Examples of com.ctc.wstx.util.PrefixedName

com.ctc.wstx.util.PrefixedName
Simple key Object to be used for storing/accessing of potentially namespace scoped element and attribute names.
One important note about usage is that two of the name components (prefix and local name) HAVE to have been interned some way, as all comparisons are done using identity comparison; whereas URI is NOT necessarily interned.
Note that the main reason this class is mutable -- unlike most key classes -- is that this allows reusing key objects for access, as long as the code using it knows ramifications of trying to modify a key that's used in a data structure.
Note, too, that the hash code is cached as this class is mostly used as a Map key, and hash code is used a lot.
