@InterfaceAudience.Public

public class SingleColumnValueExcludeFilter
extends SingleColumnValueFilter

A Filter that checks a single column value, but does not emit the tested column. This will enable a performance boost over SingleColumnValueFilter, if the tested column value is not actually needed as input (besides for the filtering itself).

构造器详细资料

SingleColumnValueExcludeFilter

public SingleColumnValueExcludeFilter(byte[] family,
                              byte[] qualifier,
                              CompareFilter.CompareOp compareOp,
                              byte[] value)

Constructor for binary compare of the value of a single column. If the column is found and the condition passes, all columns of the row will be emitted; except for the tested column value. If the column is not found or the condition fails, the row will not be emitted.

参数:

family - name of column family

qualifier - name of column qualifier

compareOp - operator

value - value to compare column values against

SingleColumnValueExcludeFilter

public SingleColumnValueExcludeFilter(byte[] family,
                              byte[] qualifier,
                              CompareFilter.CompareOp compareOp,
                              ByteArrayComparable comparator)

Constructor for binary compare of the value of a single column. If the column is found and the condition passes, all columns of the row will be emitted; except for the tested column value. If the condition fails, the row will not be emitted.

Use the filterIfColumnMissing flag to set whether the rest of the columns in a row will be emitted if the specified column to check is not found in the row.

参数:

family - name of column family

qualifier - name of column qualifier

compareOp - operator

comparator - Comparator to use.

SingleColumnValueExcludeFilter

protected SingleColumnValueExcludeFilter(byte[] family,
                              byte[] qualifier,
                              CompareFilter.CompareOp compareOp,
                              ByteArrayComparable comparator,
                              boolean filterIfMissing,
                              boolean latestVersionOnly)

Constructor for protobuf deserialization only.

方法详细资料

hasFilterRow

public boolean hasFilterRow()

从类复制的说明: FilterBase

Fitlers that never filter by modifying the returned List of Cells can inherit this implementation that does nothing. Primarily used to check for conflicts with scans(such as scans that do not read a full row at a time).

覆盖:

hasFilterRow 在类中 SingleColumnValueFilter

返回:

True if this filter actively uses filterRowCells(List) or filterRow().

filterRowCells

public void filterRowCells(List<Cell> kvs)

从类复制的说明: FilterBase

Filters that never filter by modifying the returned List of Cells can inherit this implementation that does nothing. Chance to alter the list of Cells to be submitted. Modifications to the list will carry on Concrete implementers can signal a failure condition in their code by throwing an IOException.

覆盖:

filterRowCells 在类中 FilterBase

参数:

kvs - the list of Cells to be filtered

createFilterFromArguments

public static Filter createFilterFromArguments(ArrayList<byte[]> filterArguments)

toByteArray

public byte[] toByteArray()

从类复制的说明: FilterBase

Return length 0 byte array for Filters that don't require special serialization

覆盖:

toByteArray 在类中 SingleColumnValueFilter

返回:

The filter serialized using pb

parseFrom

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

参数:

pbBytes - A pb serialized SingleColumnValueExcludeFilter instance

返回:

An instance of SingleColumnValueExcludeFilter made from bytes

抛出:

DeserializationException

另请参阅:

toByteArray()

equals

public boolean equals(Object obj)

覆盖:

equals 在类中 SingleColumnValueFilter

hashCode

public int hashCode()

覆盖:

hashCode 在类中 SingleColumnValueFilter
