# == Class: elasticsearch::params

#

# This class exists to

# 1. Declutter the default value assignment for class parameters.

# 2. Manage internally used module variables in a central place.

#

# Therefore, many operating system dependent differences (names, paths, ...)

# are addressed in here.

#

#

# === Parameters

#

# This class does not provide any parameters.

#

#

# === Examples

#

# This class is not intended to be used directly.
