                          throws InvalidConfigurationException

Description copied from interface: IMutateable

Mutates a CommandGene.

Specified by:

applyMutation in interface IMutateable

Parameters:

index - references the part of a multipart object, normally not relevant

a_percentage - the mutation rate (0.0 to 1.0)

Returns:

the mutant

Throws:

InvalidConfigurationException

public java.lang.Object clone()

Clones the object. Simple and straight forward implementation here.

Specified by:

clone in interface ICloneable

Overrides:

clone in class java.lang.Object

Returns:

cloned instance of this object

toString

public java.lang.String toString()

toString in class CommandGene

Returns:

the string representation of the command. Especially usefull to output a resulting formula in human-readable form.

getName

public java.lang.String getName()

Overrides:

getName in class CommandGene

Returns:

textual name of this command
