.SH DESCRIPTION
.IX Header "DESCRIPTION"
This is a specialized type constraint class for types which require a class
name or object with a defined set of methods.
.SH API
.IX Header "API"
This class provides all of the same methods as Specio::Constraint::Simple,
with a few differences:
.SS "Specio::Constraint::AnyCan\->new( ... )"
.IX Subsection "Specio::Constraint::AnyCan->new( ... )"
The \f(CW\*(C`parent\*(C'\fR parameter is ignored if it passed, as it is always set to the
\&\f(CW\*(C`Defined\*(C'\fR type.
.PP
The \f(CW\*(C`inline_generator\*(C'\fR and \f(CW\*(C`constraint\*(C'\fR parameters are also ignored. This
class provides its own default inline generator subroutine reference.
.PP
This class overrides the \f(CW\*(C`message_generator\*(C'\fR default if none is provided.
.PP
Finally, this class requires an additional parameter, \f(CW\*(C`methods\*(C'\fR. This must be
an array reference of method names which the constraint requires. You can also
pass a single string and it will be converted to an array reference internally.
.ie n .SS $any_can\->methods
.el .SS \f(CW$any_can\fP\->methods
.IX Subsection "$any_can->methods"
Returns an array reference containing the methods this constraint requires.
.SH ROLES
.IX Header "ROLES"
This class does the Specio::Constraint::Role::IsaType,
Specio::Constraint::Role::Interface, and Specio::Role::Inlinable roles.
