Constructor Detail

IO_data

public IO_data(Object data,
               long byteSize,
               int destID)

Allocates a new IO_data object

Parameters:

data - the data object

byteSize - the size of a data (in bytes)

destID - the destination ID

Pre Condition:

data != null, byteSize >= 0, destID >= 0

Post Condition:

$none

IO_data

public IO_data(Object data,
               long byteSize,
               int destID,
               int netServiceLevel)

Allocates a new IO_data object with a specific network service level.

The network service level of 0 is the normal or default level. Other levels are treated according to the policy being followed by the system. For example, if using SCFQScheduler as a packet scheduler, then setting the level to 1 or higher means this object gets a higher priority.

Parameters:

data - the data object

byteSize - the size of a data (in bytes)

destID - the destination ID

netServiceLevel - determines the kind of service this packet receives in the network (applicable to selected PacketScheduler class only)
