as2fm.scxml_converter.scxml_entries.scxml_executable_entries.ScxmlIf

Bases: ScxmlBase

This class represents SCXML conditionals.

Class representing a conditional execution in SCXML.

Parameters:

conditional_executions – List of (condition - exec. body) pairs. Min n. pairs is one.
else_execution – Execution to be done if no condition is met.
cb_type – The kind of callback executing this SCXML entry.

`replace_strings_types_with_integer_arrays`()	Replace all string literals in the contained expressions.
`set_callback_type`(cb_type)	Set the cb type for this entry and its children.
`set_custom_data_types`(custom_data_types)	Save container with custom data types.
`set_thread_id`(thread_id)	Set the thread ID for the executable entries contained in the if object.
