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.

org.xml.sax.Locator Locator
LocatorImpl
public LocatorImpl()
Zero-argument constructor.
This will not normally be useful, since the main purpose
of this class is to make a snapshot of an existing Locator.
LocatorImpl
public LocatorImpl(Locator locator)
Copy constructor.
Create a persistent copy of the current state of a locator.
When the original locator changes, this copy will still keep
the original values (and it can be used outside the scope of
DocumentHandler methods).
- locator - The locator to copy.
