apache_beam.options.pipeline_options_validator module

Pipeline options validator.

For internal use only; no backwards-compatibility guarantees.

class apache_beam.options.pipeline_options_validator.PipelineOptionsValidator(options, runner)

Bases: future.types.newobject.newobject

Validates PipelineOptions.

Goes through a list of known PipelineOption subclassess and calls:

validate(validator)

if one is implemented. Aggregates a list of validation errors from all and returns an aggregated list.

validate()

Calls validate on subclassess and returns a list of errors.

validate will call validate method on subclasses, accumulate the returned list of errors, and returns the aggregate list.

Returns:Aggregate list of errors after all calling all possible validate methods.

is_service_runner()

True if pipeline will execute on the Google Cloud Dataflow service.

is_full_string_match(pattern, string)

Returns True if the pattern matches the whole string.

validate_gcs_path(view, arg_name)

Validates a GCS path against gs://bucket/object URI format.

validate_cloud_options(view)

Validates job_name and project arguments.

validate_optional_argument_positive(view, arg_name)

Validates that an optional argument (if set) has a positive value.

validate_test_matcher(view, arg_name)

Validates that on_success_matcher argument if set.

Validates that on_success_matcher is unpicklable and is instance of hamcrest.core.base_matcher.BaseMatcher.
