Method Details

ifNotExists

public CheckAndMutate.Builder ifNotExists(byte[] family,
 byte[] qualifier)

Check for lack of column

Parameters:

family - family to check

qualifier - qualifier to check

Returns:

the CheckAndMutate object

ifEquals

public CheckAndMutate.Builder ifEquals(byte[] family,
 byte[] qualifier,
 byte[] value)

Check for equality

Parameters:

family - family to check

qualifier - qualifier to check

value - the expected value

Returns:

the CheckAndMutate object

ifMatches

public CheckAndMutate.Builder ifMatches(byte[] family,
 byte[] qualifier,
 org.apache.hadoop.hbase.CompareOperator compareOp,
 byte[] value)

Check for match

Parameters:

family - family to check

qualifier - qualifier to check

compareOp - comparison operator to use

value - the expected value

Returns:

the CheckAndMutate object

ifMatches

public CheckAndMutate.Builder ifMatches(org.apache.hadoop.hbase.filter.Filter filter)

Check for match

Parameters:

filter - filter to check

Returns:

the CheckAndMutate object

timeRange

public CheckAndMutate.Builder timeRange(org.apache.hadoop.hbase.io.TimeRange timeRange)

Specify a timerange

Parameters:

timeRange - time range to check

Returns:

the CheckAndMutate object

queryMetricsEnabled

public CheckAndMutate.Builder queryMetricsEnabled(boolean queryMetricsEnabled)

Enables the return of QueryMetrics alongside the corresponding result for this query

This is intended for advanced users who need result-granular, server-side metrics

Does not work

Parameters:

queryMetricsEnabled - true to enable collection of per-result query metrics false to disable metrics collection (resulting in null metrics)

build

public CheckAndMutate build(org.apache.hadoop.hbase.client.Put put)

Build the CheckAndMutate object

Parameters:

put - data to put if check succeeds

Returns:

a CheckAndMutate object

build

public CheckAndMutate build(org.apache.hadoop.hbase.client.Delete delete)

Build the CheckAndMutate object

Parameters:

delete - data to delete if check succeeds

Returns:

a CheckAndMutate object

build

public CheckAndMutate build(org.apache.hadoop.hbase.client.Increment increment)

Build the CheckAndMutate object with an Increment to commit if the check succeeds.

Parameters:

increment - data to increment if check succeeds

Returns:

a CheckAndMutate object

build

public CheckAndMutate build(org.apache.hadoop.hbase.client.Append append)

Build the CheckAndMutate object with an Append to commit if the check succeeds.

Parameters:

append - data to append if check succeeds

Returns:

a CheckAndMutate object

build

public CheckAndMutate build(org.apache.hadoop.hbase.client.RowMutations mutations)

Build the CheckAndMutate object with a RowMutations to commit if the check succeeds.

Parameters:

mutations - mutations to perform if check succeeds

Returns:

a CheckAndMutate object
