Class XMLStreamWriterFactory

java.lang.Object

com.sun.xml.ws.api.streaming.XMLStreamWriterFactory

Direct Known Subclasses:

XMLStreamWriterFactory.Default, XMLStreamWriterFactory.NoLock, XMLStreamWriterFactory.Zephyr

public abstract class XMLStreamWriterFactory
extends Object

Factory for XMLStreamWriter.

This wraps XMLOutputFactory and allows us to reuse XMLStreamWriter instances when appropriate.

Method Details

doCreate

public abstract XMLStreamWriter doCreate(OutputStream out)

See create(OutputStream) for the contract. This method may be invoked concurrently.

doCreate

public abstract XMLStreamWriter doCreate(OutputStream out,
 String encoding)

See create(OutputStream,String) for the contract. This method may be invoked concurrently.

doRecycle

public abstract void doRecycle(XMLStreamWriter r)

See recycle(XMLStreamWriter) for the contract. This method may be invoked concurrently.

recycle

public static void recycle(XMLStreamWriter r)

Should be invoked when the code finished using an XMLStreamWriter.

If the recycled instance implements XMLStreamWriterFactory.RecycleAware, XMLStreamWriterFactory.RecycleAware.onRecycled() will be invoked to let the instance know that it's being recycled.

It is not a hard requirement to call this method on every XMLStreamReader instance. Not doing so just reduces the performance by throwing away possibly reusable instances. So the caller should always consider the effort it takes to recycle vs the possible performance gain by doing so.

This method may be invked by multiple threads concurrently.

Parameters:

r - The XMLStreamReader instance that the caller finished using. This could be any XMLStreamReader implementation, not just the ones that were created from this factory. So the implementation of this class needs to be aware of that.

get

@NotNull
public static XMLStreamWriterFactory get()

Gets the singleton instance.

set

public static void set(@NotNull
 XMLStreamWriterFactory f)

Overrides the singleton XMLStreamWriterFactory instance that the JAX-WS RI uses.

Parameters:

f - must not be null.

create

public static XMLStreamWriter create(OutputStream out)

Short-cut for create(OutputStream, String) with UTF-8.

create

public static XMLStreamWriter create(OutputStream out,
 String encoding)
