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 (optional, boolean)
-boolean (optional, boolean)
-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
