Method Detail

getTempDir

public static java.io.File getTempDir()

Returns the temporary directory.

This method will first try to get the temp dir through TVCSystem.getTempDir().
If that method returns null for some reason, then we will get the java.io.tmpdir property.
I doub't that the latter method ever would return null, but if it does, this method returns null.

Returns:

The temp directory.
