public interface LocationProvider

LocationProvider: this interface represents an object that provides the location of elements in a source document or instructions in a stylesheet or query. A locationProvider may be passed down the Receiver pipeline as part of the PipelineConfiguration object; on the input pipeline, this will be a SaxonLocator object, on the output pipeline, it will be a LocationMap

A LocationProvider that represents locations in the source document from which the events are derived (as distinct from locations in a query or stylesheet of the instructions causing the events) will also implement the marker interface SourceLocationProvider

Method Summary

int	getColumnNumber(long locationId) Get the column number within the document or module containing a particular location
int	getLineNumber(long locationId) Get the line number within the document or module containing a particular location
java.lang.String	getSystemId(long locationId) Get the URI of the document or module containing a particular location

Method Detail

getSystemId

java.lang.String getSystemId(long locationId)

Get the URI of the document or module containing a particular location

Parameters:

locationId - identifier of the location in question (as passed down the Receiver pipeline)

Returns:

the URI of the document or module.

getLineNumber

int getLineNumber(long locationId)

Get the line number within the document or module containing a particular location

Parameters:

locationId - identifier of the location in question (as passed down the Receiver pipeline)

Returns:

the line number within the document or module.

getColumnNumber

int getColumnNumber(long locationId)

Get the column number within the document or module containing a particular location

Parameters:

locationId - identifier of the location in question (as passed down the Receiver pipeline)

Returns:

the column number within the document or module, or -1 if this is not available
