- LocationProvider, Serializable
public class LocationMap
extends java.lang.Object
A LocationMap allocates integer codes to (systemId, lineNumber) pairs. The integer
codes are held inside an Expression object to track the location of the expression
in the source code
int | allocateLocationId(String module, int lineNumber) - Allocate a location identifier to an expression
|
int | getLineNumber(long locationId) - Get the line number corresponding to a locationId
|
String | getSystemId(long locationId) - Get the system identifier corresponding to a locationId
|
