NAME

SPOPS::Import::DBI::GenericOperation - Base class for delete and update import operations

SYNOPSIS

 use base qw( SPOPS::Import::DBI::GenericOperation );
 
 sub _run_operation {
     my ( $self, $op_args ) = @_;
     ...
 }

DESCRIPTION

This class provides most of the functionality necessary to delete and remove, including the main method "run()". Subclasses just need to override "_run_operation()".

METHODS

Subclassing

_run_operation( \%import_params )

Subclasses must implement this to perform the actual operation. The arguments available in "\%import_params" are:

db: Database handle
table: Name of the table
where: WHERE clause
value: Arrayref of values for use in the WHERE clause, added by "add_where_params()"

Implementations

add_where_params( @params )

Bound parameters for the WHERE clause. Each will be bound in turn.

data_from_file( $filename )

Runs "raw_data_from_file( $filename )" from SPOPS::Import to read a serialized Perl data structure from $filename, then sends the arrayref to "assign_data()" and returns the result.

data_from_fh( $filehandle )

Runs "raw_data_from_fh( $filename )" from SPOPS::Import to read a serialized Perl data structure from $filehandle, then sends the arrayref to "assign_data()" and returns the result.

assign_data( \%metadata )

Assigns the data 'table', 'where' and 'where_params' from "\%metadata" to the import object.

The additional metadata is stored under the 'extra_metadata' property of the import object.
