Method Detail

withConfig

public Managed.ManagedTransform withConfig(java.util.Map<java.lang.String,java.lang.Object> config)

Use the input Map of configuration arguments to build and instantiate the underlying transform. The map can ignore nullable parameters, but needs to include all required parameters. Check the underlying transform's schema (SchemaTransformProvider.configurationSchema()) to see which parameters are available.

withConfigUrl

public Managed.ManagedTransform withConfigUrl(java.lang.String configUrl)

Like withConfig(Map), but instead extracts the configuration arguments from a specified YAML file location.

expand

public PCollectionRowTuple expand(PCollectionRowTuple input)

Description copied from class: PTransform

Override this method to specify how this PTransform should be expanded on the given InputT.

NOTE: This method should not be called directly. Instead apply the PTransform should be applied to the InputT using the apply method.

Composite transforms, which are defined in terms of other transforms, should return the output of one of the composed transforms. Non-composite transforms, which do not apply any transforms internally, should return a new unbound output and register evaluators (via backend-specific registration methods).
