Field Detail

SCRIPT_REPO

public static final String SCRIPT_REPO

Id used by all script repositories. Having a well defined string allows for various repositories to all provide the same functionality.

Parameters:

uuid - Allows setting a non-default uuid for this script service. Primarily for testing, since services rely on the repository name for finding one another.

dir - The directory used by the repo as its root. Other constructors use getDefaultScriptDir() internally.

ex -

p -
