Class Os.TmpDirFinder

java.lang.Object

org.apache.brooklyn.util.os.Os.TmpDirFinder

Enclosing class:

Os

public static class Os.TmpDirFinder
extends java.lang.Object

utility for finding a usable (writable) tmp dir, preferring java.io.tmpdir (unless it's weird, e.g. /private/tmp/xxx or /var/tmp/... as under OS X, and /tmp is valid), falling back to ~/.tmp/ (and creating that) if the others are not usable

it is weird if /tmp is not writable, but it does happen, hence this check

note you can also set java system property to force the use of a specific tmp space
