Class AbstractSyncObj<T>

java.lang.Object

com.h3c.sdn.misc.dsync.AbstractSyncObj<T>

Type Parameters:

T - the type of sync object

All Implemented Interfaces:

SyncObj<T>, Serializable

Direct Known Subclasses:

BroadcastTreeSyncObj, DpSuppressedPortsSyncObj, LinkSyncObj, MsgContextSyncObj, NodeMessageSyncObj, TopologyClusterSyncObj

public abstract class AbstractSyncObj<T>
extends Object
implements SyncObj<T>

Default implementation of SyncObj abstraction, which uses Jackson's Smile data format, the "binary json" data interchange. (https://github.com/FasterXML/jackson-dataformat-smile). This offers 30-50% time and space improvements over jackson's default dataformat and thus translates to big saving when used in HA workflows related to ZK/Keystore.

Method Detail

mapper

public static com.fasterxml.jackson.databind.ObjectMapper mapper()

Returns:

the mapper

decode

public abstract SyncObj<T> decode(com.fasterxml.jackson.databind.node.ObjectNode jsonNode)

Convert a given raw ObjectNode to required SyncObject.

Parameters:

jsonNode - the raw ObjectNode synthesized from the bytes retrieved from the HA infrastructure.

Returns:

the decoded SyncObject

unmarshal

public SyncObj<T> unmarshal(byte[] payload)

Synthesizes the object from the given bytes that were retrieved from the transmitted medium.

Specified by:

unmarshal in interface SyncObj<T>

Parameters:

payload - the object in bytes form retrieved from the HA medium.

Returns:

the synthesized object

encode

public abstract com.fasterxml.jackson.databind.node.ObjectNode encode(com.fasterxml.jackson.databind.node.ObjectNode rawNode)

Stuffs an empty ObjectNode with desired form of the SyncObj. at this point.

Parameters:

rawNode - the empty ObjectNode that needs to be built on.

Returns:

the fully dressed ObjectNode that represents the SyncObj.

marshal

public byte[] marshal()

Converts this object into byte format ready for transmission. Construct bytes for sending across the channel(bus) from the object.

Specified by:

marshal in interface SyncObj<T>

Returns:

the object in byte format ready for transmission over the medium.

isNull

public static boolean isNull(Object obj)

Checks if given object is null.

Parameters:

obj - object that needs to be checked

Returns:

true if object is null, false otherwise
