NAME

Moose::Meta::TypeConstraint - The Moose Type Constraint metaclass

DESCRIPTION

For the most part, the only time you will ever encounter an instance of this class is if you are doing some serious deep introspection. This API should not be considered final, but it is highly unlikely that this will matter to a regular Moose user.

If you wish to use features at this depth, please come to the #moose IRC channel on irc.perl.org and we can talk :)

METHODS

meta
new
is_a_type_of ($type_name): This checks the current type name, and if it does not match, checks if it is a subtype of it.
is_subtype_of ($type_name)
compile_type_constraint
coerce ($value): This will apply the type-coercion if applicable.
check ($value): This method will return a true (1) if the $value passes the constraint, and false (0) otherwise.
validate ($value): This method is similar to check, but it deals with the error message. If the $value passes the constraint, undef will be returned. If the $value does not pass the constraint, then the message will be used to construct a custom error message.

DEPRECATED METHOD

union: This was just bad idea on my part,.. use the the Moose::Meta::TypeConstraint::Union manpage itself instead.
