- Method Detail
  - getNextValue
```
Data getNextValue(Object... params)
```
    Returns value from DataFeed. This method is used to compute new data. Flexibility with number of parameters aims to provide freedom in implementation of whole DataFeed.
    
    Parameters:
    
    params - for DataFeed computing
    
    Returns:
    
    computed value
  - getPreviousValue
```
Data getPreviousValue()
```
    Returns last generated value from DataFeed. Important for easy comparison between new and previous values.
    
    Returns:
    
    last generated value
  - setLabel
```
void setLabel(String label)
```
    Sets label for DataFeed
    
    Parameters:
    
    label - the label
  - getLabel
```
String getLabel()
```
    Returns label for DataFeed
    
    Returns:
    
    label
