 org.jfree.report.data.GlobalView
| GlobalView | | final public class GlobalView implements DataRow(Code) | | The global view holds all *named* data columns. Expressions which have no
name will not appear here. There is a slot for each name - if expressions
share the same name, the last name wins.
This acts as some kind of global variables heap - which allows named
functions to export their values to a global space.
This datarow is optimized for named access - the sequential access is only
generated when absolutly needed.
