Class JRReportSaxParserFactory

java.lang.Object
  net.sf.jasperreports.engine.xml.JRReportSaxParserFactory

All Implemented Interfaces:

JRSaxParserFactory

public class JRReportSaxParserFactory
extends java.lang.Object
implements JRSaxParserFactory

The default report SAX parser factory.

This factory creates a parser via the default SAX parser factory (javax.xml.parsers.SAXParserFactory.newInstance()).

JRXMLs are always validated using W3C XML schemas. Reports that refer the JasperReports DTD (which has been deprecated) are validated using an internal XML schema equivalent to the DTD.

To improve performance, XML schemas can be cached when using a Xerces SAX parser. See PROPERTY_CACHE_SCHEMAS.

Field Detail

PROPERTY_CACHE_SCHEMAS

public static final java.lang.String PROPERTY_CACHE_SCHEMAS

A property that determines whether XML schemas/grammars are to be cached so that they are not read/initialized each time a report is compiled.

Currently, setting this property is only effective when a Xerces XML parser is used (either a stock one from Apache or one embedded into a SUN JDK).
