TObject |
TDynamicDataQueue is a class used to queue arbitrary data for First-In-First-Out usage.
TDynamicDataQueue provides overloaded Push and Pop methods used to enqueue or dequeue data using an untyped buffer or a TStream instance. Use the Top method to peek at data in the queue without removing it.
Internally, TDynamicDataQueue maintains a ring queue for pointers to chunks of data using the TDynamicQueueItem type. It is optimized to reduce the amount of data movement required when adding or removing items.
TDynamicDataQueue is used to implement storage for the TCustomLazComponentQueue component in the lresources.pp unit in the Lazarus Component Library (LCL).
