```
public static To child(java.lang.String childName)
```
    Forward the key/value pair to one of the downstream processors designated by the downstream processor name.
    
    Parameters:
    
    childName - name of downstream processor
    
    Returns:
    
    a new To instance configured with childName
  - all
```
public static To all()
```
    Forward the key/value pair to all downstream processors
    
    Returns:
    
    a new To instance configured for all downstream processor
  - withTimestamp
```
public To withTimestamp(long timestamp)
```
    Set the timestamp of the output record.
    
    Parameters:
    
    timestamp - the output record timestamp
    
    Returns:
    
    itself (i.e., this)
  - equals
```
public boolean equals(java.lang.Object o)
```
    Overrides:
    
    equals in class java.lang.Object
  - hashCode
```
public int hashCode()
```
    Equality is implemented in support of tests, *not* for use in Hash collections, since this class is mutable.
    
    Overrides:
    
    hashCode in class java.lang.Object
