org.gjt.sp.jedit.bsh.ExternalNameSpace
public class ExternalNameSpace
A namespace which maintains an external map of values held in variables in its scope. This mechanism provides a standard collections based interface to the namespace as well as a convenient way to export and view values of the namespace without the ordinary BeanShell wrappers.
Variables are maintained internally in the normal fashion to support meta-information (such as variable type and visibility modifiers), but exported and imported in a synchronized way. Variables are exported each time they are written by BeanShell. Imported variables from the map appear in the BeanShell namespace as untyped variables with no modifiers and shadow any previously defined variables in the scope. Note: this class is inherentely dependent on Java 1.2, however it is not used directly by the core as other than type NameSpace, so no dependency is introduced.

Note: this method is primarily intended for use internally. If you use this method outside of the bsh package and wish to set variables with primitive values you will have to wrap them using bsh.Primitive.
