Logic Nodes

Branching and comparison: switches route execution based on a value, routers pick one of several paths, and the boolean nodes combine conditions. See Switches for how conditional flow works in graphs.

AND Router

core/ANDRouter

Route a value based on AND logic where all of a - d are truthy (if connected)

Truthy values are considered as True, False and None are considered as False

If a value is provided, it will be returned if the result is True If no value is provided, True will be returned on the output activated through the result, the other output will be deactivated

Inputs

Input	Type	Description
`a`	`bool`	flag A
`b`	`bool`	flag B
`c`	`bool`	flag C
`d`	`bool`	flag D
`value`	`any`	value to route to the activated output (optional)

Outputs

Output	Type	Description
`yes`	`any`	if the result is True
`no`	`any`	if the result is False

Apply Default

core/ApplyDefault

Applies a default value if the input value is UNRESOLVED

Inputs

Input	Type	Description
`value`	`any`	(optional) value to apply the default to
`default`	`any`	the default value to apply

Outputs

Output	Type	Description
`value`	`any`	the value with the default applied

Properties

Property	Type	Default	Description
`apply_on_none`	`bool`	`False`	If True, the default will be applied if the value is None
`apply_on_unresolved`	`bool`	`True`	If True, the default will be applied if the value is UNRESOLVED

As Bool

core/AsBool

Converts a value to a boolean

This specfically handles UNRESOLVED by casting it to a default value

Inputs

Input	Type	Description
`value`	`any`	(optional) value to convert

Outputs

Output	Type	Description
`value`	`bool`	boolean value

Properties

Property	Type	Default	Description
`default`	`bool`	`False`	The default value to return if the value is UNRESOLVED

Case

core/Case

Route a value based on attribute value check (exact match) like a switch / case statement.

When no attribute_name is set, the value is cast to a string before comparison, so case values should be given as strings.

Inputs

Input	Type	Description
`value`	`any`	value to check

Outputs

Output	Type	Description
`a`	`any`	if the value matches case A
`b`	`any`	if the value matches case B
`c`	`any`	if the value matches case C
`d`	`any`	if the value matches case D
`none`	`any`	if the value matches no case

Properties

Property	Type	Default	Description
`attribute_name`	`str`	`""`	The attribute name to check for the value
`case_a`	`str`	`""`	The value to compare to for case A
`case_b`	`str`	`""`	The value to compare to for case B
`case_c`	`str`	`""`	The value to compare to for case C
`case_d`	`str`	`""`	The value to compare to for case D

Case Router

core/CaseRouter

Route one of several input values based on a check value match, like a switch / case statement with a single output.

The check value (or its attribute) is cast to a string before comparison, so case values should be given as strings. The input of the first matching case is routed to the value output; if no case matches, the default input is routed instead.

Inputs

Input	Type	Description
`check`	`any`	value to check
`a`	`any`	(optional) value to route for case A
`b`	`any`	(optional) value to route for case B
`c`	`any`	(optional) value to route for case C
`d`	`any`	(optional) value to route for case D
`default`	`any`	(optional) value to route if no match

Outputs

Output	Type	Description
`value`	`any`	the value of the matching case or default

Properties

Property	Type	Default	Description
`attribute_name`	`str`	`""`	The attribute name to check for the check value
`case_a`	`str`	`""`	The value to compare to for case A
`case_b`	`str`	`""`	The value to compare to for case B
`case_c`	`str`	`""`	The value to compare to for case C
`case_d`	`str`	`""`	The value to compare to for case D

Coallesce

core/Coallesce

Takes a list of values and returns the first truthy value

A value is considered truthy unless it is None, False, or UNRESOLVED (0 and empty strings count as truthy). If no input qualifies, the output is UNRESOLVED.

Inputs

Input	Type	Description
`a`	`any`	(optional) value A
`b`	`any`	(optional) value B
`c`	`any`	(optional) value C
`d`	`any`	(optional) value D

Outputs

Output	Type	Description
`value`	`any`	the first truthy value

Invert

core/Invert

Takes a boolean input and inverts it

Inputs

Input	Type	Description
`value`	`bool`	boolean value

Outputs

Output	Type	Description
`value`	`bool`	inverted boolean value

Make Bool

core/MakeBool

Creates a boolean value

Outputs

Output	Type	Description
`value`	`bool`	boolean value

Properties

Property	Type	Default	Description
`value`	`bool`	`True`	The boolean value

OR Router

core/ORRouter

Route a value based on OR logic where any of a - d is truthy (if connected)

Truthy values are considered as True, False and None are considered as False

If a value is provided, it will be returned if the result is True If no value is provided, True will be returned on the output activated through the result, the other output will be deactivated
