Examples of org.codehaus.stax2.io.Stax2Result

org.codehaus.stax2.io.Stax2Result
This is the base class for additional output results (implementations of {@link javax.xml.transform.Result}) that Stax2 {@link org.codehaus.stax2.XMLInputFactory2} implementations should support.
Note about usage by the parser factory implementations: the expectation is that at least one of methods {@link #constructWriter} and{@link #constructOutputStream} will succeed, but not necessarily both.This generally depends on type of resource being represented: for example, if the source is a StringBuilder, it is most naturally represent via {@link Writer}. For File-backed results, on the other hand, an {@link OutputStream} is the most natural access method.
Other things to note about using result {@link Writer}s and {@link OutputStream}s:
- Caller is responsible for closing any {@link Writer} and{@link OutputStream} instances requested. That is, caller ownsthese accessor objects.
- Result objects are only required to return a non-null object once: after this, if new non-null instances are returned, they must not be the same objects as returned earlier. Implementations can choose to construct new instances to the same backing data structure or resource; if so, they should document this behavior.
