Attach mechanism for java packages
javaImport function creates an item on R's
search that maps names to class names references found in
one or several "imported" java packages.
javaImport(packages = "java.lang")
- character vector containing java package paths
- An external pointer to a java specific
Currently the list of objects in the imported package is populated as new objects are found, not at creation time.
This feature is experimental. Use with caution, and don't forget to detach.

attach( javaImport( "java.util" ), pos = 2 , name = "java:java.util" ) # now we can just do something like this v <- new( Vector ) v$add( "foobar" ) ls( pos = 2 ) # or this m <- new( HashMap ) m$put( "foo", "bar" ) ls( pos = 2 ) # or even this : Collections$EMPTY_MAP
