getProductName

public String getProductName()
                      throws XQException

Returns:
a string indicating the product name

getSupportedXQueryEncodings

public Set getSupportedXQueryEncodings()
                                throws XQException
Description copied from interface: XQMetaData
Returns a set of java.lang.String, each of which specifies a character encoding method the XQJ implmentation supports to parse the XQuery query text.
For an example, for an XQJ impmentation which is able to parse the XQuery encoded in "UTF-8" or "UTF-16", it returns a java.util.Set of "UTF-8" and "UTF-16". If the implemetation is not able to generate a list of encodings supported, an empty set is returned. If a non-empty set is returned, the encodings returned in this set are guaranteed to be supported. Note that encodings not in the returned set might also be supported. For example, if the set has two encoding methods: 'UTF-8' and 'UTF-16', they are supported by the implementation. However, this does not mean 'Shift-Js' is not supported. It might be supported.

Specified by:
getSupportedXQueryEncodings in interface XQMetaData
Returns:
a java.util.Set of java.lang.String, each of which is an XQuery query text encoding method
