public Attributes getCurrentAttributes() {

} Attributes that belong to the current element.
It's generally not recommended for applications to use
this method. RelaxNGCC internally removes processed attributes,
so this doesn't correctly reflect all the attributes an element
carries. |
public Locator getLocator() {
return locator;
} Gets the source location of the current event.
One can call this method from RelaxNGCC handlers to access
the line number information. Note that to |

} Called by the generated handler code when an enter element
event is consumed.
Pushes a new attribute set.
Note that attributes are NOT pushed at the startElement method,
because the processing of the enterElement event can trigger
other attribute events and etc.
This method will be called from one of handlers when it truely
consumes the enterElement event. |

} Cleans up all the data structure so that the object can be reused later.
Normally, applications do not need to call this method directly,
as the runtime resets itself after the endDocument method. |

public void setRootHandler(NGCCHandler rootHandler) {

throw new IllegalStateException();

} Sets the root handler, which will be used to parse the
root element.
This method can be called right after the object is created
or the reset method is called. You can't replace the root
handler while parsing is in progress.
Usually a generated class that corresponds to the <start>
pattern will be used as the root handler, but any NGCCHandler
can be a root handler. |
