Constructor Detail

MinimalDTDReader

protected MinimalDTDReader(WstxInputSource input,
                           ReaderConfig cfg,
                           StreamScanner master,
                           boolean isExt)

Common initialization part of int/ext subset constructors.

Method Detail

skipInternalSubset

public static void skipInternalSubset(StreamScanner master,
                                      WstxInputSource input,
                                      ReaderConfig cfg)
                               throws java.io.IOException,
                                      WstxException

Method that just skims through structure of internal subset, but without doing any sort of validation, or parsing of contents. Method may still throw an exception, if skipping causes EOF or there's an I/O problem.

Throws:

java.io.IOException

WstxException

getLocation

public final javax.xml.stream.Location getLocation()

What DTD reader returns doesn't really matter, so let's just return perceived start location (different from what stream readers actually do)

Specified by:

getLocation in interface InputProblemReporter

Specified by:

getLocation in class StreamScanner

findEntity

public EntityDecl findEntity(java.lang.String entName)

Method that may need to be called by attribute default value validation code, during parsing....

03-Dec-2004, TSa: This is not particularly elegant: should be able to pass the information some other way. But for now it works and is necessary.

skipInternalSubset

Method that will skip through internal DTD subset, without doing any parsing, except for trying to match end of subset properly.

Throws:

java.io.IOException

WstxException
