Class BuckFileSystemProvider

java.lang.Object

java.nio.file.spi.FileSystemProvider

com.facebook.buck.core.filesystems.BuckFileSystemProvider

public class BuckFileSystemProvider
extends FileSystemProvider

File system provider that replaces default Java provider for Buck-specific optimizations, mostly memory footprint on Path implementation. The provider works like a wrapper, delegating most calls to default FileSystemProvider by converting BuckUnixPath to java-default Path
