- Method Detail
  - getKey
```
K getKey()
```
    Return the key of the element.
    
    Returns:
    
    the key of the element
  - getValue
```
V getValue()
```
    Return the value of the element.

```
void setValue(V value)
```
    Set the value of the element.
    
    Parameters:
    
    value - the new value
  - decreaseKey
```
void decreaseKey(K newKey)
```
    Decrease the key of the element.
    
    Parameters:
    
    newKey - the new key
    
    Throws:
    
    IllegalArgumentException - if the new key is larger than the old key according to the comparator used when constructing the heap or the natural ordering of the elements if no comparator was used
