Constructor Detail

IntegerPartitionChunk

public IntegerPartitionChunk(Integer start,
                             Integer end,
                             int chunkNumber,
                             T object)

Method Detail

make

public static <T extends Overshadowable> IntegerPartitionChunk<T> make(Integer start,
                                                                       Integer end,
                                                                       int chunkNumber,
                                                                       T obj)

getObject

public T getObject()

Description copied from interface: PartitionChunk

Returns the payload, generally an object that can be used to perform some action against the shard.

Specified by:

getObject in interface PartitionChunk<T extends Overshadowable>

Returns:

the payload

abuts

public boolean abuts(PartitionChunk<T> chunk)

Description copied from interface: PartitionChunk

Determines if this PartitionChunk abuts another PartitionChunk. A sequence of abutting PartitionChunks should start with an object where isStart() == true and eventually end with an object where isEnd() == true.

Specified by:

abuts in interface PartitionChunk<T extends Overshadowable>

Parameters:

chunk - input chunk

Returns:

true if this chunk abuts the input chunk

isStart

public boolean isStart()

Description copied from interface: PartitionChunk

Returns true if this chunk is the beginning of the partition. Most commonly, that means it represents the range [-infinity, X) for some concrete X.

Specified by:

isStart in interface PartitionChunk<T extends Overshadowable>

Returns:

true if the chunk is the beginning of the partition

isEnd

public boolean isEnd()

Description copied from interface: PartitionChunk

Returns true if this chunk is the end of the partition. Most commonly, that means it represents the range [X, infinity] for some concrete X.

Specified by:

isEnd in interface PartitionChunk<T extends Overshadowable>

Returns:

true if the chunk is the end of the partition

getChunkNumber

public int getChunkNumber()

Description copied from interface: PartitionChunk

Returns the partition chunk number of this PartitionChunk. I.e. if there are 4 partitions in total and this is the 3rd partition, it will return 2

Specified by:

getChunkNumber in interface PartitionChunk<T extends Overshadowable>

Returns:

the sequential numerical id of this partition chunk

compareTo

public int compareTo(PartitionChunk<T> chunk)

Specified by:

compareTo in interface Comparable<T extends Overshadowable>

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object
