java.lang.Object
   org.xml.sax.helpers.LocatorImpl

LocatorImpl
public class LocatorImpl implements Locator(Code)
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

public  LocatorImpl(Locator locator)
     Copy constructor.

Method Summary
public  intgetColumnNumber()
     Return the saved column number (1-based).
public  intgetLineNumber()
     Return the saved line number (1-based).
public  StringgetPublicId()
     Return the saved public identifier.
public  StringgetSystemId()
     Return the saved system identifier.
public  voidsetColumnNumber(int columnNumber)

public  voidsetPublicId(String publicId)
     Set the public identifier for this locator.
public  voidsetSystemId(String systemId)
     Set the system identifier for this locator.


Constructor Detail
LocatorImpl
public LocatorImpl()(Code)
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)(Code)
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.




Method Detail
getColumnNumber
public int getColumnNumber()(Code)
Return the saved column number (1-based). The column number as an integer, or -1 if none is available.
See Also:   org.xml.sax.Locator.getColumnNumber
See Also:   LocatorImpl.setColumnNumber



getLineNumber
public int getLineNumber()(Code)
Return the saved line number (1-based). The line number as an integer, or -1 if none is available.
See Also:   org.xml.sax.Locator.getLineNumber
See Also:   LocatorImpl.setLineNumber



getPublicId
public String getPublicId()(Code)
Return the saved public identifier. The public identifier as a string, or null if noneis available.
See Also:   org.xml.sax.Locator.getPublicId
See Also:   LocatorImpl.setPublicId



getSystemId
public String getSystemId()(Code)
Return the saved system identifier. The system identifier as a string, or null if noneis available.
See Also:   org.xml.sax.Locator.getSystemId
See Also:   LocatorImpl.setSystemId



setColumnNumber
public void setColumnNumber(int columnNumber)(Code)
Set the column number for this locator (1-based).
Parameters:
  columnNumber - The column number, or -1 if none is available.
See Also:   LocatorImpl.getColumnNumber



setLineNumber
public void setLineNumber(int lineNumber)(Code)
Set the line number for this locator (1-based).
Parameters:
  lineNumber - The line number, or -1 if none is available.
See Also:   LocatorImpl.getLineNumber



setPublicId
public void setPublicId(String publicId)(Code)
Set the public identifier for this locator.
Parameters:
  publicId - The new public identifier, or null if none is available.
See Also:   LocatorImpl.getPublicId



setSystemId
public void setSystemId(String systemId)(Code)
Set the system identifier for this locator.
Parameters:
  systemId - The new system identifier, or null if none is available.
See Also:   LocatorImpl.getSystemId
