Declare::Constraints::UserDeclare::Constraints::Simple::Library::Exportable(3)NAMEDeclare::Constraints::Simple::Library::Exportable - Export Facilities
DESCRIPTION
This contains the constraint export logic of the module.
METHODS
import($flag, @args)
use ExportableModule->All;
# or
use ExportableModule-Only => qw(Constraint1 ...);
# or
use ExportableModule-Library;
Exports the constraints to the calling namespace. This includes all
libraries in Declare::Constraints::Simple::Library, that package itself
(providing all default constraints) or Declare::Constraints::Simple
itself as a shortcut.
Possible flags are
All Imports all constraints registered in the class and its base
classes.
Only
use Declare::Constraints::Simple::Library::Scalar-Only => 'HasLength';
The above line would only import the "HasLength" constraints from
the "Scalar" default library. Note however, that you could also
just have said
use Declare::Constraints::Simple-Only => 'HasLength';
as both "::Simple" and "::Simple::Library" work on all default
libraries.
Library
You can use this to define your own constraint library. For more
information, see Declare::Constraints::Simple::Library::Base.
_build_handle_map()
Internal method to build constraint-to-class mappings.
_export_all($target, $handle_map)
Internal method. Exports all handles in $handle_map into the $target
namespace.
_export_these($target, $handle_map, @constraints)
Internal method. Exports all @constraints from $handle_map into the
$target namespace.
