Data::Hive::Store::Param

CGI-like param() store for Data::Hive.

  # use default method name 'param'
  my $store = Data::Hive::Store::Param->new($obj);

  # use different method name 'info'
  my $store = Data::Hive::Store::Param->new($obj, { method => 'info' });

  # escape certain characters in keys
  my $store = Data::Hive::Store::Param->new($obj, { escape => './!' });

Return a new param() store.

Several interesting arguments can be passed in a hashref after the first (mandatory) object argument.

method
Use a different method name on the object (default is 'param').
escape
List of characters to escape (prepend '\' to) in keys.

Defaults to the separator.
separator
String to join path segments together with; defaults to either the first character of the escape option (if given) or '.'.
exists
Coderef that describes how to see if a given parameter name (separator-joined path) exists. The default is to treat the object like a hashref and look inside it.
delete
Coderef that describes how to delete a given parameter name. The default is to treat the object like a hashref and call delete on it.

  my $store = Data::Hive::Store::Param->new($obj, \%arg);

Join the path together with the separator and get it from the object.

See get.

Join path together with separator and return it.

Return true if the name of this hive is a parameter.

Delete the entry for the name of this hive and return its old value.
