NAME

Palm::Raw - Handler for "raw" Palm databases.

SYNOPSIS

Top

    use Palm::Raw;

For standalone programs.

    use Palm::Raw();
    @ISA = qw( Palm::Raw );

For Palm::PDB helper modules.

DESCRIPTION

Top

The Raw PDB handler is a helper class for the Palm::PDB package. It is intended as a generic handler for any database, or as a fallback default handler.

If you have a standalone program and want it to be able to parse any type of database, use

    use Palm::Raw;

If you are using Palm::Raw as a parent class for your own database handler, use

    use Palm::Raw();

If you omit the parentheses, Palm::Raw will register itself as the default handler for all databases, which is probably not what you want.

The Raw handler does no processing on the database whatsoever. The AppInfo block, sort block, records and resources are simply strings, raw data from the database.

By default, the Raw handler only handles record databases (.pdb files). If you want it to handle resource databases (.prc files) as well, you need to call

    &Palm::PDB::RegisterPRCHandlers("Palm::Raw", "");

in your script.

AppInfo block

    $pdb->{appinfo}

This is a scalar, the raw data of the AppInfo block.

Sort block

    $pdb->{sort}

This is a scalar, the raw data of the sort block.

Records

    @{$pdb->{records}};

Each element in the "records" array is a reference-to-hash. In addition to the standard keys ("attributes", "category", and "id"), this hash contains the key "data"; its value is a string with the raw record data.

Resources

    @{$pdb->{resources}};

Each element in the "resources" array is a reference-to-hash. In addition to the standard keys ("type" and "id"), it contains the key "data"; its value is a string with the raw resource data.

# Palm::Raw.pm
# 
# Perl class for dealing with "raw" PDB databases. A "raw" database is
# one where the AppInfo and sort blocks, and all of the
# records/resources, are just strings of bytes.
# This is useful as a default PDB handler, for cases where you want to
# be able to handle any kind of database in a generic fashion.
# You may also find it useful to subclass this class, for cases where
# you don't care about every type of thing in a database.
