parseAttribute

public void parseAttribute(io.netty.buffer.ByteBuf buffer,
                           AttributesBuilder builder,
                           RevisedErrorHandling errorHandling,
                           PeerSpecificParserConstraint constraint)
                    throws BGPParsingException

Description copied from interface: AttributeParser

Parses attribute from ByteBuf buffer with the specified RevisedErrorHandling. Default implementation ignores error handling and defers to AttributeParser.parseAttribute(ByteBuf, AttributesBuilder, PeerSpecificParserConstraint).

Specified by:

parseAttribute in interface AttributeParser

Specified by:

parseAttribute in class AbstractAttributeParser

Parameters:

buffer - Encoded attribute body in ByteBuf.

builder - Path attributes builder. Guaranteed to contain all valid attributes whose type is numerically lower than this attribute's type.

errorHandling - RFC7606 error handling type

constraint - Peer specific constraints, may be null

Throws:

BGPParsingException - when a general unspecified parsing error occurs.

serializeAttribute

public void serializeAttribute(Attributes attribute,
                               io.netty.buffer.ByteBuf byteAggregator)

Serialize linkstate attributes.

Specified by:

serializeAttribute in interface AttributeSerializer

Parameters:

attribute - DataObject representing LinkstatePathAttribute

byteAggregator - ByteBuf where all serialized data are aggregated
