public interface Location
extends SourceLocator, Locator

Saxon interface to represent a location, typically the location of an expression within a query or stylesheet. The interface combines the two JAXP interfaces SourceLocator and Locator.

Method Summary

Methods

Modifier and Type	Method and Description
int	getColumnNumber() Get the column number.
int	getLineNumber() Get the line number.
String	getPublicId() Get the Public ID
String	getSystemId() Get the system ID.
Location	saveLocation() Get an immutable copy of this Location object.

Method Detail

getSystemId

String getSystemId()

Get the system ID. This should be the system identifier of an XML external entity; if a stylesheet module comprises multiple external entities, the distinction should be retained. This means, for example, that an instruction in a stylesheet can have a different system identifier from its parent instruction. However, SAX parsers only provide location information at the element level, so when part of an XPath expression is in a different external entity from other parts of the same expression, this distinction is lost.

The system identifier of a node is in general not the same as its base URI. The base URI is affected by xml:base attributes; the system identifier is not.

Specified by:

getSystemId in interface Locator

Specified by:

getSystemId in interface SourceLocator

Returns:

the system ID, or null if the information is not available.

getPublicId

String getPublicId()

Get the Public ID

Specified by:

getPublicId in interface Locator

Specified by:

getPublicId in interface SourceLocator

Returns:

usually null

getLineNumber

int getLineNumber()

Get the line number. This line number is relative to the external entity identified by the system identifier. Line numbers start at 1. The value may be an approximation; SAX parsers only provide line number information at the level of element nodes.

Specified by:

getLineNumber in interface Locator

Specified by:

getLineNumber in interface SourceLocator

Returns:

the line number, or -1 if the information is not available.

getColumnNumber

int getColumnNumber()

Get the column number. This column number is relative to the line identified by the line number. Column numbers start at 1.

Specified by:

getColumnNumber in interface Locator

Specified by:

getColumnNumber in interface SourceLocator

Returns:

the column number, or -1 if the information is not available.

saveLocation

Location saveLocation()

Get an immutable copy of this Location object. By default Location objects may be mutable, so they should not be saved for later use. The result of this operation holds the same location information, but in an immutable form.
