Class methods

-------------
|
|
INPUT_TYPES (dict):
|
|
Tell the main program input parameters of nodes.
|
|
IS_CHANGED:
|
|
optional method to control when the node is re executed.

Attributes
|
|
----------
|
|
RETURN_TYPES (`tuple`):
|
|
The type of each element in the output tulple.
|
|
RETURN_NAMES (`tuple`):
|
|
Optional: The name of each output in the output tulple.
|
|
FUNCTION (`str`):
|
|
The name of the entry-point method. For example, if `FUNCTION = "execute"` then it will run Example().execute()
|
|
OUTPUT_NODE ([`bool`]):
|
|
If this node is an output node that outputs a result/image from the graph. The SaveImage node is an example.
|
|
The backend iterates on these output nodes and tries to execute all their parents if their parent graph is properly connected.
|
|
Assumed to be False if not present.
|
|
CATEGORY (`str`):
|
|
The category the node should appear in the UI.
|
|
execute(s) -> tuple || None:
|
|
The entry point method. The name of this method must be the same as the value of property `FUNCTION`.
|
|
For example, if `FUNCTION = "execute"` then this method's name must be `execute`, if `FUNCTION = "foo"` then it must be `foo`.

Input types "INT", "STRING" or "FLOAT" are special values for fields on the node.
