Subject [jira] Updated: (COMDEV-39) [error]

     [ https://issues.apache.org/jira/browse/COMDEV-39?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Pons Rudy updated COMDEV-39:
----------------------------

    Description:     (was: Some minor changes in JList and DefaultListModel wich will give
better performance for huge data creation or range removal:
 - add package-private constructors DefaultListModel(Vector) and DefaultListModel(Object[])
to use directly with JList(Vector) and JList(Object[]). Theses contructors call directly the
Vector(Collection) constructor, wich is must faster than the old insertion method.
 - modify DefaultListModel.removeRange : the old method remove each element one after the
other, and each deletion cause an array copy. New method use instead subList(fromIndex, toIndex+1).clear(),
wich will result on only one array copy.)
        Summary: [error]  (was: [classlib][swing] JList and DefaultListModel performance improvement)
