=head2 __validate_type

Returns true if $value is a valid value of UML::MetaModel::Behavioral_Elements::State_Machines::ChangeEvent.

  UML::MetaModel::Behavioral_Elements::State_Machines::ChangeEvent->__typecheck($value, $msg);

Calls C<confess()> with C<$msg> if C<UML::MetaModel::Behavioral_Elements::State_Machines::ChangeEvent-E<GT>__validate_type($value)> is false.

=head2 isaChangeEvent

Returns true if receiver is a C<UML::MetaModel::Behavioral_Elements::State_Machines::ChangeEvent>.
Other receivers will return false.

=head2 isaBehavioral_Elements__State_Machines__ChangeEvent

Returns true if receiver is a C<UML::MetaModel::Behavioral_Elements::State_Machines::ChangeEvent>.
Other receivers will return false.
This is the fully qualified version of the C<isaChangeEvent> method.
