NAME
Net::Packet::Desc - base class for all desc modules
DESCRIPTION
This is the base class for Net::Packet::DescL2, Net::Packet::DescL3 and Net::Packet::DescL4 modules.
It just provides those layers with inheritable attributes and methods.
A descriptor is required when you want to send frames over network.
ATTRIBUTES
- env
-
A reference to a Net::Packet::Env object. By default, initialized to $Net::Packet::Env variable.
- noEnvSet
-
When a new object is created, the Net::Packet global $Env object as its desc attribute set to this newly created Desc object. Setting it to 1 avoids this. Default is 0.
METHODS
- send (scalar)
-
Send the raw data passed as parameter to the env object.
- close
-
Close the descriptor.
- isDescL2
- isDescL3
- isDescL4
-
Returns true if Desc is of specified type, false otherwise.
