Methods
__construct()
Construct a new configuration value or grouping.
- Signature: protected function __construct($name,$parent,$check_key)
- Parameters:
- string $name
The name of this configuration setting.- Default Value: null
- I2CE_MagicDataNode $parent
The parent of this configuration setting.- Default Value: null
- boolean $check_key
Defaults to true in which case we check that the key is valid.- Default Value: true
- string $name
addStorage()
Add the given storage object to this instance. The last one added is considered to be the "definitive" one -- the one whose contents should be considered correct. The first one added should be the one which has quickest access
- Signature: public function addStorage($storage)
- Parameters:
- I2CE_MagicDataStorage $storage
clearCache()
Clear caching for each of the storage mechanisms @param I2CE_MagicDataNode $node. The node we wish to remove from the cache. If null ( default) we call the clear() method for all but the last added storage mecahnism. If non-null, we call the destory() method for the node on all but the last storage mechanism.
- Signature: public function clearCache()
- Returns: boolean
destroy()
Destroy the specified node from each of the storage mechanisms
- Signature: public function destroy($node)
- Parameters:
- $node
- Returns: boolean
true on success
getPath()
Return the full path to this configuration setting.
- Signature: public function getPath($show_top)
- Parameters:
- boolean $show_top
defaults to true if we are to show the parent- Default Value: true
- boolean $show_top
- Returns: string
getPermanentStorageClass()
Gets the class of the permanent storage object (the last one added)
- Signature: public function getPermanentStorageClass()
- Returns: string
instance()
Return an instance of this class based on the index given. This will create the instance if it doesn't exist.
- Signature: static public function instance($index,$replace)
- Parameters:
- Returns: I2CE_MagicData
pathDivider()
Return the path divider for this MagicDataNode object
- Signature: protected function pathDivider()
- Returns: string
retrieve()
Retrieve the given magic data node (which should be a descendent of this instance.)
- Signature: public function retrieve($node)
- Parameters:
- I2CE_MagicDataNode $node
- Returns: array
setLocales()
- Signature: public function setLocales($locales)
- Parameters:
- $locales
store()
Store the given magic data node (which should be a descendent of this instance.) Starts storing at the last added storage mechanism until it reaches the first storage mechanism. If it fails saving at any storage mechanis, it will call the destroy method on that storage mechanism and any remaining one.
- Signature: public function store($node,$max)
- Parameters:
- I2CE_MagicDataNode $node
- integer $max
The max index of storage objects to save. Defaults to -1 meaning we store on all mechanisms- Default Value: -1
- Returns: boolean
true on success.
tearDown()
Clean up all MagicData instances. Normally, this should not be used. Primarily for unit testing.
- Signature: static public function tearDown()
