      bsh.ExternalNameSpace

ExternalNameSpace
public class ExternalNameSpace extends NameSpace (Code)
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 (for Map), however it is not used directly by the core as other than type NameSpace, so no dependency is introduced.




Constructor Summary
public  ExternalNameSpace()
    
public  ExternalNameSpace(NameSpace parent, String name, Map externalMap)
    

Method Summary
public  voidclear()
     Clear all variables, methods, and imports from this namespace and clear all values from the external map (via Map clear()).
public  VariablecreateVariable(String name, Class type, Object value, Modifiers mods)
    
public  MapgetMap()
     Get the map view of this namespace.
protected  VariablegetVariableImpl(String name, boolean recurse)
    
public  String[]getVariableNames()
    
public  voidsetMap(Map map)
     Set the external Map which to which this namespace synchronizes. The previous external map is detached from this namespace.
public  voidunsetVariable(String name)

ExternalNameSpace
public ExternalNameSpace(NameSpace parent, String name, Map externalMap)(Code)




Method Detail
clear
public void clear()(Code)
Clear all variables, methods, and imports from this namespace and clear all values from the external map (via Map clear()).



createVariable
public Variable createVariable(String name, Class type, Object value, Modifiers mods)(Code)



getMap
public Map getMap()(Code)
Get the map view of this namespace.



getVariableImpl
protected Variable getVariableImpl(String name, boolean recurse) throws UtilEvalError(Code)



getVariableNames
