Class BaseFileVisitor

java.lang.Object

java.nio.file.SimpleFileVisitor<Path>

engineering.swat.watch.impl.overflows.BaseFileVisitor

All Implemented Interfaces:

FileVisitor<Path>

Direct Known Subclasses:

MemorylessRescanner.Generator

public class BaseFileVisitor
extends SimpleFileVisitor<Path>

Base extension of SimpleFileVisitor, intended to be further specialized by subclasses to auto-handle WatchEvent.Kind.OVERFLOW events. In particular, method walkFileTree() of this class internally calls Files.walkFileTree(java.nio.file.Path, java.util.Set<java.nio.file.FileVisitOption>, int, java.nio.file.FileVisitor<? super java.nio.file.Path>) to visit the file tree that starts at path, with a maximum depth inferred from scope. Subclasses can be specialized, for instance, to generate synthetic events or index a file tree.
