 |[resume](https://dhilt.github.io/ngx-ui-scroll/#adapter#pause-resume)| |Resumes the Scroller if it was paused. |
 |[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. |
 |[clip](https://dhilt.github.io/ngx-ui-scroll/#adapter#clip)|(options: {<br>&nbsp;&nbsp;forwardOnly?:&nbsp;boolean,<br>&nbsp;&nbsp;backwardOnly?:&nbsp;boolean<br>})|Removes out-of-viewport items on demand. The direction in which invisible items should be clipped can be specified by passing an options object. If no options is passed (or both properties are set to _true_), clipping will occur in both directions. |
-|[append](https://dhilt.github.io/ngx-ui-scroll/#adapter#append-prepend)|(options: {<br>&nbsp;&nbsp;items:&nbsp;MyItem[],<br>&nbsp;&nbsp;eof?:&nbsp;boolean,<br>&nbsp;&nbsp;virtualize?:&nbsp;boolean<br>&nbsp;&nbsp;decrease?:&nbsp;boolean<br>})|Adds _items_ to the end of the Scroller's buffer. If neither _eof_ nor _virtualize_ flag is set, items are inserted and rendered after the last item in the DOM. If _eof_ is _true_, rendering occurs only when the right border of the buffer aligns with the right border of the dataset (end-of-file is reached). Otherwise, items are added to the dataset but not rendered (they are virtualized). Setting the _virtualize_ flag enables hard virtualization: new _items_ will be rendered even if EOF has been reached. Indexes increase by default. If _decrease_ is set to true, indexes are decremented. See also [bof/eof](https://dhilt.github.io/ngx-ui-scroll/#adapter#bof-eof). |
-|[prepend](https://dhilt.github.io/ngx-ui-scroll/#adapter#append-prepend)|(options: {<br>&nbsp;&nbsp;items:&nbsp;MyItem[],<br>&nbsp;&nbsp;bof?:&nbsp;boolean,<br>&nbsp;&nbsp;virtualize?:&nbsp;boolean<br>&nbsp;&nbsp;increase?:&nbsp;boolean<br>})|Adds _items_ to the beginning of the Scroller's buffer. If neither _bof_ nor _virtualize_ flag is set, items are inserted and rendered before the first item in the DOM. If _bof_ is true, rendering occurs only when the left border of the buffer aligns with the left border of the dataset (begin-of-file is reached). Otherwise, items are added to the dataset but not rendered (they are virtualized). Setting the _virtualize_ flag enables hard virtualization: new items will be rendered even if BOF has been reached. Indexes decrease by default. If _increase_ is set to true, indexes are decremented. For historical reasons, items are reversed when performing the prepend operation. To maintain the original order when prepending items, you can either reverse the array before calling Adapter.prepend, or use the Adapter.insert method instead.

 |[insert](https://dhilt.github.io/ngx-ui-scroll/#adapter#insert)|(options: {<br>&nbsp;&nbsp;items:&nbsp;MyItem[],<br>&nbsp;&nbsp;before?:&nbsp;ItemsPredicate,<br>&nbsp;&nbsp;after?:&nbsp;ItemsPredicate,<br>&nbsp;&nbsp;beforeIndex?:&nbsp;number,<br>&nbsp;&nbsp;afterIndex?:&nbsp;number,<br>&nbsp;&nbsp;decrease?:&nbsp;boolean<br>})|Inserts _items_ into the buffer or virtually. Only one of the _before_, _after_, _beforeIndex_ and _afterIndex_ options is allowed. If _before_ or _after_ option is used, the Scroller will try to insert items before or after the item that presents in the buffer and satisfies the predicate condition. If _beforeIndex_ or _afterIndex_ option is used, the Scroller will try to insert items by index. If the index to insert is out of the buffer but still belongs to the known datasource boundaries, then the _items_ will be virtualized. Indexes increase by default. Decreasing strategy can be enabled via _decrease_ option. |
 |[remove](https://dhilt.github.io/ngx-ui-scroll/#adapter#remove)|(options: {<br>&nbsp;&nbsp;predicate?:&nbsp;ItemsPredicate,<br>&nbsp;&nbsp;indexes?:&nbsp;number[],<br>&nbsp;&nbsp;increase?:&nbsp;boolean<br>}) <br><br> type&nbsp;ItemsPredicate&nbsp;=<br>&nbsp;&nbsp;(item: ItemAdapter)&nbsp;=><br>&nbsp;&nbsp;&nbsp;&nbsp;boolean|Removes items form buffer and/or virtually. Predicate is a function to be applied to every item presently in the buffer. Predicate must return a boolean value. If predicate's return value is true, the item will be removed. Alternatively, if _indexes_ array is passed, the items whose indexes match the list will be removed. Only one of the _predicate_ and _indexes_ options is allowed. In case of _indexes_, the deletion is performed also virtually. By default, indexes of the items following the deleted ones are decremented. Instead, if _increase_ is set to _true_, the indexes of the items before the removed ones are incremented. |
 |[replace](https://dhilt.github.io/ngx-ui-scroll/#adapter#replace)|(options: {<br>&nbsp;&nbsp;predicate:&nbsp;ItemsPredicate,<br>&nbsp;&nbsp;items:&nbsp;MyItem[],<br>&nbsp;&nbsp;fixRight?:&nbsp;boolean<br>})|Replaces items that continuously match the _predicate_ with an array of new _items_. Indexes are maintained on the assumption that the left border of the dataset is fixed. To release the left border and fix the right one the _fixRight_ option should be set to _true_. |
