Class Output

java.lang.Object

jcgp.backend.population.Output

All Implemented Interfaces:

MutableElement

public class Output
extends java.lang.Object
implements MutableElement

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.

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.

Constructor Detail

Output

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.

Method Detail

calculate

public java.lang.Object calculate()

Returns:

the value of the output's source.

getIndex

public int getIndex()

getSource

public Connection getSource()

getActiveNodes

public void getActiveNodes(java.util.ArrayList<Node> activeNodes)

setConnection

public void setConnection(int index,
                          Connection newConnection)

When mutating an output, the index parameter is simply ignored and the output source is set.

Specified by:

setConnection in interface MutableElement

Parameters:

index - the connection index to set.

newConnection - the chromosome element to connect to.

MutableElement.setConnection(int, jcgp.backend.population.Connection)

copyOf

public boolean copyOf(MutableElement m)

Description copied from interface: MutableElement

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 MutableElement

Parameters:

m - the mutable element to compare to.

Returns:

true if element is a copy of this element.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
