When writing your own storage first check if you can use on of these storages as a base:
If you can't use one of the above you have to overwrite the following abstract methods
Abstract methods
doGetValue(string $name)
Performs the retrievement of the value.
doGetIndexedValue(string $name, mixed $index): mixed
Gets from the array element $name the entry identified by $index Note: This routine does not check, if the element is an array at all. This has do be done by the owning property
doGetElementCount(string $name): int
Gets from the array element $name the count of entries. Note: This routine does not check, if the element is an array at all. This has do be done by the owning property
doGetOffsetExists(string $name, $index): bool
Returns how many entries the array element has. Note: '
doSetValue(string $name, $value)
Performs the setting of the value
doSetIndexedValue(string $name, $index, $value)
Sets in the array property $name the element identified by $index with $value
doGetIsInitialized(string $name): bool
Returns if this storage was initialized
Optional methods
isDirty(): bool
Returns if the storage was modified. Overwrite when storage is writeable and can be modified. (for persistant storage use Persistant storage).
prepareGetValue(string $name)
Prepares the retrievement of the value
doGetKeys(string $name): array
postprocessSetValue(string $name, $value)
Perfoms action after setting the value
