Description

The javaImport function creates an item on R's search that maps names to class names references found in one or several "imported" java packages.

Usage

javaImport(packages = "java.lang")

Arguments

packages

character vector containing java package paths

Value

An external pointer to a java specific UserDefinedDatabase object

Warning

This feature is experimental. Use with caution, and don't forget to detach.

Note

Examples

## Not run: 
	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
