Class BaseSaxParserFactory

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

All Implemented Interfaces:

JRSaxParserFactory

Direct Known Subclasses:

JRReportSaxParserFactory, PrintSaxParserFactory

public abstract class BaseSaxParserFactory
extends java.lang.Object
implements JRSaxParserFactory

Base SAX parser factory.

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

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).
