CWorkflowTaskIO¶

class ikomia.core.pycore.CWorkflowTaskIO¶

Base class for task inputs and outputs. Each task can have as many inputs and outputs as necessary. Each input/output class must inherit this class and override the needed methods.

Import

from ikomia.core import CWorkflowTaskIO

Methods

`__init__`(arg1)	__init__( (object)self) -> None :
`clear_data`(self)	Clear the data stored in the object.
`copy_static_data`(self, io)	Copy the static data from the given input or ouput.
`from_json`(self, jsonStr)	Set input/output data from JSON formatted string.
`get_sub_io_list`(self, types)	Get the sub I/O objects of given types from a composite I/O.
`get_unit_element_count`(self)	Get the number of unit elements in terms of processing scheme.
`is_composite`(self)	Check whether I/O object is a composite one.
`is_data_available`(self)	Check whether input or output objects contain valid data.
`load`(self, path)	Load the input or output data from disk.
`save`(self, path)	Save the input or output data to disk.
`to_json`(self)	Return input/output data in JSON formatted string with default options.

Attributes

`auto_save`	Auto-save status
`data_type`	I/O data type
`dim_count`	Number of dimensions
`description`	Custom description to explain input/output type and use
`displayable`	Displayable status (Ikomia Studio)
`name`	I/O name
`source_file_path`	Path to the source file used as workflow input (if any)

See IODataType for available data types.

Details

__init__((object)arg1) → None¶

__init__( (object)self) -> None :

Default constructor

__init__( (object)self, (IODataType)data_type) -> None :

Constructor with parameters

Args:

data_type (IODataType): data type identifier

__init__( (object)self, (IODataType)data_type, (str)name) -> None :

Constructor with parameters

Args:

data_type(IODataType): data type identifier

name (str): custom name associated to input/output to give more insights to end user

__init__( (object)arg1, (CWorkflowTaskIO)arg2) -> None :

Copy constructor

clear_data((CWorkflowTaskIO)self) → None :¶

Clear the data stored in the object. Should be overriden for custom input or output.

clear_data( (CWorkflowTaskIO)self) -> None

copy_static_data((CWorkflowTaskIO)self, (CWorkflowTaskIO)io) → None :¶

Copy the static data from the given input or ouput. Static data are those which are not generated at runtime. Should be overriden for custom input or output.

Args:

CWorkflowTaskIO: input or ouput instance from which data is copied

copy_static_data( (CWorkflowTaskIO)self, (CWorkflowTaskIO)io) -> None

from_json((CWorkflowTaskIO)self, (str)jsonStr) → None :¶

Set input/output data from JSON formatted string. This method must be overriden.

Args:

jsonStr (str): data as JSON formatted string

from_json( (CWorkflowTaskIO)self, (str)jsonStr) -> None

get_sub_io_list((CWorkflowTaskIO)self, (object)types) → object :¶

Get the sub I/O objects of given types from a composite I/O.

Args:

types (list of:py:class:~ikomia.core.pycore.IODataType): sub I/O types

Returns:

list of CWorkflowTaskIO based objects: sub IO objects

get_sub_io_list( (CWorkflowTaskIO)self, (object)types) -> object

get_unit_element_count((CWorkflowTaskIO)self) → int :¶

Get the number of unit elements in terms of processing scheme. This value is used to define the number of progress steps for progress bar component in Ikomia STUDIO. For an image, the count is 1. For Z-stack volume, the count is the number of Z levels. Should be overriden for custom input or output.

Returns:

int: number of unit element to process

get_unit_element_count( (CWorkflowTaskIO)self) -> int

is_composite((CWorkflowTaskIO)self) → bool :¶

Check whether I/O object is a composite one. This method should be overriden for custom input or output.

Returns:

bool: True or False

is_composite( (CWorkflowTaskIO)self) -> bool

is_data_available((CWorkflowTaskIO)self) → bool :¶

Check whether input or output objects contain valid data. For inputs, it is the case when the previous process contains valid output data. For outputs, it is the case when the associated task had been computed at least once. Should be overriden for custom input or output.

Returns:

bool: True if data is available, False otherwise

is_data_available( (CWorkflowTaskIO)self) -> bool

load((CWorkflowTaskIO)self, (str)path) → None :¶

Load the input or output data from disk. This method must be overriden.

Args:

path (str): file path

load( (CWorkflowTaskIO)self, (str)path) -> None

save((CWorkflowTaskIO)self, (str)path) → None :¶

Save the input or output data to disk. This method must be overriden.

Args:

path (str): file path

save( (CWorkflowTaskIO)self, (str)path) -> None

to_json((CWorkflowTaskIO)self) → str :¶

Return input/output data in JSON formatted string with default options. This method must be overriden.

Returns:

str: JSON formatted string

to_json( (CWorkflowTaskIO)self) -> str

to_json( (CWorkflowTaskIO)self, (object)options) -> str :

Return input/output data in JSON formatted string. This method must be overriden. Options available depend on input/output type, a single option is available for all to set the JSON format:

[‘json_format’, ‘compact’] (default)

[‘json_format’, ‘indented’]

Args:

options (list of str): format-specific options encoded as pairs [option_name, option_value]

Returns:

str: JSON formatted string

to_json( (CWorkflowTaskIO)self, (object)options) -> str
