Extract Lambdas¶
Extract Lambda functions matching datatype in workflows
Documentation¶
Finds and extracts top level Lambda nodes with matching datatype from provided flow files (.syx).
Input and output datatypes needs to be specified in configuration. The default value: ‘() -> ()’ represents the generic (? symbol in the GUI) type that can be any type. Examples of other datatypes are: - datasource - table - adaf - figure - text
List datatype is represented by ‘[<datatype>]’. For example, if the lambda node takes a list of tables and returns one figure, the datatype specification should be ‘[table] -> figure’ in the configuration.
The Lambda node will change its type to reflect the choosen datatype as long as it is a non-generic function type and can be matched against connected nodes. Datatypes configured that fail to satisfy the above are simply ignored.
