If else composer

Fluent If/Else builder for Composer.

This module defines IfElseComposer, a small builder used by Composer to add an if/else conditional step fluently.

Note

This builder is not meant to be instantiated directly by users. Use Composer.when(...) to obtain an instance and complete it with .then(...), .otherwise(...), and .end().

IfElseComposer(parent, condition, output_state=None, input_map=None, retry_config=None, error_handler=None, cache_store=None, cache_config=None, name=None)

Fluent builder for an if/else conditional.

Usage

composer.when(cond).then(if_branch).otherwise(else_branch).end()

After setting both branches, call .end() to append the conditional step and return back to the parent Composer.

Initialize the IfElseComposer.

Parameters:

Name	Type	Description	Default
parent	Composer	The parent composer instance.	required
condition	Component | Callable[[dict[str, Any]], bool]	The condition to evaluate.	required
output_state	str | None	Optional state key to store condition result. Defaults to None.	None
input_map	InputMapSpec | None	Unified input mapping for the condition. Defaults to None.	None
retry_config	RetryConfig | None	Retry configuration. Defaults to None.	None
error_handler	BaseStepErrorHandler | None	Error handler. Defaults to None.	None
cache_store	BaseCache | None	Optional cache store. Defaults to None.	None
cache_config	dict[str, Any] | None	Optional cache config. Defaults to None.	None
name	str | None	Optional name for the resulting step. Defaults to None, in which case a name will be auto-generated with the prefix "IfElse_".	None

end()

Finalize and append the conditional step to the parent composer.

Returns:

Name	Type	Description
Composer	Composer	The parent composer for continued chaining.

otherwise(branch)

Define the branch to execute when the condition is false.

Parameters:

Name	Type	Description	Default
branch	BasePipelineStep | list[BasePipelineStep]	The step(s) for the false branch.	required

Returns:

Name	Type	Description
Self	Self	The builder instance for chaining.

then(branch)

Define the branch to execute when the condition is true.

Parameters:

Name	Type	Description	Default
branch	BasePipelineStep | list[BasePipelineStep]	The step(s) for the true branch.	required

Returns:

Name	Type	Description
Self	Self	The builder instance for chaining.
