public class SMRootFragment
extends SMOutputContainer

Concrete non-buffered fragment (== container) class used as the root level output container. Root-level does not necessarily have to mean XML root level; it may also be a child context of a stream writer in which StaxMate is only used to output specific sub-trees. This class is also used as the base for the outputter that models a complete document.


Field Summary
protected  boolean mActive
          Simple state flag; children can only be added when root container is still active.

Method Summary
 boolean canOutputNewChild()
          Method called to figure out if we can just output a newly added child, without any buffering.
protected  void childReleased(SMOutputtable child)
          Method called by a child, when it is released and neither is or contains any buffered entities.
 void closeRoot()
          Method that HAS to be called when all additions have been done via StaxMate API.
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.
protected  void forceOutput(SMOutputContext ctxt)
          Method similar to SMOutputtable.doOutput(org.codehaus.staxmate.out.SMOutputContext, boolean), except that this method will always succeed in doing the output.

Method Detail

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.

Specified by:
doOutput in class SMOutputContainer
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

forceOutput

protected void forceOutput(SMOutputContext ctxt)
                    throws javax.xml.stream.XMLStreamException
Description copied from class: SMOutputtable
Method similar to SMOutputtable.doOutput(org.codehaus.staxmate.out.SMOutputContext, boolean), except that this method will always succeed in doing the output. Specifically, it will force all buffered nodes to be unbuffered, and then output.

Specified by:
forceOutput in class SMOutputContainer
Throws:
javax.xml.stream.XMLStreamException

childReleased

protected void childReleased(SMOutputtable child)
                      throws javax.xml.stream.XMLStreamException
Description copied from class: SMOutputContainer
Method called by a child, when it is released and neither is or contains any buffered entities. This should indicate that it can be output unless one of its parents or preceding siblings is buffered. Container is expected to update its own state, and then inform its own parent (if necesary) about release; this may cascade output from parents up the container stack.

Specified by:
childReleased in class SMOutputContainer
Parameters:
child - Child node that now neither is nor contains any buffered nodes.
Throws:
javax.xml.stream.XMLStreamException

canOutputNewChild

public boolean canOutputNewChild()
                          throws javax.xml.stream.XMLStreamException
Description copied from class: SMOutputContainer
Method called to figure out if we can just output a newly added child, without any buffering. It will request container to close and output all non-buffered children it has, if any; and indicate whether it was fully succesful or not.

Specified by:
canOutputNewChild in class SMOutputContainer
Returns:
True if all children (if any) were completely output; false if there was at least one buffered child that couldn't be output.
Throws:
javax.xml.stream.XMLStreamException

getPath

public void getPath(java.lang.StringBuilder sb)
Specified by:
getPath in class SMOutputContainer

closeRoot

public void closeRoot()
               throws javax.xml.stream.XMLStreamException
Method that HAS to be called when all additions have been done via StaxMate API. Since it is possible that the underlying stream writer may be buffering some parts, it needs to be informed of the closure.

Throws:
javax.xml.stream.XMLStreamException
