All Implemented Interfaces:
SMBufferable

public final class SMBufferedElement
extends SMOutputElement
implements SMBufferable

Buffered version of SMOutputElement; starts its life buffered, so that it, its attributes and content are not automatically written to the underlying stream, but only when buffered instance is released.

Since the base class properly already implements most of functionality, there is not much extra to do in this class.


Field Summary
protected  boolean mIsBuffered
          All instances are initially buffered; state will be changed when instance is released.

           Note: although signature indicates we could throw an exception, this sub-class never does.
 
Method Summary
protected  boolean doOutput(SMOutputContext ctxt, boolean canClose)
          Method called to request that the entity output itself; either as much as it can without closing, or as much as it can if it is to get closed.

 void release()
          Method called to signal that the node need not be buffered any more (if not required to do so by parent/children restrictions)

Field Detail

mIsBuffered

protected boolean mIsBuffered
All instances are initially buffered; state will be changed when instance is released.

Constructor Detail

SMBufferedElement

protected SMBufferedElement(SMOutputContext ctxt,
                            java.lang.String localName,
                            SMNamespace ns)

Note: although signature indicates we could throw an exception, this sub-class never does. But since super-class in itself could, we have to declare it as potentially being thrown.

Method Detail

isBuffered

public boolean isBuffered()
Specified by:
isBuffered in interface SMBufferable
Returns:
True if this object is still buffered; false if not

release

public void release()
             throws javax.xml.stream.XMLStreamException
Description copied from interface: SMBufferable
Method called to signal that the node need not be buffered any more (if not required to do so by parent/children restrictions)

Specified by:
release in interface SMBufferable
Throws:
javax.xml.stream.XMLStreamException

doOutput

protected boolean doOutput(SMOutputContext ctxt,
                           boolean canClose)
                    throws javax.xml.stream.XMLStreamException
Description copied from class: SMOutputtable
Method called to request that the entity output itself; either as much as it can without closing, or as much as it can if it is to get closed. In both cases output can fail or be only a partial one: buffered nodes will not be output at all, and nodes with buffered children can only be partially output.

Overrides:
doOutput in class SMOutputElement
Parameters:
ctxt - Output context to use for outputting this node (and its contents)
canClose - If true, indicates that the node can (and should) be fully closed if possible. This (passing true) is usually done when a new sibling is added after a node (element/fragment); if so, current one should be recursively closed. If false, should only try to output as much as can be done without forcing closures.
Returns:
True if the whole node could be output, ie. neither it nor its children are buffered.
Throws:
javax.xml.stream.XMLStreamException
