public File getBaseDir()
Lifecycle: For one user's JVMs, ClassLoader and time.
This is set to:${java.io.tmpdir}/tmpDirPrefix
public File getRootDir()
Lifecycle: For one user's concurrently running JVMs and ClassLoader
tmpBaseDir/tmpRootPropValue
Use Case: Per ClassLoader files, eg. native libraries.
Old temp directories are cleaned up the next time a JVM is launched that uses TempFileCache.
public File getTempDir()
Lifecycle: Within each JVM .. use case dependent, ie. per ClassLoader
tmpRootDir/jlnMMMMMwhere jlnMMMMM is the unique filename created by File.createTempFile() without the ".tmp" extension.
