Method Details

merge

public static void merge(ControllerStatusDTO target,
 ControllerStatusDTO toMerge)

updatePrettyPrintedFields

public static void updatePrettyPrintedFields(ControllerStatusDTO target)

merge

public static void merge(ProcessGroupStatusDTO target,
 boolean targetReadablePermission,
 ProcessGroupStatusDTO toMerge,
 boolean toMergeReadablePermission,
 String nodeId,
 String nodeAddress,
 Integer nodeApiPort)

merge

public static void merge(ProcessGroupStatusSnapshotEntity target,
 ProcessGroupStatusSnapshotEntity toMerge)

merge

public static void merge(ProcessGroupStatusSnapshotDTO target,
 boolean targetReadablePermission,
 ProcessGroupStatusSnapshotDTO toMerge,
 boolean toMergeReadablePermission)

replaceNull

private static <T> Collection<T> replaceNull(Collection<T> collection)

updatePrettyPrintedFields

public static void updatePrettyPrintedFields(ProcessGroupStatusSnapshotDTO target)

Updates the fields that are "pretty printed" based on the raw values currently set. For example, ProcessGroupStatusSnapshotDTO.setInput(String) will be called with the pretty-printed form of the FlowFile counts and sizes retrieved via ProcessGroupStatusSnapshotDTO.getFlowFilesIn() and ProcessGroupStatusSnapshotDTO.getBytesIn().

This logic is performed here, rather than in the DTO itself because the DTO needs to be kept purely getters invalid input: '&' setters - otherwise the automatic marshalling and unmarshalling to/from JSON becomes very complicated.

Parameters:

target - the DTO to update
