Class AbstractAttributeParser

java.lang.Object

org.opendaylight.protocol.bgp.parser.spi.AbstractAttributeParser

All Implemented Interfaces:

AttributeParser

public abstract class AbstractAttributeParser
extends Object
implements AttributeParser

Abstract base class for AttributeParsers which are aware of RevisedErrorHandling. Inheriting from this class requires that parseAttribute(ByteBuf, AttributesBuilder, RevisedErrorHandling, PeerSpecificParserConstraint) is provided and the simplified parseAttribute(ByteBuf, AttributesBuilder, PeerSpecificParserConstraint) is implemented by this class.

Description copied from interface: AttributeParser

Parses attribute from ByteBuf buffer.

Specified by:

parseAttribute in interface AttributeParser

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.

constraint - Peer specific constraints, may be null

Throws:

org.opendaylight.protocol.bgp.parser.BGPDocumentedException - when an irrecoverable error occurred which has a BGPError assigned

org.opendaylight.protocol.bgp.parser.BGPParsingException - when a general unspecified parsing error occurs.

                                    org.opendaylight.protocol.bgp.parser.BGPTreatAsWithdrawException

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

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:

org.opendaylight.protocol.bgp.parser.BGPDocumentedException - when an irrecoverable error occurred which has a BGPError assigned

org.opendaylight.protocol.bgp.parser.BGPParsingException - when a general unspecified parsing error occurs.

org.opendaylight.protocol.bgp.parser.BGPTreatAsWithdrawException - when parsing according to revised error handling indicates the message should be treated as withdraw.
