Method Detail

qualifier

AsyncTable.CheckAndMutateBuilder qualifier(byte[] qualifier)

Parameters:

qualifier - column qualifier to check.

timeRange

AsyncTable.CheckAndMutateBuilder timeRange(TimeRange timeRange)

Parameters:

timeRange - time range to check.

ifNotExists

AsyncTable.CheckAndMutateBuilder ifNotExists()

Check for lack of column.

ifEquals

default AsyncTable.CheckAndMutateBuilder ifEquals(byte[] value)

Check for equality.

Parameters:

value - the expected value

ifMatches

AsyncTable.CheckAndMutateBuilder ifMatches(CompareOperator compareOp,
                                           byte[] value)

Parameters:

compareOp - comparison operator to use

value - the expected value

thenPut

CompletableFuture<Boolean> thenPut(Put put)

Parameters:

put - data to put if check succeeds

Returns:

true if the new put was executed, false otherwise. The return value will be wrapped by a CompletableFuture.

thenDelete

CompletableFuture<Boolean> thenDelete(Delete delete)

Parameters:

delete - data to delete if check succeeds

Returns:

true if the new delete was executed, false otherwise. The return value will be wrapped by a CompletableFuture.

thenMutate

CompletableFuture<Boolean> thenMutate(RowMutations mutation)

Parameters:

mutation - mutations to perform if check succeeds

Returns:

true if the new mutation was executed, false otherwise. The return value will be wrapped by a CompletableFuture.
