KeyGroupRangeOffsets

public KeyGroupRangeOffsets(KeyGroupRange keyGroupRange,
                            long[] offsets)

Creates key-group range with offsets from the given key-group range. The order of given offsets must be aligned with respect to the key-groups in the range.

参数:

keyGroupRange - The range of key-groups.

offsets - The aligned array of offsets for the given key-groups.

KeyGroupRangeOffsets

public KeyGroupRangeOffsets(int rangeStart,
                            int rangeEnd,
                            long[] offsets)

Creates key-group range with offsets from the given start key-group to end key-group. The order of given offsets must be aligned with respect to the key-groups in the range.

参数:

rangeStart - Start key-group of the range (inclusive)

rangeEnd - End key-group of the range (inclusive)

offsets - The aligned array of offsets for the given key-groups.

KeyGroupRangeOffsets

public KeyGroupRangeOffsets(int rangeStart,
                            int rangeEnd)

Creates key-group range with offsets from the given start key-group to end key-group. All offsets are initially zero.

参数:

rangeStart - Start key-group of the range (inclusive)

rangeEnd - End key-group of the range (inclusive)

KeyGroupRangeOffsets

public KeyGroupRangeOffsets(KeyGroupRange keyGroupRange)

Creates key-group range with offsets for the given key-group range, where all offsets are initially zero.

参数:

keyGroupRange - The range of key-groups.

方法详细资料

newIllegalKeyGroupException

public static IllegalArgumentException newIllegalKeyGroupException(int keyGroup,
                                                                   KeyGroupRange keyGroupRange)

getKeyGroupOffset

public long getKeyGroupOffset(int keyGroup)

Returns the offset for the given key-group. The key-group must be contained in the range.

参数:

keyGroup - Key-group for which we query the offset. Key-group must be contained in the range.

返回:

The offset for the given key-group which must be contained in the range.

setKeyGroupOffset

public void setKeyGroupOffset(int keyGroup,
                              long offset)

Sets the offset for the given key-group. The key-group must be contained in the range.

参数:

keyGroup - Key-group for which we set the offset. Must be contained in the range.

offset - Offset for the key-group.

getIntersection

public KeyGroupRangeOffsets getIntersection(KeyGroupRange keyGroupRange)

Returns a key-group range with offsets which is the intersection of the internal key-group range with the given key-group range.

参数:

keyGroupRange - Key-group range to intersect with the internal key-group range.

返回:

The key-group range with offsets for the intersection of the internal key-group range with the given key-group range.

getKeyGroupRange

public KeyGroupRange getKeyGroupRange()
