Method Detail
-
makeForSingleDimension
public static <T> StringPartitionChunk<T> makeForSingleDimension(String start, String end, int chunkNumber, T obj)
-
make
public static <T> StringPartitionChunk<T> make(StringTuple start, StringTuple 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 interfacePartitionChunk<T>
- 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 interfacePartitionChunk<T>
- 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 interfacePartitionChunk<T>
- 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 interfacePartitionChunk<T>
- 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 interfacePartitionChunk<T>
- Returns:
- the sequential numerical id of this partition chunk
-
compareTo
public int compareTo(PartitionChunk<T> chunk)
- Specified by:
compareTo
in interfaceComparable<T>
