LocatorImpl (Java Platform SE 6) (original) (raw)
org.xml.sax.helpers
Class LocatorImpl
java.lang.Object
org.xml.sax.helpers.LocatorImpl
All Implemented Interfaces:
Direct Known Subclasses:
public class LocatorImpl
extends Object
implements 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.
Since:
SAX 1.0

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).
Parameters:
locator - The locator to copy.

getPublicId
public String getPublicId()
Return the saved public identifier.
Specified by:
[getPublicId](../../../../org/xml/sax/Locator.html#getPublicId%28%29) in interface [Locator](../../../../org/xml/sax/Locator.html "interface in org.xml.sax")
Returns:
The public identifier as a string, or null if none is available.
See Also:
Locator.getPublicId(), setPublicId(java.lang.String)
getSystemId
public String getSystemId()
Return the saved system identifier.
Specified by:
[getSystemId](../../../../org/xml/sax/Locator.html#getSystemId%28%29) in interface [Locator](../../../../org/xml/sax/Locator.html "interface in org.xml.sax")
Returns:
The system identifier as a string, or null if none is available.
See Also:
Locator.getSystemId(), setSystemId(java.lang.String)
getLineNumber
public int getLineNumber()
Return the saved line number (1-based).
Specified by:
[getLineNumber](../../../../org/xml/sax/Locator.html#getLineNumber%28%29) in interface [Locator](../../../../org/xml/sax/Locator.html "interface in org.xml.sax")
Returns:
The line number as an integer, or -1 if none is available.
See Also:
Locator.getLineNumber(), setLineNumber(int)
getColumnNumber
public int getColumnNumber()
Return the saved column number (1-based).
Specified by:
[getColumnNumber](../../../../org/xml/sax/Locator.html#getColumnNumber%28%29) in interface [Locator](../../../../org/xml/sax/Locator.html "interface in org.xml.sax")
