Method Detail

writePathId

public static void writePathId(PathId pathId,
                               io.netty.buffer.ByteBuf buffer)

Writes path-id value into the buffer when the path-id is not null or does not equal to zero.

Parameters:

pathId - The NLRI Path Identifier.

buffer - The ByteBuf where path-id value can be written.

readPathId

public static PathId readPathId(io.netty.buffer.ByteBuf buffer)

Reads Path Identifier (4 bytes) from buffer.

Parameters:

buffer - Input buffer.

Returns:

Decoded PathId.

extractPathId

public static org.opendaylight.yangtools.yang.common.Uint32 extractPathId(org.opendaylight.yangtools.yang.data.api.schema.NormalizedNode<?,?> data,
                                                                          org.opendaylight.yangtools.yang.data.api.YangInstanceIdentifier.NodeIdentifier pathNii)

Extract PathId from route change received.

Parameters:

data - Data containing the path Id

pathNii - Path Id NodeIdentifier specific per each Rib support

Returns:

The path identifier from data change

buildPathId

public static PathId buildPathId(org.opendaylight.yangtools.yang.data.api.schema.DataContainerNode<? extends org.opendaylight.yangtools.yang.data.api.YangInstanceIdentifier.PathArgument> routesCont,
                                 org.opendaylight.yangtools.yang.data.api.YangInstanceIdentifier.NodeIdentifier pathIdNii)

Build Path Id.

Parameters:

routesCont - route container

pathIdNii - path Id node Identifier

Returns:

PathId or null in case is not the container

createNidKey

public static org.opendaylight.yangtools.yang.data.api.YangInstanceIdentifier.NodeIdentifierWithPredicates createNidKey(org.opendaylight.yangtools.yang.common.QName routeQName,
                                                                                                                        org.opendaylight.yangtools.util.ImmutableOffsetMapTemplate<org.opendaylight.yangtools.yang.common.QName> routeKeyTemplate,
                                                                                                                        Object routeKeyValue,
                                                                                                                        Optional<org.opendaylight.yangtools.yang.data.api.schema.DataContainerChild<? extends org.opendaylight.yangtools.yang.data.api.YangInstanceIdentifier.PathArgument,?>> maybePathIdLeaf)

Build Route Key for supporting mp. Key is composed by 2 elements (route-key + path Id).

Parameters:

routeQName - route QName

routeKeyTemplate - route key template

routeKeyValue - route key value

maybePathIdLeaf - path id container, it might me supported or not, in that case default 0 value will be assigned

Returns:

Route Key Nid
