# CBufferedCharacterItemSet

The `CBufferedCharacterItemSet` class represents a collection of buffered character items and associated character clusters. Each item in the collection is a [`CBufferedCharacterItem`](buffered-character-item.md) object.

## Definition

*Namespace:* dynamsoft::dlr

*Assembly:* DynamsoftLabelRecognizer

```cpp
class CBufferedCharacterItemSet
```

## Methods

| Method               | Description |
|----------------------|-------------|
| [`GetItemsCount`](#getitemscount) | Gets the number of items in the buffered item set. |
| [`GetItem`](#getitem) | Gets a pointer to the CBufferedCharacterItem object at the specified index. |
| [`operator[]`](#operator) | Gets a pointer to the CBufferedCharacterItem object at the specified index. |
| [`GetCharacterClustersCount`](#getcharacterclusterscount) | Gets the number of character clusters in the buffered item set.|
| [`GetCharacterCluster`](#getcharactercluster) | Gets the character cluster at the specified index.|
| [`Retain`](#retain) | Increases the reference count of the CBufferedCharacterItemSet object. |
| [`Release`](#release) | Decreases the reference count of the CBufferedCharacterItemSet object. |

### GetItemsCount
