◆ getInfo()

Returns the info array.

The array is deserialized on the fly. If $cache is set to 'cache', the deserialized version is stored for later re-use.

Usually, the deserialized version is not retained to preserve memory when lots of changes need to be processed. It can however be retained to improve performance in cases where the same object is accessed several times.

Returns
array
