Data::Hive::Store::Param - CGI::param-like store for Data::Hive
version 1.013
This hive store will soon be overhauled.
Basically, it expects to access a hive in an object with CGI's param method, or the numerous other things with that interface.
param
# 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.
Use a different method name on the object (default is 'param').
This method should have the "usual" behavior for a param method:
calling $obj->param with no arguments returns all param names
$obj->param
calling $obj->param($name) returns the value for that name
$obj->param($name)
calling $obj->param($name, $value) sets the value for the name
$obj->param($name, $value)
The Param store does not check the types of values, but for interoperation with other stores, sticking to simple scalars is a good idea.
This is an object providing the Data::Hive::PathPacker interface. It will convert a string to a path (arrayref) or the reverse. It defaults to a Data::Hive::PathPacker::Strict.
This is a coderef used to check whether a given parameter name exists. It will be called as a method on the Data::Hive::Store::Param object with the path name as its argument.
The default behavior gets a list of all parameters and checks whether the given name appears in it.
This is a coderef used to delete the value for a path from the hive. It will be called as a method on the Data::Hive::Store::Param object with the path name as its argument.
The default behavior is to call the delete method on the object providing the param method.
