OptionQuery
Queries global scene options, creating an output for each option.
user
Container for user-defined plugs. Nodes should never make their own plugs here, so users are free to do as they wish.
scene
The scene to query the options from.
queries
The options to be queried - arbitrary numbers of options may be added
as children of this plug via the user interface, or via python. Each
child is a NameValuePlug
whose name
plug is the option to query,
and whose value
plug is the default value to use if the option can
not be retrieved.
out
The parent plug of the query outputs. The order of outputs corresponds
to the order of children of queries
.
