s1tiling.libs.steps.FirstStep

class s1tiling.libs.steps.FirstStep(*argv, **kwargs)

Bases: AbstractStep

First step instances are the pipeline staring points. They store meta data that’ll be used by the StepFactories to:

1. first tell what could be be produced

2. then to instanciate the steps

• no application executed

  New methods & Specialized methods

  __init__	Constructor.
  __repr__	Return repr(self).
  __str__	Return str(self).

  Methods inherited from parent

  release_app

  Makes sure that steps with applications are releasing the application (no-op for this class)

  Attributes and properties

  basename	Basename property will be used to generate all future output filenames.
  input_metas	Specific to MergeStep and FirstStep: returns the metas from the inputs as a list.
  is_first_step	Tells whether this step is the first of a pipeline.
  meta	Step meta data property.
  out_filename	Property that returns the name of the file produced by the current step.
  shall_store	No OTB related step requires its result to be stored on disk and to break in_memory connection by default.

property basename: str

Basename property will be used to generate all future output filenames.

property input_metas: List[Dict]

Specific to MergeStep and FirstStep: returns the metas from the inputs as a list.

property is_first_step: bool

Tells whether this step is the first of a pipeline.

property meta: Dict

Step meta data property.

property out_filename: str

Property that returns the name of the file produced by the current step.

release_app() → None

Makes sure that steps with applications are releasing the application (no-op for this class)

property shall_store: bool

No OTB related step requires its result to be stored on disk and to break in_memory connection by default.

However, the artificial Step produced by Store factory will force the result of the previous application(s) to be stored on disk.
