org.xml.sax.helpers.LocatorImpl
- Locator
public class LocatorImpl
extends java.lang.Object
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.

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.
setColumnNumber
public void setColumnNumber(int columnNumber)
Set the column number for this locator (1-based).
columnNumber
- The column number, or -1 if none is available.
getColumnNumber()
setLineNumber
public void setLineNumber(int lineNumber)
Set the line number for this locator (1-based).
lineNumber
- The line number, or -1 if none is available.
getLineNumber()
setPublicId
public void setPublicId(String publicId)
Set the public identifier for this locator.
publicId
- The new public identifier, or null
if none is available.
getPublicId()
setSystemId
public void setSystemId(String systemId)
Set the system identifier for this locator.
systemId
- The new system identifier, or null
if none is available.
getSystemId()
