public class Output

```
-
This is a chromosome output. Outputs are a special - type of mutable element with a single connection. It - returns the value of its single connection, but it - may not be connected to - it terminates a chromosome - active connection path. -

- When mutating an output, it is easiest to use mutate(). - Alternatively, you may also perform a specific mutation using - setSource(...).

public Output(Chromosome chromosome,
-              int index)
```
    -
    Makes a new instance of Output with the - specified arguments.
    -
    -
    Parameters:
    -
    chromosome - the chromosome this output belongs to.
    -
    index - the output index.

    calculate
    -
```
public java.lang.Object calculate()
```
    -
    -
    Returns:
    -
    the value of the output's source.
    -
    -
  - - - -
  - -
    getIndex
    -
```
public int getIndex()
```
    -
    -
    Returns:
    -
    this output's index.
    -
    -
  - - - -
  - -
    setSource
    -
```
public void setSource(Connection newConnection)
```
    -
    This method sets the output source to the specified connection.
    -
    -
    Parameters:
    -
    newConnection - the Connection to connect to.
    -
    -
  - - - -
  - -
    getSource
    -
```
public Connection getSource()
```
    -
    -
    Returns:
    -
    the source of this output's value.
    -
    -
  - - - -
  - -
    getActiveNodes
    -
```
public void getActiveNodes(java.util.ArrayList<Node> activeNodes)
```
    -
    Calls getActive(...) on this output's - source. This kicks off a recursive process whereby - all nodes connected to this output are added to the - specified list of nodes. This is used to create a - list of all active nodes.
    -
    -
    Parameters:
    -
    activeNodes - the list to add all active nodes to.
    -
    -

  - -
    copyOf
    -
```
public boolean copyOf(Mutable m)
```
    -
    Description copied from interface: Mutable
    -
    Asserts if the specified element is a copy of the elements - this is called on.
    - This method returns true if and only if: -
    - the elements being compared are not the same instance;
    - the connections of the compared elements are not the same instance;
    - the elements have the same function (in the case of Node);
    - the grid position of the elements themselves are the same;
    - the grid position of all equivalent connections are the same;
    -
    
    - The relationship computed by this method is: -
    - symmetric: a.copyOf(b) == b.copyOf(a);
    - not reflexive: a.copyOf(a) returns false;
    - not transitive: if a.copyOf(b) is true and b.copyOf(c) is true, a.copyOf(c) is - not necessarily true since it is possible that a == c.
    -
    -
    Specified by:
    -
    copyOf in interface Mutable
    -
    Parameters:
    -
    m - the mutable element to compare to.
    -
    Returns:
    -
    true if element is a copy of this element.
    -

    mutate
    -
```
public void mutate()
```
    -
    Description copied from interface: Mutable
    -
    This method performs an arbitrary mutation on the Mutable. -
    
    - In the case of nodes, this chooses to mutate a function or connection - fairly, and carries out the required mutation by using the node's own - reference to chromosome. -
    
    - In the case of outputs, this simply picks a random connection to serve - as the source - any connection is allowed.

    Specified by:
    -

    toString
    -
```
public java.lang.String toString()
```
    -
    -
    Overrides:
    -
    toString in class java.lang.Object
