Methods summary

`public mixed`	# `getDataForKey( string $key )` Retrieves a data field for a specified key. The retrieved value is either cached or fetched from a data source, depending on the actual implementation. Retrieves a data field for a specified key. The retrieved value is either cached or fetched from a data source, depending on the actual implementation. Parameters `$key` Name of data field to retrieve value for. Returns mixed Retrieved data field value. Throws `Core\Exception\UndefinedKey` Requested data field does not exist. Since 3.0
`public array`	# `getDataForKeys( array $keys )` Retrieves data fields for an array of keys. Retrieves data fields for an array of keys. Parameters `$keys` Array of data field names to return values for. Returns array Dictionary of retrieved data fields. Throws `Core\Exception\UndefinedKey` Failed to resolve the data field for at least one key. Since 3.0
`public boolean`	# `issetDataForKey( string $key )` Tests, whether a data field for a given key exists. Tests, whether a data field for a given key exists.
