Attach mechanism for java packages

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.

Keywords
programming
Usage
javaImport(packages = "java.lang")
Arguments
packages
character vector containing java package paths
Value

  • An external pointer to a java specific UserDefinedDatabase object

Note

Currently the list of objects in the imported package is populated as new objects are found, not at creation time.

Warning

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