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

Methods
Modifier and Type	Method and Description
`int`	`getColumnNumber(long locationId)` Get the column number within the document, entity, or module containing a particular location
`int`	`getLineNumber(long locationId)` Get the line number within the document, entity or module containing a particular location
`String`	`getSystemId(long locationId)` Get the URI of the document, entity, or module containing a particular location

- Method Detail
  - getSystemId
```
String getSystemId(long locationId)
```
    Get the URI of the document, entity, 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, XML entity or module. For a SourceLocationProvider this will be the URI of the document or entity (the URI that would be the base URI if there were no xml:base attributes). In other cases it may identify the query or stylesheet module currently being executed.
  - getLineNumber
```
int getLineNumber(long locationId)
```
    Get the line number within the document, entity 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, entity or module, or -1 if no information is available.
  - getColumnNumber
```
int getColumnNumber(long locationId)
```
    Get the column number within the document, entity, 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, entity, or module, or -1 if this is not available
