#expand_uris(declared_uris, lookup_invocation) ⇒ Array<ResolvedLocation>

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Returns Array of resolved paths.

Parameters:

  • declared_uris (Array<String>) —

    paths as found in declaration. May contain interpolation expressions

  • lookup_invocation (Puppet::Pops::Lookup::Invocation) —

    The current lookup invocation

Returns:

def expand_uris(declared_uris, lookup_invocation)

#resolve_paths(datadir, declared_paths, lookup_invocation, is_default_config, extension = nil) ⇒ Array<ResolvedLocation>

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Returns Array of resolved paths.

Parameters:

  • datadir (Pathname) —

    The base when creating absolute paths

  • declared_paths (Array<String>) —

    paths as found in declaration. May contain interpolation expressions

  • lookup_invocation (Puppet::Pops::Lookup::Invocation) —

    The current lookup invocation

  • is_default_config (Boolean) —

    ‘true` if this is the default config and non-existent paths should be excluded

  • extension (String) (defaults to: nil) —

    Required extension such as ‘.yaml’ or ‘.json’. Use only if paths without extension can be expected

Returns:
