  +--org.tp23.jasper.CommandLineContext

All Implemented Interfaces:

JspCompilationContext

public class CommandLineContext

extends java.lang.Object

implements JspCompilationContext

Holds data used on a per-page compilation context that would otherwise spill over to other pages being compiled. Things like the taglib classloaders and directives.
