 |[prepend](https://dhilt.github.io/ngx-ui-scroll/#/adapter#append-prepend)|(items:&nbsp;any&nbsp;&vert;&nbsp;any[], bof?:&nbsp;boolean)|Adds items or single item to the beginning of the uiScroll dataset. If bof parameter is not set, items will be added and rendered immediately, they will be placed right before the first item in the uiScroll buffer. If bof parameter is set to true, items will be added and rendered only if the beginning of the dataset is reached; otherwise, these items will be virtualized. |
 |[check](https://dhilt.github.io/ngx-ui-scroll/#/adapter#check-size)| |Checks if any of current items changed it's size and runs a procedure to provide internal consistency and new items fetching if needed. |
 |[remove](https://dhilt.github.io/ngx-ui-scroll/#/adapter#remove)|(predicate: (item: ItemAdapter) => boolean)|Removes items from current buffer. Predicate is a function to be applied to every item presently in the buffer. Predicate must return boolean value. If predicate's return value is true, the item will be removed. _Note!_ Current implementation allows to remove only a continuous series of items per call. If you want to remove, say, 5 and 7 items, you should call the remove method twice. Removing a series of items from 5 to 7 could be done in a single call.|

Passing an options object, the direction in which inveisible items will be clipped could be specified. If no options is passed, clipping will affect both forward and backward directions. |

+Along with the documented API there are some undocumented features that can be treated as experimental. They are not tested enough and might change over time. Some of them can be found on the [experimental tab](https://dhilt.github.io/ngx-ui-scroll/#/experimental) of the demo app.

-We are not going to discuss development settings here, information about it can be obtained directly from the [source code](https://github.com/dhilt/ngx-ui-scroll/blob/master/src/component/classes/settings.ts), but the uiScroll has "debug" mode with powerful logging which can be enabled via `devSettings.debug = true`. Also, with `devSettings.immediateLog = false` the console logging will be postponed until the undocumented Adapter method `showLog` is called (`datasource.adapter.showLog()`). This case could be important from the performance view: there might be too many logs and pushing them to the console output immediately could slow down the App.
