Cursor narrowed to type subtpe, or an error on the left hand side if such a narrowing is not possible.

  13. abstract def narrowsTo(subtpe: TypeRef): Boolean

    Is the value at this Cursor narrowable to subtpe?

  14. abstract def path: List[String]

    The selection path from the root

  15. abstract def tpe: Type

    The GraphQL type of the value at the position represented by this Cursor.
