public interface AttributeParser

Common interface for attribute parser implementation.

Method Summary

Modifier and Type	Method and Description
void	parseAttribute(io.netty.buffer.ByteBuf buffer, AttributesBuilder builder) Parses attribute from ByteBuf buffer.
default void	parseAttribute(io.netty.buffer.ByteBuf buffer, AttributesBuilder builder, PeerSpecificParserConstraint constraint) Invokes parseAttribute(ByteBuf, AttributesBuilder), so the constraint is omitted.

Method Detail

parseAttribute

void parseAttribute(@Nonnull
                    io.netty.buffer.ByteBuf buffer,
                    @Nonnull
                    AttributesBuilder builder)
             throws BGPDocumentedException,
                    BGPParsingException

Parses attribute from ByteBuf buffer.

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.

Throws:

BGPDocumentedException

BGPParsingException

parseAttribute

default void parseAttribute(@Nonnull
                            io.netty.buffer.ByteBuf buffer,
                            @Nonnull
                            AttributesBuilder builder,
                            @Nullable

                     throws BGPDocumentedException,
                            BGPParsingException

Invokes parseAttribute(ByteBuf, AttributesBuilder), so the constraint is omitted. Override for specific parser behavior.

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.

Throws:

BGPDocumentedException

BGPParsingException
