public void endElement()

Specified by:

startAttribute

public void startAttribute(java.lang.Object attrType)

Write a attribute for the current element. This is only allowed immediately after a startElement.

Specified by:

startAttribute in interface Consumer

Overrides:

startAttribute in class OutPort

endAttribute

public void endAttribute()

Description copied from class: OutPort

No more attributes in this element.

Specified by:

Description copied from interface: PositionConsumer

Consume node at current position. The caller may invalidate or change the position after consume returns, so if the consumer wants to save it, it needs to copy it.

Specified by:
