Provide an optional convenience implementation of ILocator.

Inheritance
System.Object
Locator
Locator2
Assembly: Lucene.Net.Benchmark.dll
Syntax
public class Locator : object, ILocator
Remarks

This module, both source code and documentation, is in the Public Domain, and comes with NO WARRANTY. Seehttp://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:

ILocator locator;
ILocator startloc;

public void SetLocator(ILocator locator)
{
   // note the locator
   this.locator = locator;
}

public void StartDocument()
{
   // save the location of the start of the document
   // for future use.
   ILocator startloc = new Locator(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 ILocator object.

Constructors

Name Description
Locator()

Zero-argument constructor.

This will not normally be useful, since the main purpose of this class is to make a snapshot of an existing ILocator.
Locator(ILocator)

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).

Properties

ColumnNumber

Gets the saved column number (1-based). Returns the column number as an integer, or -1 if none is available.
LineNumber

Gets the saved line number (1-based). Returns the line number as an integer, or -1 if none is available.
PublicId

Gets the public identifier as a string, or null if none is available.
