public interface URIChecker

This interface defines a method for checking whether a string is considered to be a valid URI.

A user-supplied implementation of this class can be set in a customized instance of ConversionRules, which can be set in the configuration using Configuration.setConversionRules(ConversionRules)

A user-supplied implementation can be written either from scratch, or by reference to the system-supplied implementation StandardURIChecker.

Method Summary

boolean

isValidURI(CharSequence value) Check whether a given string is considered valid according to the rules of the xs:anyURI type.

Method Detail

isValidURI

boolean isValidURI(CharSequence value)

Check whether a given string is considered valid according to the rules of the xs:anyURI type.

This method is called during schema validation, and when casting string to xs:anyURI. It is not used when the xs:anyURI type is used as a return value from methods such as namespace-uri() or namespace-uri-from-QName() - in such cases no checking is applied to the name.

Parameters:

value - the string to be checked

Returns:

true if the string is considered to represent a valid URI
