RawBytesComparator

public RawBytesComparator()

Method Detail

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.

Overrides:

getLegacyKeyComparatorName in class KeyValue.KVComparator

Returns:

legacy class name for FileFileTrailer#comparatorClassName

compareFlatKey

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

Deprecated. Since 0.99.2.

Description copied from class: 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.

Overrides:

compareFlatKey in class KeyValue.KVComparator

Returns:

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

compare

public int compare(Cell left,
                   Cell right)

Description copied from class: KeyValue.KVComparator

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

Specified by:

compare in interface Comparator<Cell>

Overrides:

compare in class KeyValue.KVComparator

compareOnlyKeyPortion

public int compareOnlyKeyPortion(Cell left,
                                 Cell right)

Overrides:

compareOnlyKeyPortion in class KeyValue.KVComparator

calcIndexKey

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

Overrides:

calcIndexKey in class KeyValue.KVComparator
