- public class Add
- extends Function
<typeX> Add(<typeX> num1, <typeX> num2)
Add is a generic function that returns the result of adding both arguments.
Add needs to be Type instantiated during construction to work with
particular argument Types. The supported argument Types include BYTE,
SHORT, INT, LONG, FLOAT and DOUBLE.

Add
public Add(Type type)
- Constructs an Add Function that works with the specified Type. The
supported Types include BYTE, SHORT, INT, LONG, FLOAT and DOUBLE.
- Parameters:
- type - The Type of this Add Function.
evaluateByte
public final byte evaluateByte(Individual i,
Gene arguments[]) throws EvaluationException
- Used to Add arguments of BYTE Types.
- Parameters:
- i - The individual being evaluated.
- arguments - The Gene trees representing the arguments to be added.
- Returns:
- A byte representing the sum of the arguments.
- Throws: EvaluationException
- If there is an evaluation failure.
- Overrides:
- evaluateByte in class Function
evaluateShort
public final short evaluateShort(Individual i,
Gene arguments[]) throws EvaluationException
- Used to Add arguments of SHORT Types.
- Parameters:
- i - The individual being evaluated.
- arguments - The Gene trees representing the arguments to be added.
- Returns:
- A short representing the sum of the arguments.
- Throws: EvaluationException
- If there is an evaluation failure.
- Overrides:
- evaluateShort in class Function
evaluateInt
public final int evaluateInt(Individual i,
Gene arguments[]) throws EvaluationException
- Used to Add arguments of INT Types.
- Parameters:
- i - The individual being evaluated.
- arguments - The Gene trees representing the arguments to be added.
- Returns:
- An int representing the sum of the arguments.
- Throws: EvaluationException
- If there is an evaluation failure.
- Overrides:
- evaluateInt in class Function
evaluateLong
public final long evaluateLong(Individual i,
Gene arguments[]) throws EvaluationException
- Used to Add arguments of LONG Types.
- Parameters:
- i - The individual being evaluated.
- arguments - The Gene trees representing the arguments to be added.
- Returns:
- A long representing the sum of the arguments.
- Throws: EvaluationException
- If there is an evaluation failure.
- Overrides:
- evaluateLong in class Function
evaluateFloat
public final float evaluateFloat(Individual i,
Gene arguments[]) throws EvaluationException
- Used to Add arguments of FLOAT Types.
- Parameters:
- i - The individual being evaluated.
- arguments - The Gene trees representing the arguments to be added.
- Returns:
- A float representing the sum of the arguments.
- Throws: EvaluationException
- If there is an evaluation failure.
- Overrides:
- evaluateFloat in class Function
evaluateDouble
public final double evaluateDouble(Individual i,
Gene arguments[]) throws EvaluationException
- Used to Add arguments of DOUBLE Types.
- Parameters:
- i - The individual being evaluated.
- arguments - The Gene trees representing the arguments to be added.
- Returns:
- A double representing the sum of the arguments.
- Throws: EvaluationException
- If there is an evaluation failure.
- Overrides:
- evaluateDouble in class Function
instance
public final Primitive instance()
- Creates an instance of this Add object. The Type instantiation is
preserved so that if an INT Add is being cloned, the clone will also be
INT instantiated.
- Returns:
- A reference to this Object (yes the same object, since
the type information is to be the same, there are therefore
no instance variables to be modified.
- Overrides:
- instance in class Primitive
toString
public String toString()
- Returns a String representation of this Function.
- Returns:
- A String containing the name of the Function.
- Overrides:
- toString in class Primitive
