Class FileLocation

java.lang.Object

net.sourceforge.pmd.lang.document.FileLocation

public final class FileLocation
extends Object

Represents the coordinates of a text region, used for reporting. This provides access to the line and column positions, as well as the text file. Instances can be obtained from a TextRegion with TextDocument::toLocation.

This should replace the text coordinates methods in Node, GenericToken, and RuleViolation at least (see Reportable).
