Examples of net.sf.jasperreports.engine.JRTemplate

net.sf.jasperreports.engine.JRTemplate
A template that can be used by report.
Templates contain report styles that can be used by reports once the template is included in the report. This allows styles to be externalized and reused across several reports.
A template can in its turn include other templates, see {@link #getIncludedTemplates() getIncludedTemplates()}. @author Lucian Chirita (lucianc@users.sourceforge.net) @version $Id: JRTemplate.java 3033 2009-08-27 11:46:22Z teodord $ @see JRReport#getTemplates() @see JRParameter#REPORT_TEMPLATES @see JRStyleContainer#getStyleNameReference()
