Gecode 3.0.0 (Default branch)
Gecode is a portable, accessible, and efficient environment for developing constraint-based systems and applications. Gecode is radically open for programming, meaning that it can be easily interfaced to other systems. It supports the programming of new propagators (as implementation of constraints), branching strategies, and search engines. New variable domains can be programmed at the same level of efficiency as finite domain and integer set variables that come predefined with Gecode. License: MIT/X Consortium License Changes:
The interface was cleaned up to use consistent parameter passing, consistent naming, a simpler Gist interface, and namespaces for operator overloading. Functionality was extended so that propagators can be non-monotonic, and branchings support tie-breaking and random variable and value selection. Some features with insufficient quality have been removed: complete set variables and reflection. Usage was simplified by using auto-linking on Windows and more commonly used filename extensions. Important aspects have been optimized, such as memory management, memory usage, and efficiency on 64-bit machines. Image

Moose::Meta::TypeConstraint::DuckType(3)		User Contributed Perl Documentation		  Moose::Meta::TypeConstraint::DuckType(3)

NAME

       Moose::Meta::TypeConstraint::DuckType - Type constraint for duck typing

VERSION

       version 2.0604

DESCRIPTION

       This class represents type constraints based on an enumerated list of required methods.

INHERITANCE

       "Moose::Meta::TypeConstraint::DuckType" is a subclass of Moose::Meta::TypeConstraint.

METHODS

       Moose::Meta::TypeConstraint::DuckType->new(%options)
	   This creates a new duck type constraint based on the given %options.

	   It takes the same options as its parent, with several exceptions. First, it requires an additional option, "methods". This should be an
	   array reference containing a list of required method names. Second, it automatically sets the parent to the "Object" type.

	   Finally, it ignores any provided "constraint" option. The constraint is generated automatically based on the provided "methods".

       $constraint->methods
	   Returns the array reference of required methods provided to the constructor.

       $constraint->create_child_type
	   This returns a new Moose::Meta::TypeConstraint object with the type as its parent.

	   Note that it does not return a "Moose::Meta::TypeConstraint::DuckType" object!
