Method Summary

OFActionFactory	getActionFactory() Retrieves an OFActionFactory
OFInstruction	getInstruction(OFInstructionType t) Retrieves an OFInstruction instance corresponding to the specified OFInstructionType
java.util.List<OFInstruction>	parseInstructions(java.nio.ByteBuffer data, int length) Attempts to parse and return all OFInstruction contained in the given ByteBuffer, beginning at the ByteBuffer's position, and ending at position+length.
java.util.List<OFInstruction>	parseInstructions(java.nio.ByteBuffer data, int length, int limit) Attempts to parse and return all OFInstruction contained in the given ByteBuffer, beginning at the ByteBuffer's position, and ending at position+length.

Method Detail

getInstruction

OFInstruction getInstruction(OFInstructionType t)

Retrieves an OFInstruction instance corresponding to the specified OFInstructionType

Parameters:

t - the type of the OFInstruction to be retrieved

Returns:

an OFInstruction instance

parseInstructions

java.util.List<OFInstruction> parseInstructions(java.nio.ByteBuffer data,
                                                int length)

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

Parameters:

data - the ByteBuffer to parse for OpenFlow instructions

length - the number of Bytes to examine for OpenFlow instructions

Returns:

a list of OFInstruction instances

parseInstructions

java.util.List<OFInstruction> parseInstructions(java.nio.ByteBuffer data,
                                                int length,
                                                int limit)

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

Parameters:

data - the ByteBuffer to parse for OpenFlow instructions

length - the number of Bytes to examine for OpenFlow instructions

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

Returns:

a list of OFInstruction instances

getActionFactory

OFActionFactory getActionFactory()

Retrieves an OFActionFactory

Returns:

an OFActionFactory
