Class DataSourceIntrospectionModelFieldType

    • Method Detail

      • kind

        public final String kind()

        Specifies the classification of data. For example, this could be set to values like Scalar or NonNull to indicate a fundamental property of the field.

        Valid values include:

        • Scalar: Indicates the value is a primitive type (scalar).

        • NonNull: Indicates the field cannot be null.

        • List: Indicates the field contains a list.

        Returns:

      • name

        public final String name()

        The name of the data type that represents the field. For example, String is a valid name value.

        Returns:
        The name of the data type that represents the field. For example, String is a valid name value.
      • type

        public final DataSourceIntrospectionModelFieldType type()

        The DataSourceIntrospectionModelFieldType object data. The type is only present if DataSourceIntrospectionModelFieldType.kind is set to NonNull or List.

        The type typically contains its own kind and name fields to represent the actual type data. For instance, type could contain a kind value of Scalar with a name value of String. The values Scalar and String will be collectively stored in the values field.

        Returns:
        The DataSourceIntrospectionModelFieldType object data. The type is only present if DataSourceIntrospectionModelFieldType.kind is set to NonNull or List.

      • hasValues

        public final boolean hasValues()
        For responses, this returns true if the service returned a value for the Values property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.
      • values

        public final List<String> values()

        The values of the type field. This field represents the AppSync data type equivalent of the introspected field.

        Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasValues() method.

        Returns:
        The values of the type field. This field represents the AppSync data type equivalent of the introspected field.
      • hashCode

        public final int hashCode()
        Overrides:
        hashCode in class Object
      • equals

        public final boolean equals​(Object obj)
        Overrides:
        equals in class Object
      • toString

        public final String toString()
        Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.
        Overrides:
        toString in class Object
      • getValueForField

        public final <T> Optional<T> getValueForField​(String fieldName,
                                                      Class<T> clazz)
