prophet::change

Prophet::Change(3pm)					User Contributed Perl Documentation				      Prophet::Change(3pm)

NAME

       Prophet::Change

DESCRIPTION

       This class encapsulates a change to a single record in a Prophet replica.

METHODS

   record_type
       The record type for the record.

   record_uuid
       The UUID of the record being changed.

   change_type
       One of "add_file", "add_dir", "update_file", "delete".

   is_resolution
       A boolean value specifying whether this change represents a conflict resolution or not.

   prop_changes [@PROPCHANGES]
       Returns a list of Prophet::PropChanges associated with this Change. Takes an optional arrayref to fully replace the set of propchanges.

   has_prop_changes
       Returns true if this change contains any Prophet::PropChanges and false if it doesn't.

   new_from_conflict $conflict
       Takes a Prophet::Conflict object and creates a Prophet::Change object representing the conflict resolution.

   add_prop_change { new => __, old => ___, name => ___ }
       Adds a new Prophet::PropChange to this Prophet::Change.

       Takes a "name", and the "old" and "new" values.

   as_hash
       Returns a reference to a representation of this change as a hash.

   as_string ARGS
       Returns a string representing this change. If $args{header_callback} is specified, the string returned from passing $self to the callback
       is prepended to the change string before it is returned.

   new_from_hashref HASHREF
       Takes a reference to a hash representation of a change (such as is returned by "as_hash" or serialized json) and returns a new
       Prophet::Change representation of it.

       This method should be invoked as a class method, not an object method.

       For example: "Prophet::Change->new_from_hashref($ref_to_change_hash)"
