类 KeyValue.RawBytesComparator

java.lang.Object

org.apache.hadoop.hbase.KeyValue.KVComparator

org.apache.hadoop.hbase.KeyValue.RawBytesComparator

所有已实现的接口:

Comparator<Cell>, KeyValue.SamePrefixComparator<byte[]>, org.apache.hadoop.io.RawComparator<Cell>

封闭类:

KeyValue

public static class KeyValue.RawBytesComparator
extends KeyValue.KVComparator

This is a TEST only Comparator used in TestSeekTo and TestReseekTo.

构造器详细资料

KeyValue.RawBytesComparator

public KeyValue.RawBytesComparator()

方法详细资料

getLegacyKeyComparatorName

public String getLegacyKeyComparatorName()

The HFileV2 file format's trailer contains this class name. We reinterpret this and instantiate the appropriate comparator. TODO: With V3 consider removing this.

覆盖:

getLegacyKeyComparatorName 在类中 KeyValue.KVComparator

返回:

legacy class name for FileFileTrailer#comparatorClassName

compareFlatKey

@Deprecated
public int compareFlatKey(byte[] left,
                            int loffset,
                            int llength,
                            byte[] right,
                            int roffset,
                            int rlength)

已过时。 Since 0.99.2.

从类复制的说明: KeyValue.KVComparator

Compares left to right assuming that left,loffset,llength and right,roffset,rlength are full KVs laid out in a flat byte[]s.

覆盖:

compareFlatKey 在类中 KeyValue.KVComparator

返回:

0 if equal, <0 if left smaller, >0 if right smaller

compare

public int compare(Cell left,
          Cell right)

从类复制的说明: KeyValue.KVComparator

Compares the Key of a cell -- with fields being more significant in this order: rowkey, colfam/qual, timestamp, type, mvcc

指定者:

compare 在接口中 Comparator<Cell>

覆盖:

compare 在类中 KeyValue.KVComparator

compareOnlyKeyPortion

public int compareOnlyKeyPortion(Cell left,
                        Cell right)

覆盖:

compareOnlyKeyPortion 在类中 KeyValue.KVComparator

calcIndexKey

public byte[] calcIndexKey(byte[] lastKeyOfPreviousBlock,
                  byte[] firstKeyInBlock)

覆盖:

calcIndexKey 在类中 KeyValue.KVComparator
