Parameter parameter self.$(id) = $(id) $value Label label string #if $label() then 'none' else 'part'# Value value 0 $type.type Type type enum #if $type() then 'none' else 'part'# None type:raw Complex complex type:complex Float eng_float type:real Int intx type:int Long long type:int String string type:string Short ID short_id string #if not $type() all#slurp #elif $short_id() none#slurp #else part#slurp #end if len($short_id) in (0, 1) $short_id == '' or $(short_id).isalpha() This block represents a parameter to the flow graph. \ A parameter can be used to pass command line arguments into a top block. \ Or, parameters can pass arguments into an instantiated hierarchical block. The paramater value cannot depend on any variables. Leave the label blank to use the parameter id as the label. When type is not None, this parameter also becomes a command line option of the form: -[short_id] --[id] [value] The Short ID field may be left blank.
