NAME

DataFlow::Proc::DBF - A dBase DBF converting processor

SYNOPSIS

    use DataFlow;

    # creating our flow
    my $flow = DataFlow->new([
       [ 'DBF' => { direction => 'CONVERT_FROM' } ],
    ]);


    # getting back a perl arrayref
    my $perl_struct = $flow->process( $slurped_dbf_data );


  

DESCRIPTION

This module provides a processing step for dBase (DBF) files under DataFlow. It lets you CONVERT_FROM a DBF file into a Perl data structure (in this case, an array reference) and CONVERT_TO a DBF stream, from a Perl array reference (the stream can be saved into a file for later inspection with dBase).

OPTIONS

direction

• CONVERT_FROM

  Converts FROM a DBF stream or file into a Perl array reference.

• CONVERT_TO

  Converts TO a a DBF stream or file, from a Perl array reference.

header_wanted

Saves the header of the structure into $proc->header. You can reach it via $flow->procs->[ $i ]->header, where $i is the index of the DBF processor in your flow. For example:

  my $flow = DataFlow->new([
      [ 'DBF' => { direction => 'CONVERT_FROM', header_wanted => 1 } ],
  ]);

  my $perl_data = $flow->process( $dbf_data );
  my $header    = $flow->procs->[0]->header;

dbf_opts

  my $flow = DataFlow->new([
     [ 'DBF' => {
         direction => 'CONVERT_FROM',
         dbf_opts  => { name => 'dbase.dbf' },
       }
     ],
  ]);

Sets any particular option you may want to pass to XBase. The most important one being name, in which you can specify a file name for either input (CONVERT_FROM) or output (CONVERT_TO).

DIAGNOSTICS

Error creating DBF: $MESSAGE

The conversor was unable to create a DBF file with the provided structure. Make sure you pass a matrix with lines containing the same number of elements.

CONFIGURATION AND ENVIRONMENT

DataFlow::Proc::DBF requires no configuration files or environment variables.
