Class LocatorImpl
- Locator
Provide an optional convenience implementation of Locator.
This module, both source code and documentation, is in the
Public Domain, and comes with NO WARRANTY.
See http://www.saxproject.org
for further information.
This class is available mainly for application writers, who
can use it to make a persistent snapshot of a locator at any
point during a document parse:
Locator locator;
Locator startloc;
public void setLocator (Locator locator)
{
// note the locator
this.locator = locator;
}
public void startDocument ()
{
// save the location of the start of the document
// for future use.
Locator startloc = new LocatorImpl(locator);
}
Normally, parser writers will not use this class, since it
is more efficient to provide location information only when
requested, rather than constantly updating a Locator object.

of this class is to make a snapshot of an existing Locator.
