Method Summary

OFAction	getAction(OFActionType t) Retrieves an OFAction instance corresponding to the specified OFActionType
java.util.List<OFAction>	parseActions(java.nio.ByteBuffer data, int length) Attempts to parse and return all OFActions contained in the given ByteBuffer, beginning at the ByteBuffer's position, and ending at position+length.
java.util.List<OFAction>	parseActions(java.nio.ByteBuffer data, int length, int limit) Attempts to parse and return all OFActions contained in the given ByteBuffer, beginning at the ByteBuffer's position, and ending at position+length.

Method Detail

getAction

OFAction getAction(OFActionType t)

Retrieves an OFAction instance corresponding to the specified OFActionType

Parameters:

t - the type of the OFAction to be retrieved

Returns:

an OFAction instance

parseActions

java.util.List<OFAction> parseActions(java.nio.ByteBuffer data,
                                      int length)

Attempts to parse and return all OFActions contained in the given ByteBuffer, beginning at the ByteBuffer's position, and ending at position+length.

Parameters:

data - the ByteBuffer to parse for OpenFlow actions

length - the number of Bytes to examine for OpenFlow actions

Returns:

parseActions

java.util.List<OFAction> parseActions(java.nio.ByteBuffer data,
                                      int length,
                                      int limit)

Parameters:

data - the ByteBuffer to parse for OpenFlow actions

length - the number of Bytes to examine for OpenFlow actions

limit - the maximum number of messages to return, 0 means no limit
