Constructor Details

PointMapping

public PointMapping(ShardMapManager shardMapManager, PointMappingCreationInfo creationInfo)

Constructs a point mapping given mapping creation arguments.

Parameters:

shardMapManager - Owning ShardMapManager.

creationInfo - Mapping creation information.

PointMapping

public PointMapping(ShardMapManager shardMapManager, ShardMap shardMap, StoreMapping mapping)

Internal constructor used for deserialization from store representation of the mapping object.

Parameters:

shardMapManager - Owning ShardMapManager.

shardMap - Owning shard map.

mapping - Storage representation of the mapping.

Method Details

clone

public PointMapping clone()

Clones the instance.

Returns:

clone of the instance.

equals

public boolean equals(Object obj)

Determines whether the specified object is equal to the current object.

Parameters:

obj - The object to compare with the current object.

Returns:

True if the specified object is equal to the current object; otherwise, false.

getId

Identity of the mapping.

getKey

public ShardKey getKey()

getKind

public MappingKind getKind()

Type of the mapping.

Overrides:

PointMapping.getKind()

getShard

public Shard getShard()

Gets Shard that contains the key value.

getShardInfo

public Shard getShardInfo()

Shard that contains the key value.

getShardMapId

public UUID getShardMapId()

Identify of the ShardMap this shard belongs to.

Overrides:

PointMapping.getShardMapId()

getShardMapManager

public ShardMapManager getShardMapManager()

ShardMapManager for the object.

Overrides:

PointMapping.getShardMapManager()

getStatus

value

toString

public String toString()

Converts the object to its string representation.

Returns:

String representation of the object.

validate

public void validate(StoreShardMap shardMap, Connection conn)

Performs validation that the local representation is as up-to-date as the representation on the backing data store.

Parameters:

shardMap - Shard map to which the shard provider belongs.

conn - Connection used for validation.

validateAsync

public Callable validateAsync(StoreShardMap shardMap, Connection conn)
