Method Detail

initialize

public void initialize()

Description copied from interface: IXholon

Initialize the tree node. Typically this is only used to re-initialize a node, such as when it is reused through the TreeNodeFactoryStatic.

Specified by:

initialize in interface IXholon

Overrides:

initialize in class XholonWithPorts

getVal

public double getVal()

Description copied from interface: IXholon

Get the value of a "double" maintained by this xholon instance. If a class that implements this interface does not maintain such a value, it should return 0.0 This method can be used in place of getVal_double()

Specified by:

getVal in interface IXholon

Overrides:

getVal in class Xholon

setVal

public void setVal(double val)

Description copied from interface: IXholon

Set the value of a "double" maintained by this xholon instance.

Specified by:

setVal in interface IXholon

Overrides:

setVal in class Xholon

incVal

public void incVal(double incAmount)

Description copied from interface: IXholon

Increment an internal double value by a specified amount. This is a convenience method.

Specified by:

incVal in interface IXholon

Overrides:

incVal in class Xholon

decVal

public void decVal(double decAmount)

Description copied from interface: IXholon

Decrement an internal double value by a specified amount. This is a convenience method.

Specified by:

decVal in interface IXholon

Overrides:

decVal in class Xholon

setRoleName

public void setRoleName(java.lang.String roleName)

Description copied from interface: IXholon

Set name of the role played by this Xholon within a specific context.

Specified by:

setRoleName in interface IXholon

Overrides:

setRoleName in class Xholon

getRoleName

public java.lang.String getRoleName()

Description copied from interface: IXholon

Get name of the role played by this Xholon within a specific context.

Specified by:

getRoleName in interface IXholon

Overrides:

getRoleName in class Xholon

act

public void act()

Description copied from interface: IXholon

Do some action during this time step. Typically all nodes in the tree will do their pre-actions (optional), then all will do their actions, and then all will do their post-actions (optional).

Specified by:

act in interface IXholon

Overrides:

act in class Xholon

performDoubleActivity

public double performDoubleActivity(IXholon activity)

Description copied from interface: IXholon

Perform an activity including the entire activity subtree. This is intended to be used in Behavior encoded as an Activity subtree, and in GP and other evolutionary computation such as ECJ integration with Xholon.

Specified by:

performDoubleActivity in interface IXholon

Overrides:

performDoubleActivity in class Xholon

toString

public java.lang.String toString()

Overrides:

toString in class Xholon
