XDI2 parsers

Most of the functionality of the xdi2-core component requires an XRI parser to validate XDI statements and addresses, and to decompose them into their parts. A number of different parsers are available to do this job.

Interfaces and Classes

• xdi2.core.xri3.parser.XDI3ParserRegistry: A registry that holds the currently used XRI parser.
• xdi2.core.xri3.parser.apg.XDI3ParserAPG: An XRI parser based on the recursive-descent APG parser generator.
• xdi2.core.xri3.parser.aparse.XDI3ParserAParse: An XRI parser based on the aParse parser generator.
• xdi2.core.xri3.parser.manual.XDI3ParserManual: An XRI parser implemented manually in pure Java.

Specifying a parser

XDI2 can be programmatically configured to use a certain parser:

XDI3ParserRegistry.getInstance().setParser(new XDI3ParserManual());

This can also be accomplished in the applicationContext.xml configuration file of the xdi2-server component. (See Configuration files for a description of this and other files):

<bean class="xdi2.core.xri3.parser.XDI3ParserRegistry" factory-method="getInstance">
	<property name="parser">
		<bean class="xdi2.core.xri3.parser.apg.XDI3ParserAPG" />
	</property>
</bean>
