Direct Known Subclasses:

ResultTreeHandler

public abstract class QueuedEvents

extends Object

This class acts as a base for ResultTreeHandler, and keeps queud stack events. In truth, we don't need a stack, so I may change this down the line a bit.

protected boolean	m_docEnded
boolean	m_docPending Queued start element
boolean	m_elemIsEnded Flag indicating that an event is ended
boolean	m_elemIsPending Flag indicating that an event is pending.
protected int	m_eventCount The number of events queued
protected String	m_localName Local part of qualified name of the element
protected String	m_name The pending element, namespace, and local name.
protected Vector	m_namespaces Vector of namespaces for this element
protected boolean	m_nsDeclsHaveBeenAdded Flag to try and get the xmlns decls to the attribute list before other attributes are added.

protected String	m_url Namespace URL of the element

Field Detail

m_eventCount

protected int m_eventCount

The number of events queued

m_docPending

public boolean m_docPending

Queued start element

m_docEnded

protected boolean m_docEnded

m_elemIsPending

public boolean m_elemIsPending

Flag indicating that an event is pending. Public for fast access by ElemForEach.

m_elemIsEnded

public boolean m_elemIsEnded

Flag indicating that an event is ended

m_attributes

protected MutableAttrListImpl m_attributes

The pending attributes. We have to delay the call to m_flistener.startElement(name, atts) because of the xsl:attribute and xsl:copy calls. In other words, the attributes have to be fully collected before you can call startElement.

m_nsDeclsHaveBeenAdded

protected boolean m_nsDeclsHaveBeenAdded

Flag to try and get the xmlns decls to the attribute list before other attributes are added.

m_name

protected String m_name

The pending element, namespace, and local name.

m_url

protected String m_url

Namespace URL of the element

m_localName

protected String m_localName

Local part of qualified name of the element

m_namespaces

protected Vector m_namespaces

Vector of namespaces for this element

m_serializer

private Serializer m_serializer

Instance of a serializer

Constructor Detail

QueuedEvents

public QueuedEvents()

Method Detail

reInitEvents

protected void reInitEvents()

To re-initialize the document and element events

reset

public void reset()

Push document event and re-initialize events

pushDocumentEvent

void pushDocumentEvent()

Push the document event. This never gets popped.

popEvent

void popEvent()

Pop element event

setSerializer

void setSerializer(Serializer s)

This is only for use of object pooling, so that it can be reset.

Parameters:

s - non-null instance of a serializer

getSerializer

Serializer getSerializer()

This is only for use of object pooling, so the that it can be reset.

Returns:

The serializer
