Method Details

getDoubleSectionProperty

public double getDoubleSectionProperty(int id)
                                throws NetException

Description copied from class: NodeSection

Gets a double type property of this node. Note that the first 256 identifiers are reserved by NodeSection class.

Overrides:

getDoubleSectionProperty in class Server

Parameters:

id - Property identifier (see properties constants).

Returns:

Property value.

Throws:

NetException - if the requested property is not available.

getDoubleSectionProperty

public double getDoubleSectionProperty(int id,
 JobClass jobClass)
                                throws NetException

Description copied from class: NodeSection

Gets a double type property of this node depending on a specified job class. Note that the first 256 identifiers are reserved by NodeSection class.

Overrides:

getDoubleSectionProperty in class Server

Parameters:

id - Property identifier (see properties constants).

jobClass - jobClass.

Returns:

Property value.

Throws:

NetException - if the requested property is not available.

nodeLinked

protected void nodeLinked(NetNode node)
                   throws NetException

Description copied from class: NodeSection

This method should be overridden to implement a specific behaviour of the node section when the node section itself is linked to the owner node. This method should be used to set node section properties depending on the owner node ones.

Overrides:

nodeLinked in class Server

Parameters:

node - Owner node.

Throws:

NetException

process

protected int process(NetMessage message)
               throws NetException

Description copied from class: NodeSection

This method should be overridden to implement a specific NetMessage processor.

Overrides:

process in class Server

Parameters:

message - message to be processed.

Returns:

message processing result.

Throws:

NetException

setQuantumSize

public void setQuantumSize(double quantumSize)

setSwitchTime

public void setSwitchTime(double switchTime)
