parameter::get_from_package_key (public)

 parameter::get_from_package_key [ -localize ] [ -boolean ] \
    -package_key package_key -parameter parameter [ -default default ]

Defined in packages/acs-tcl/tcl/parameter-procs.tcl

Gets an instance parameter for the package corresponding to package_key. Note that this makes the assumption that the package is a singleton. New packages should use global parameters instead.

Switches:

-localize

(boolean) (optional)

-boolean

(boolean) (optional)

-package_key

(required)

what package to get the parameter from. We will try to get the package_id from the package_key. This may cause an error if there are more than one instance of this package

-parameter

(required)

which parameter's value to get

-default

(optional)

what to return if we don't find a value
