133 MooseX::Meta::TypeConstraint::ForceCoercion \- Force coercion when validating type constraints
138 .IX Header "SYNOPSIS"
140 \& use MooseX::Types:::Moose qw/Str Any/;
141 \& use Moose::Util::TypeConstraints;
142 \& use MooseX::Meta::TypeConstraint::ForceCoercion;
144 \& # get any type constraint
147 \& # declare one or more coercions for it

164 .IX Header "DESCRIPTION"
165 This class allows to wrap any \f(CW\*(C`Moose::Meta::TypeConstraint\*(C'\fR in a way that will
166 force coercion of the value when checking or validating a value against it.
168 .IX Header "ATTRIBUTES"
169 .SS "type_constraint"
170 .IX Subsection "type_constraint"
171 The type constraint to wrap. All methods except for \f(CW\*(C`validate\*(C'\fR and \f(CW\*(C`check\*(C'\fR
172 are delegated to the value of this attribute.
176 .IX Subsection "check ($value)"
177 Same as \f(CW\*(C`Moose::Meta::TypeConstraint::check\*(C'\fR, except it will always try to
178 coerce \f(CW$value\fR before checking it against the actual type constraint. If
179 coercing fails the check will fail, too.
180 .ie n .SS "validate ($value, $coerced_ref?)"
181 .el .SS "validate ($value, \f(CW$coerced_ref\fP?)"
182 .IX Subsection "validate ($value, $coerced_ref?)"
183 Same as \f(CW\*(C`Moose::Meta::TypeConstraint::validate\*(C'\fR, except it will always try to
184 coerce \f(CW$value\fR before validating it against the actual type constraint. If
185 coercing fails the validation will fail, too.
187 If coercion was successful and a \f(CW$coerced_ref\fR references was passed, the
188 coerced value will be stored in that.
