parseAttribute

public void parseAttribute(io.netty.buffer.ByteBuf buffer,
                           AttributesBuilder builder,
                           RevisedErrorHandling errorHandling,

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:

BGPDocumentedException - when an irrecoverable error occurred which has a BGPError assigned

BGPTreatAsWithdrawException - when parsing according to revised error handling indicates the message should be treated as withdraw.

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