static List<Class<?>>	findSuperClasses(ExchangeObject entity)	Finds all superclasses but excludes Object.

Method Details

findSuperClasses

public static List<Class<?>> findSuperClasses(ExchangeObject entity)

Finds all superclasses but excludes Object. This does not return interfaces. Returns a list of superclasses, or null.

Parameters:

entity -

Returns:

flattenCorrelationHierarchy

public static void flattenCorrelationHierarchy(List<? extends ExchangeObject> entities,
 Map<String,ExchangeObject> flattened)

flattenCorrelationHierarchy

public static Map<String,ExchangeObject> flattenCorrelationHierarchy(List<? extends ExchangeObject> entities)

flattenCorrelationHierarchy

public static void flattenCorrelationHierarchy(@Nullable
 ExchangeObject entity,
 @NonNull
 Map<String,ExchangeObject> result)

Recursively iterates over the properties of the entity and if they are instances of ExchangeObject this extracts them into a Map keyed by their ExchangeObject.getCorrelationId(). This also sets their parent entity's correlationId.

Parameters:

entity -

result -

resolveErrors

public static void resolveErrors(@NonNull
 Function<Throwable,DataExchangeError> dataExchangeErrorSupplier,
 @NonNull
 BatchContext<?> batchContext)

This method walks the resulting object graph from BatchContext.getSavedTopLevelEntities() that were either saved or errored, and assigns errors to BatchContext.getResponseErrors(). The assigned DataExchangeError.setPath(String) will be a JSON Path, allowing callers to traverse the responses and determine which objects in the graph each respective error belongs with.

Parameters:

dataExchangeErrorSupplier - the function that supplies the DataExchangeError based on the Throwable

batchContext - the BatchContext that contains the state of the batch, saved entities, and errors
