NAME

6       Hash::Layout::Level - Level definition object for Hash::Layout
7

DESCRIPTION

9       This class is used internally by Hash::Layout and is not meant to be
10       called directly. The list of hashrefs supplied to the levels param in
11       the "Hash::Layout" constructor are each used as the constructor
12       arguments passed to this class which create separate
13       "Hash::Layout::Level" objects for each level.
14
15       Please refer to the main Hash::Layout documentation for more info.

ATTRIBUTES

18   index
19       The index value of the level (first level is at index 0). This is
20       automatically supplied internally by "Hash::Layout".
21
22   name
23       An optional name/string value for this level. This is purely
24       informational and is not currently being used for anything.
25
26   delimiter
27       The character (or string) that is used by Hash::Layout when resolving
28       composite key strings in to fully qualified key paths and identifying
29       which part of the composite key should map to this level.
30
31       Defaults to a single forward-slash ("/").
32
33   registered_keys
34       An optional list (ArrayRef coerced into HashRef) of keys that are
35       associated specifically with this level. Like "delimiter", this meta-
36       data is used by Hash::Layout purely for mapping the sub-strings of a
37       composite key to a specific level.
38
39       See the implementation of filter() in DBIx::Class::Schema::Diff for the
40       best example of how "registered_keys" can be used.
