# IntermediateResultUnit

The `IntermediateResultUnit` class represents an intermediate result unit used in image processing. It is an abstract base class with multiple subclasses, each representing a different type of unit such as pre-detected regions, localized barcodes, decoded barcodes, localized text lines, binary image, gray image, etc.

```java
int getUsageCount()
```

**Return value**

Returns the usage count of the intermediate result.

### clone
