      • isProtected

        public final Boolean isProtected()

        You can set this flag as true to instruct the engine not to push user-provided operations into the logical plan of the view during query planning. However, setting this flag does not guarantee that the engine will comply. Refer to the engine's documentation to understand the guarantees provided, if any.

        Returns:

      • definer

        public final String definer()

        The definer of a view in SQL.

        Returns:
        The definer of a view in SQL.

      • viewVersionId

        public final Long viewVersionId()

        The ID value that identifies this view's version. For materialized views, the version ID is the Apache Iceberg table's snapshot ID.

        Returns:
        The ID value that identifies this view's version. For materialized views, the version ID is the Apache Iceberg table's snapshot ID.

      • viewVersionToken

        public final String viewVersionToken()

        The version ID of the Apache Iceberg table.

        Returns:
        The version ID of the Apache Iceberg table.

      • refreshSeconds

        public final Long refreshSeconds()

        Auto refresh interval in seconds for the materialized view. If not specified, the view will not automatically refresh.

        Returns:
        Auto refresh interval in seconds for the materialized view. If not specified, the view will not automatically refresh.

      • lastRefreshTypeAsString

        public final String lastRefreshTypeAsString()

        Sets the method used for the most recent refresh.

        If the service returns an enum value that is not available in the current SDK version, lastRefreshType will return LastRefreshType.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from lastRefreshTypeAsString().

        Returns:
        Sets the method used for the most recent refresh.
        See Also:
        LastRefreshType

      • hasSubObjects

        public final boolean hasSubObjects()
        For responses, this returns true if the service returned a value for the SubObjects 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.

      • subObjects

        public final List<String> subObjects()

        A list of table Amazon Resource Names (ARNs).

        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 hasSubObjects() method.

        Returns:
        A list of table Amazon Resource Names (ARNs).

      • hasSubObjectVersionIds

        public final boolean hasSubObjectVersionIds()
        For responses, this returns true if the service returned a value for the SubObjectVersionIds 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.

      • subObjectVersionIds

        public final List<Long> subObjectVersionIds()

        List of the Apache Iceberg table versions referenced by the materialized view.

        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 hasSubObjectVersionIds() method.

        Returns:
        List of the Apache Iceberg table versions referenced by the materialized view.

      • hasRepresentations

        public final boolean hasRepresentations()
        For responses, this returns true if the service returned a value for the Representations 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.

      • representations

        public final List<ViewRepresentation> representations()

        A list of representations.

        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 hasRepresentations() method.

        Returns:
        A list of representations.

      • 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)
