Field Detail

v

Value v

The variable's value.

---

name

java.lang.String name

The variable's name.

---

reg

int reg

Constructor Detail

Variable

public Variable(double p,
                java.lang.String n)

Class constructor, sets the value (from a double) and name for this variable.

---

Variable

public Variable(Value p,
                java.lang.String n)

Class constructor, sets the value (from an value object) and name for this variable.

Variable

public Variable()

Method Detail

getClone

public ExpressionTree getClone()

Description copied from class: ExpressionTree

Convenience method to retrieve a clone of expressionTree as type expressionTree.

Overrides:

getClone in class ExpressionTree

---

toString

public java.lang.String toString()

Returns the variable's name as a String.

Overrides:

toString in class ExpressionTree

---

setVariable

public void setVariable(double p)

Sets the variables value from a double.

---

getNumParams

public int getNumParams()

Returns the number of parameters this node expects.

Overrides:

getNumParams in class ExpressionTree

---

getParams

public ExpressionTree[] getParams()

Returns the parameters this node is holding.

Overrides:

getParams in class ExpressionTree

---

setParams

public void setParams(ExpressionTree[] dummy)

Description copied from class: ExpressionTree

Set this node's parameters. Note: Currently does not check that p[] has the correct number of elements. If p[] has too many elements, the extras are simply thrown out. If, however, there are too few, the results are unpredicatable. This behavior should be modified in future versions to be more robust.

Overrides:

setParams in class ExpressionTree

---

getMachine

public org.maloi.evolvo.expressiontree.vm.Machine getMachine()

Builds a simple stack machine to evaluate this expression. Simply creates a new machine and passes it on to the buildMachine(machine) method.

Overrides:

getMachine in class ExpressionTree

---

buildMachine

public void buildMachine(org.maloi.evolvo.expressiontree.vm.Machine myMachine)

Overrides:

buildMachine in class ExpressionTree

---

setName

private void setName(java.lang.String n)

---
