Class LocatorImpl

java.lang.Object  |  +--org.xml.sax.helpers.LocatorImpl

All Implemented Interfaces:

Locator

public classLocatorImpl

extends java.lang.Object

implementsLocator

Provide an optional convenience implementation of Locator.

This module, both source code and documentation, is in the Public Domain, and comes withNO WARRANTY.

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

Locator

LocatorImpl

publicLocatorImpl()

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

publicLocatorImpl(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 java.lang.StringgetPublicId()

Return the saved public identifier.

Specified by:

getPublicId in interfaceLocator

Returns:

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

See Also:

Locator.getPublicId(),setPublicId(java.lang.String)

getSystemId

public java.lang.StringgetSystemId()

Return the saved system identifier.

Specified by:

getSystemId in interfaceLocator

Returns:

The system identifier as a string, or null if none is available.

See Also:

Locator.getSystemId(),setSystemId(java.lang.String)

getLineNumber

public intgetLineNumber()

Return the saved line number (1-based).

Specified by:

getLineNumber in interfaceLocator

Returns:

The line number as an integer, or -1 if none is available.

See Also:

Locator.getLineNumber(),setLineNumber(int)

getColumnNumber

public intgetColumnNumber()

Return the saved column number (1-based).

Specified by:

getColumnNumber in interfaceLocator

Returns:

The column number as an integer, or -1 if none is available.

See Also:

Locator.getColumnNumber(),setColumnNumber(int)

setPublicId

public voidsetPublicId(java.lang.String publicId)

Set the public identifier for this locator.

Parameters:

publicId - The new public identifier, or null if none is available.

See Also:

setSystemId

public voidsetSystemId(java.lang.String systemId)

Set the system identifier for this locator.

Parameters:

systemId - The new system identifier, or null if none is available.

setLineNumber

public voidsetLineNumber(int lineNumber)

Set the line number for this locator (1-based).

Parameters:

lineNumber - The line number, or -1 if none is available.
