### Constructor Detail

#### LocatorProxy

    public LocatorProxy(org.apache.xerces.xni.XMLLocator locator)

Constructs an XML locator proxy.

### Method Detail

#### getPublicId

    public java.lang.String getPublicId()

Public identifier.

Specified by:
  `getPublicId` in interface `org.xml.sax.Locator`
Returns:
  A string containing the public identifier, or null if none is available.
See Also:
  `Locator.getSystemId()`

#### getSystemId

    public java.lang.String getSystemId()

System identifier.

Specified by:
  `getSystemId` in interface `org.xml.sax.Locator`
Returns:
  A string containing the system identifier, or null if none is available.
See Also:
  `Locator.getPublicId()`

#### getLineNumber

    public int getLineNumber()

Line number.

Specified by:
  `getLineNumber` in interface `org.xml.sax.Locator`
Returns:
  The line number, or -1 if none is available.
See Also:
  `Locator.getColumnNumber()`

#### getColumnNumber

    public int getColumnNumber()

Column number.

Specified by:
  `getColumnNumber` in interface `org.xml.sax.Locator`
Returns:
  The column number, or -1 if none is available.
See Also:
  `Locator.getLineNumber()`

#### getXMLVersion

    public java.lang.String getXMLVersion()

Description copied from interface: `org.xml.sax.ext.Locator2`
Returns the version of XML used for the entity. This will normally be the identifier from the current entity's <?xml version='...' ...?> declaration, or be defaulted by the parser.

Specified by:
  `getXMLVersion` in interface `org.xml.sax.ext.Locator2`
Returns:
  Identifier for the XML version being used to interpret the entity's text, or null if that information is not yet available in the current parsing state.

#### getEncoding

    public java.lang.String getEncoding()

Description copied from interface: `org.xml.sax.ext.Locator2`
Returns the name of the character encoding for the entity. If the encoding was declared externally (for example, in a MIME Content-Type header), that will be the name returned. Else if there was an <?xml ...encoding='...'?> declaration at the start of the document, that encoding name will be returned. Otherwise the encoding will been inferred (normally to be UTF-8, or some UTF-16 variant), and that inferred name will be returned.

When an `InputSource` is used to provide an entity's character stream, this method returns the encoding provided in that input stream.

Note that some recent W3C specifications require that text in some encodings be normalized, using Unicode Normalization Form C, before processing. Such normalization must be performed by applications, and would normally be triggered based on the value returned by this method.

Encoding names may be those used by the underlying JVM, and comparisons should be case-insensitive.

Specified by:
  `getEncoding` in interface `org.xml.sax.ext.Locator2`
Returns:
  Name of the character encoding being used to interpret the entity's text, or null if this was not provided for a character stream passed through an InputSource or is otherwise not yet available in the current parsing state.
