Constructor & Destructor Documentation

__construct()

snuze\Persistence\Interfaces\MapperInterface::__construct

(

StorageProviderInterface

$storage

)

A Mapper's constructor must accept a storage provider (for example, a MySQL or SQLite storage provider) implementing StorageProviderInterface.

Parameters

\snuze\Persistence\Provider\StorageProviderInterface

$storage

Implemented in snuze\Persistence\MySQL\AccountMapper, snuze\Persistence\SQLite\AccessTokenMapper, snuze\Persistence\MySQL\AccessTokenMapper, snuze\Persistence\MySQL\LinkMapper, and snuze\Persistence\MySQL\SubredditMapper.

Member Function Documentation

delete()

snuze\Persistence\Interfaces\MapperInterface::delete

(

$object

)

Delete an object from storage.

Parameters

object

$object

The object to delete

Returns

bool True on success; an exception should be thrown on error

Implemented in snuze\Persistence\MySQL\LinkMapper, snuze\Persistence\MySQL\SubredditMapper, snuze\Persistence\MySQL\AccountMapper, snuze\Persistence\SQLite\AccessTokenMapper, and snuze\Persistence\MySQL\AccessTokenMapper.

persist()

snuze\Persistence\Interfaces\MapperInterface::persist

(

$object

)

Persist the object to storage. This must support both the insertion of new objects and the updating of existing objects; implementers should use the equivalent of an "upsert" paradigm.

Parameters

object

$object

The object to persist

Returns

bool True on success; an exception should be thrown on error

Implemented in snuze\Persistence\MySQL\AccountMapper, snuze\Persistence\SQLite\AccessTokenMapper, snuze\Persistence\MySQL\AccessTokenMapper, snuze\Persistence\MySQL\LinkMapper, and snuze\Persistence\MySQL\SubredditMapper.

retrieve()

snuze\Persistence\Interfaces\MapperInterface::retrieve

(

$key

)

Retrieve an object from storage, given a unique identifier for it. The identifier used is left up to the implementer. A SubredditMapper may use the subreddit's name as the default retrieval key, whereas a LinkMapper would use the link's internal Reddit ID, etc. You can always extend the built-in mappers to add your own methods with different criteria.

Parameters

mixed

$key

A unique identifier for the object to be retrieved.

Implemented in snuze\Persistence\MySQL\LinkMapper, snuze\Persistence\MySQL\SubredditMapper, snuze\Persistence\MySQL\AccountMapper, snuze\Persistence\SQLite\AccessTokenMapper, snuze\Persistence\MySQL\AccessTokenMapper, snuze\Persistence\Interfaces\AccountMapperInterface, and snuze\Persistence\Interfaces\SubredditMapperInterface.
