Interface org.xml.sax.Locator
- public interface Locator
Interface for associating a SAX event with a document location.
If a SAX parser provides location information to the SAX
application, it does so by implementing this interface and then
passing an instance to the application using the document
handler's setDocumentLocator method. The application can use the
object to obtain the location of any other document handler event
in the XML source document.
Note that the results returned by the object will be valid only
during the scope of each document handler method: the application
will receive unpredictable results if it attempts to use the
locator at any other time.
SAX parsers are not required to supply a locator, but they are
very strong encouraged to do so. If the parser supplies a
locator, it must do so before reporting any other document events.
If no locator has been set by the time the application receives
the startDocument event, the application should assume that a
locator is not available.

getColumnNumber()
- Return the column number where the current document event ends.
-
getLineNumber()
- Return the line number where the current document event ends.
-
getPublicId()
- Return the public identifier for the current document event.
-
getSystemId()
- Return the system identifier for the current document event.
getPublicId
public abstract String getPublicId()
- Return the public identifier for the current document event.
This will be the public identifier
- Returns:
- A string containing the public identifier, or
null if none is available.
- See Also:
- getSystemId
getSystemId
public abstract String getSystemId()
- Return the system identifier for the current document event.
If the system identifier is a URL, the parser must resolve it
fully before passing it to the application.
- Returns:
- A string containing the system identifier, or null
if none is available.
- See Also:
- getPublicId
getLineNumber
public abstract int getLineNumber()
- Return the line number where the current document event ends.
Note that this is the line position of the first character
after the text associated with the document event.
- Returns:
- The line number, or -1 if none is available.

- getColumnNumber
getColumnNumber
public abstract int getColumnNumber()
- Return the column number where the current document event ends.
Note that this is the column number of the first
character after the text associated with the document
event. The first column in a line is position 1.
- Returns:
- The column number, or -1 if none is available.
