getErrorValueDescriptor
default IUnionValueDescriptor<String> getErrorValueDescriptor(IValueDescriptorFactory f)
Description copied from interface:IExecutionResultDescriptor
The union descriptor for the different error types that may occur when the node is executed. Each discriminator of the union represents an error or exception type.factory.recordBuilder() // .requiredProperty("errorCode", factory.integer()) // .requiredProperty("errorMessage", factory.string()) // .requiredProperty("localizedMessage", factory.integer()); return factory.add("CONNECT_TIMEOUT", error) // .add("READ_TIMEOUT", error);
The example above uses the same data type for each error, but you can return different data depending on the error type.Note that you do not have to include a general error code. When the
execute
method of a node handler throws an unhandled (runtime) exception, the error codeCmnConst.Workflow.ERROR_CODE_GENERAL
is set automatically.- Specified by:
getErrorValueDescriptor
in interfaceIExecutionResultDescriptor
- Parameters:
f
- Factory that may be used for creating the descriptor. You may also useValueDescriptorFactory.getInstance()
if you wish to cache the descriptor in a static or instance field.- Returns:
- The value descriptor for the data that is made available to the workflow when the execution of the node failed (such as by throwing an exception).
-
getSoftErrorValueDescriptor
default IUnionValueDescriptor<String> getSoftErrorValueDescriptor(IValueDescriptorFactory f)
Description copied from interface:IExecutionResultDescriptor
The union descriptor for the differentsoft error
types that may occur when the node is executed. Each discriminator of the union represents an error or exception type.factory.recordBuilder() // .requiredProperty("errorCode", factory.integer()) // .requiredProperty("errorMessage", factory.string()) // .requiredProperty("localizedMessage", factory.integer()); return factory.add("MISSING_UPLOAD", error) // .add("CLIENT_ERROR", error);
The example above uses the same data type for each error, but you can return different data depending on the error type.@implNote This interface provides a default implementation that returns an empty descriptor for backwards compatibility so as not to break existing implementation. However, all existing implementations are strongly advised to override and implement this method. The default implementation may be removed at some point.
- Specified by:
getSoftErrorValueDescriptor
in interfaceIExecutionResultDescriptor
- Parameters:
f
- Factory that may be used for creating the descriptor. You may also useValueDescriptorFactory.getInstance()
if you wish to cache the descriptor in a static or instance field.- Returns:
- The value descriptor for the data that is made available to the workflow when the execution of the node was successful, but contains one or more soft errors.
-
getSuccessValueDescriptor
default IValueDescriptor<?,? extends IValueBuilder<?>> getSuccessValueDescriptor(IValueDescriptorFactory factory)
Description copied from interface:IExecutionResultDescriptor
Creates the value descriptor for the data that is made available to the workflow when the node was executed successfully.- Specified by:
getSuccessValueDescriptor
in interfaceIExecutionResultDescriptor
- Parameters:
factory
- Factory that may be used for creating the descriptor. Instead of the factory passed in to this method, you may also useValueDescriptorFactory.getInstance()
if you wish to cache the descriptor in a static or instance field.- Returns:
- The data provided by the node after having been executed successfully.
