Method Detail

affinityKey

public org.gridgain.grid.GridUuid affinityKey()

Returns:

Affinity key for this range.

startOffset

public long startOffset()

Returns:

Range start offset.

endOffset

public long endOffset()

Returns:

Range end offset.

belongs

public boolean belongs(long blockStartOff)

Parameters:

blockStartOff - Block start offset to check.

Returns:

True if block with given start offset belongs to this range.

less

public boolean less(long blockStartOff)

Parameters:

blockStartOff - Block start offset to check.

Returns:

True if block with given start offset is located before this range.

greater

public boolean greater(long blockStartOff)

Parameters:

blockStartOff - Block start offset to check.

Returns:

True if block with given start offset is located after this range.

empty

public boolean empty()

Returns:
