• FuzzyRowFilter

  public FuzzyRowFilter(List<Pair<byte[],byte[]>> fuzzyKeysData)

Method Detail

• filterKeyValue

  public Filter.ReturnCode filterKeyValue(Cell c)

  Description copied from class: Filter
  A way to filter based on the column family, column qualifier and/or the column value. Return code is described below. This allows filters to filter only certain number of columns, then terminate without matching ever column. If filterRowKey returns true, filterKeyValue needs to be consistent with it. filterKeyValue can assume that filterRowKey has already been called for the row. If your filter returns ReturnCode.NEXT_ROW, it should return ReturnCode.NEXT_ROW until Filter.reset() is called just in case the caller calls for the next row. Concrete implementers can signal a failure condition in their code by throwing an IOException.

  Specified by:

  filterKeyValue in class Filter

  Parameters:

  c - the Cell in question

  Returns:

  code as described below

  Filter.ReturnCode

• getNextCellHint

  public Cell getNextCellHint(Cell currentCell)

  Description copied from class: FilterBase
  Filters that are not sure which key must be next seeked to, can inherit this implementation that, by default, returns a null Cell. If the filter returns the match code SEEK_NEXT_USING_HINT, then it should also tell which is the next key it must seek to. After receiving the match code SEEK_NEXT_USING_HINT, the QueryMatcher would call this function to find out which key it must next seek to. Concrete implementers can signal a failure condition in their code by throwing an IOException.

  Overrides:

  getNextCellHint in class FilterBase

  Returns:

  KeyValue which must be next seeked. return null if the filter is not sure which key to seek to next.

• filterAllRemaining

  public boolean filterAllRemaining()

  Description copied from class: FilterBase
  Filters that never filter all remaining can inherit this implementation that never stops the filter early. If this returns true, the scan will terminate. Concrete implementers can signal a failure condition in their code by throwing an IOException.

  Overrides:

  filterAllRemaining in class FilterBase

  Returns:

  true to end scan, false to continue.

• toByteArray

  public byte[] toByteArray()

  Description copied from class: FilterBase
  Return length 0 byte array for Filters that don't require special serialization

  Overrides:

  toByteArray in class FilterBase

  Returns:

  The filter serialized using pb

• parseFrom

  public static FuzzyRowFilter parseFrom(byte[] pbBytes)
                                  throws DeserializationException

  Parameters:

  pbBytes - A pb serialized FuzzyRowFilter instance

  Returns:

  An instance of FuzzyRowFilter made from bytes

  Throws:

  DeserializationException

  toByteArray()

• toString

  public String toString()

  Description copied from class: FilterBase
  Return filter's info for debugging and logging purpose.

  Overrides:

  toString in class FilterBase

• equals

  public boolean equals(Object obj)

  Overrides:

  equals in class Object

• hashCode

  public int hashCode()

  Overrides:

  hashCode in class Object
