s1tiling.libs.steps.AbstractStep

class s1tiling.libs.steps.AbstractStep(*unused_argv, **kwargs)

Bases: object

Internal root class for all actual steps.

There are several kinds of steps:

• FirstStep that contains information about input files

• Step that registers an otbapplication binding

• StoreStep that momentarilly disconnect on-memory pipeline to force storing of the resulting file.

• AnyProducerStep that executes Python functions

• ExecutableStep that executes external applications

• MergeStep that operates a rendez-vous between several steps producing files of a same kind.

The step will contain information like the current input file, the current output file… and variation points starting in _do_something() to specialize by overriding them in child classes.

New methods & Specialized methods

__init__	Constructor.
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.
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 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.
