Class: Puppet::Parameter::Path

Inherits:
Puppet::Parameter show all
Defined in:
lib/puppet/parameter/path.rb

Overview

This specialized Puppet::Parameter handles validation and munging of paths. By default, a single path is accepted, and by calling Path.accept_arrays it is possible to allow an array of paths.

Instance Method Details

#unsafe_munge(paths) ⇒ String+

This is the default implementation of ‘munge`. If the concrete parameter defines a `munge` method, this default implementation will be overridden. This default implementation does not perform any munging, it just checks the one/many paths constraints. A derived implementation can perform this check as: `paths.is_a?(Array) and ! self.class.arrays?` and raise a Error.

Parameters:

  • paths (String, Array<String>) —

    one of multiple paths

Returns:

  • (String, Array<String>) —

    the given paths

Raises:

  • (Puppet::Error) —

    if the given paths does not comply with the on/many paths rule.

def unsafe_munge(paths)
  if paths.is_a?(Array) and ! self.class.arrays? then
    fail _("%{name} only accepts a single path, not an array of paths") % { name: name }
  end
  paths
end

#unsafe_validate(paths) ⇒ void

This method returns an undefined value.

This is the default implementation of the ‘validate` method. It will be overridden if the validate option is used when defining the parameter.

def unsafe_validate(paths)
  validate_path(paths)
end

#validate_path(paths) ⇒ Array<String>

Performs validation of the given paths. If the concrete parameter defines a validation method, it may call this method to perform path validation.

Returns:

  • (Array<String>) —

    the given paths

Raises:

  • (Puppet::Error) —

    if this property is configured for single paths and an array is given

  • (Puppet::Error) —

    if a path is not an absolute path
