NAME

       Padre::DB::Bookmark - Padre::DB class for the bookmark table

SYNOPSIS

       TO BE COMPLETED

DESCRIPTION

       TO BE COMPLETED

METHODS

   base
         # Returns 'Padre::DB'
         my $namespace = Padre::DB::Bookmark->base;

       Normally you will only need to work directly with a table class, and only with one ORLite
       package.

       However, if for some reason you need to work with multiple ORLite packages at the same
       time without hardcoding the root namespace all the time, you can determine the root
       namespace from an object or table class with the "base" method.

   table
         # Returns 'bookmark'
         print Padre::DB::Bookmark->table;

       While you should not need the name of table for any simple operations, from time to time
       you may need it programatically. If you do need it, you can use the "table" method to get
       the table name.

   load
         my $object = Padre::DB::Bookmark->load( $id );

       If your table has single column primary key, a "load" method will be generated in the
       class. If there is no primary key, the method is not created.

       The "load" method provides a shortcut mechanism for fetching a single object based on the
       value of the primary key. However it should only be used for cases where your code trusts
       the record to already exists.

       It returns a "Padre::DB::Bookmark" object, or throws an exception if the object does not
       exist.

   select
         # Get all objects in list context
         my @list = Padre::DB::Bookmark->select;

         # Get a subset of objects in scalar context
         my $array_ref = Padre::DB::Bookmark->select(
             'where id > ? order by id',
             1000,
         );

       The "select" method executes a typical SQL "SELECT" query on the bookmark table.

       It takes an optional argument of a SQL phrase to be added after the "FROM bookmark"
       section of the query, followed by variables to be bound to the placeholders in the SQL
       phrase. Any SQL that is compatible with SQLite can be used in the parameter.

       Returns a list of Padre::DB::Bookmark objects when called in list context, or a reference
       to an "ARRAY" of Padre::DB::Bookmark objects when called in scalar context.

       Throws an exception on error, typically directly from the DBI layer.

   iterate
         Padre::DB::Bookmark->iterate( sub {
             print $_->id . "\n";
         } );

       The "iterate" method enables the processing of large tables one record at a time without
       loading having to them all into memory in advance.

       This plays well to the strength of SQLite, allowing it to do the work of loading
       arbitrarily large stream of records from disk while retaining the full power of Perl when
       processing the records.

       The last argument to "iterate" must be a subroutine reference that will be called for each
       element in the list, with the object provided in the topic variable $_.

       This makes the "iterate" code fragment above functionally equivalent to the following,
       except with an O(1) memory cost instead of O(n).

         foreach ( Padre::DB::Bookmark->select ) {
             print $_->id . "\n";
         }

       You can filter the list via SQL in the same way you can with "select".

         Padre::DB::Bookmark->iterate(
             'order by ?', 'id',
             sub {
                 print $_->id . "\n";
             }
         );

       You can also use it in raw form from the root namespace for better control.  Using this
       form also allows for the use of arbitrarily complex queries, including joins. Instead of
       being objects, rows are provided as "ARRAY" references when used in this form.

         Padre::DB->iterate(
             'select name from bookmark order by id',
             sub {
                 print $_->[0] . "\n";
             }
         );

   count
         # How many objects are in the table
         my $rows = Padre::DB::Bookmark->count;

         # How many objects
         my $small = Padre::DB::Bookmark->count(
             'where id > ?',
             1000,
         );

       The "count" method executes a "SELECT COUNT(*)" query on the bookmark table.

       It takes an optional argument of a SQL phrase to be added after the "FROM bookmark"
       section of the query, followed by variables to be bound to the placeholders in the SQL
       phrase. Any SQL that is compatible with SQLite can be used in the parameter.

       Returns the number of objects that match the condition.

       Throws an exception on error, typically directly from the DBI layer.

   new
         TO BE COMPLETED

       The "new" constructor is used to create a new abstract object that is not (yet) written to
       the database.

       Returns a new Padre::DB::Bookmark object.

   create
         my $object = Padre::DB::Bookmark->create(

             id => 'value',

             name => 'value',

             file => 'value',

             line => 'value',

         );

       The "create" constructor is a one-step combination of "new" and "insert" that takes the
       column parameters, creates a new Padre::DB::Bookmark object, inserts the appropriate row
       into the bookmark table, and then returns the object.

       If the primary key column "id" is not provided to the constructor (or it is false) the
       object returned will have "id" set to the new unique identifier.

       Returns a new bookmark object, or throws an exception on error, typically from the DBI
       layer.

   insert
         $object->insert;

       The "insert" method commits a new object (created with the "new" method) into the
       database.

       If a the primary key column "id" is not provided to the constructor (or it is false) the
       object returned will have "id" set to the new unique identifier.

       Returns the object itself as a convenience, or throws an exception on error, typically
       from the DBI layer.

   delete
         # Delete a single instantiated object
         $object->delete;

         # Delete multiple rows from the bookmark table
         Padre::DB::Bookmark->delete('where id > ?', 1000);

       The "delete" method can be used in a class form and an instance form.

       When used on an existing Padre::DB::Bookmark instance, the "delete" method removes that
       specific instance from the "bookmark", leaving the object intact for you to deal with
       post-delete actions as you wish.

       When used as a class method, it takes a compulsory argument of a SQL phrase to be added
       after the "DELETE FROM bookmark" section of the query, followed by variables to be bound
       to the placeholders in the SQL phrase. Any SQL that is compatible with SQLite can be used
       in the parameter.

       Returns true on success or throws an exception on error, or if you attempt to call delete
       without a SQL condition phrase.

   truncate
         # Delete all records in the bookmark table
         Padre::DB::Bookmark->truncate;

       To prevent the common and extremely dangerous error case where deletion is called
       accidentally without providing a condition, the use of the "delete" method without a
       specific condition is forbidden.

       Instead, the distinct method "truncate" is provided to delete all records in a table with
       specific intent.

       Returns true, or throws an exception on error.

ACCESSORS

   id
         if ( $object->id ) {

         }

       Returns true, or throws an exception on error.

SQL

       The bookmark table was originally created with the following SQL command.

         CREATE TABLE bookmark (
             id INTEGER NOT NULL PRIMARY KEY,
             name VARCHAR(255) UNIQUE NOT NULL,
             file VARCHAR(255) NOT NULL,
             line INTEGER NOT NULL
         )

SUPPORT

       Padre::DB::Bookmark is part of the Padre::DB API.
