Method Detail

setHandle

public void setHandle(int h)

getHandle

public int getHandle()

setActivated

public void setActivated(boolean v)

A flow must be activated before its packets can be scheduled by the scheduler as QoS_DATA packets. A flow is installed by either a Link.NEW_FLOW or a Link.MODIFY_FLOW event during the installation, the flowspec may have already been stored in the link, the additional flow activation is to avoid packets' being scheduled during installation which may cause the scheduler to fail.
