  - getInstance
```
public static Closure getInstance(Closure[] closures)
```
    Factory method that performs validation and copies the parameter array.
    
    Parameters:
    closures - the closures to chain, copied, no nulls
    
    Returns:
    the chained closure
    
    Throws:
    
    IllegalArgumentException - if the closures array is null
    
    IllegalArgumentException - if any closure in the array is null
  - getInstance
```
public static Closure getInstance(Collection closures)
```
    Create a new Closure that calls each closure in turn, passing the result into the next closure. The ordering is that of the iterator() method on the collection.
    
    Parameters:
    closures - a collection of closures to chain
    
    Returns:
    the chained closure
    
    Throws:

```
public static Closure getInstance(Closure closure1,
                  Closure closure2)
```
    Factory method that performs validation.
    
    Parameters:
    closure1 - the first closure, not null
    closure2 - the second closure, not null
    
    Returns:
    the chained closure
    
    Throws:
    
    IllegalArgumentException - if either closure is null
  - execute
```
public void execute(Object input)
```
    Execute a list of closures.
    
    Specified by:
    
    execute in interface Closure
    
    Parameters:
    input - the input object passed to each closure
  - getClosures
```
public Closure[] getClosures()
```
    Gets the closures, do not modify the array.
