Class ListInstalledComponentsResponse

    • Method Detail

      • hasInstalledComponents

        public final boolean hasInstalledComponents()
        For responses, this returns true if the service returned a value for the InstalledComponents 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.
      • installedComponents

        public final List<InstalledComponent> installedComponents()

        A list that summarizes each component on the core device.

        Greengrass nucleus v2.7.0 or later is required to get an accurate lastStatusChangeTimestamp response. This response can be inaccurate in earlier Greengrass nucleus versions.

        Greengrass nucleus v2.8.0 or later is required to get an accurate lastInstallationSource and lastReportedTimestamp response. This response can be inaccurate or null in earlier Greengrass nucleus versions.

        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 hasInstalledComponents() method.

        Returns:
        A list that summarizes each component on the core device.

        Greengrass nucleus v2.7.0 or later is required to get an accurate lastStatusChangeTimestamp response. This response can be inaccurate in earlier Greengrass nucleus versions.

        Greengrass nucleus v2.8.0 or later is required to get an accurate lastInstallationSource and lastReportedTimestamp response. This response can be inaccurate or null in earlier Greengrass nucleus versions.

      • nextToken

        public final String nextToken()
