s1tiling.libs.steps.ExecutableStep

class s1tiling.libs.steps.ExecutableStep(exename: str, *argv, **kwargs)

Bases: _ProducerStep

Generic step for calling any external application.

Implicitly created by ExecutableStepFactory.

New methods & Specialized methods

__init__	Constructor.
_do_execute	Takes care of executing the external program.

Methods inherited from parent

execute_and_write_output	Actually produce the expected output.
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.
pipeline_name	Generate a name for the associated pipeline
shall_store	No OTB related step requires its result to be stored on disk and to break in_memory connection by default.
tmp_filename	Property that returns the name of the file produced by the current step while the OTB application, or the executable, or even the gdal function is running.

_do_call_hook(hook: Callable) → None

Variation point that takes care to execute hooks.

_do_execute(parameters, dryrun: bool) → None

Takes care of executing the external program.

property basename: str

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

execute_and_write_output(parameters, execution_parameters: Dict) → None

Actually produce the expected output. The how is still a variation point that’ll get decided in _do_execute() specializations.

While the output is produced, a temporary filename will be used as output. On successful execution, the output will be renamed to match its expected final name.

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.

property pipeline_name

Generate a name for the associated pipeline

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.

property tmp_filename: str

Property that returns the name of the file produced by the current step while the OTB application, or the executable, or even the gdal function is running. Eventually, it’ll get renamed into self.out_filename if the application succeeds.
