java.lang.Objectnet.sf.saxon.value.Value
net.sf.saxon.value.AtomicValue
net.sf.saxon.value.QNameValue
A QName value. This implements the so-called "triples proposal", in which the prefix is retained as part of the value. The prefix is not used in any operation on a QName other than conversion of the QName to a string.

public QNameValue(NamePool namePool, int nameCode)
namePool
- The name pool containing the specified name codenameCode
- The name code identifying this name in the name poolpublic QNameValue(java.lang.String prefix, java.lang.String uri, java.lang.String localName) throws XPathException
prefix
- The prefix part of the QName (not used in comparisons). Use null or "" to represent the
default prefix.uri
- The namespace part of the QName. Use null or "" to represent the null namespace.localName

requiredType
- an integer identifying the required atomic typevalidate
- true if validation is required. If set to false, the caller guarantees that
the value is valid for the target data type, and that further validation is therefore not required.
