Method Detail

toString

public java.lang.String toString()

Specified by:

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

execute_double

public double execute_double(ProgramChromosome c,
                             int n,
                             java.lang.Object[] args)

Description copied from class: CommandGene
