expand(PInput input)
Override this method to specify how this
PTransform should be expanded on the given
InputT . |
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.

Managed.ManagedTransform |
withConfigUrl(java.lang.String configUrl)
Like
withConfig(Map) , but instead extracts the configuration arguments from a
specified YAML file location. |

PTransform
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).
