Package oracle.nosql.driver.ops

## Class DeleteResult

- java.lang.Object
- - oracle.nosql.driver.ops.Result
  - - oracle.nosql.driver.ops.DeleteResult

-     public class DeleteResult
      extends Result

  Represents the result of a `NoSQLHandle.delete(oracle.nosql.driver.ops.DeleteRequest)` operation.

  If the delete succeeded `getSuccess()` returns true. Information about the existing row on failure may be available using `getExistingValue()` and .`getExistingVersion()`, depending on the use of `DeleteRequest.setReturnRow(boolean)`.

  - ### Method Detail

    - #### getSuccess

          public boolean getSuccess()

      Returns true if the delete operation succeeded.
      Returns:
        true if the operation succeeded

    - #### getExistingVersion

          public Version getExistingVersion()

      Returns the existing row `Version` if available. It will be available if the target row exists and the operation failed because of a `Version` mismatch and the corresponding `DeleteRequest` the method `DeleteRequest.setReturnRow(boolean)` was called with a true value.
      Returns:
        the Version

    - #### getExistingValue

          public MapValue getExistingValue()

      Returns the existing row value if available. It will be available if the target row exists and the operation failed because of a `Version` mismatch and the corresponding `DeleteRequest` the method `DeleteRequest.setReturnRow(boolean)` was called with a true value.
      Returns:
        the value

    - #### getReadKB

          public int getReadKB()

      Returns the read throughput consumed by this operation, in KBytes. This is the actual amount of data read by the operation. The number of read units consumed is returned by `getReadUnits()` which may be a larger number because this was an update operation.
      Returns:
        the read KBytes consumed

    - #### getWriteKB

          public int getWriteKB()

      Returns the write throughput consumed by this operation, in KBytes.
      Returns:
        the write KBytes consumed

    - #### getReadUnits

          public int getReadUnits()

      Returns the read throughput consumed by this operation, in read units. This number may be larger than that returned by `getReadKB()` because it was an update operation.
      Returns:
        the read units consumed

    - #### getWriteUnits

          public int getWriteUnits()

      Returns the write throughput consumed by this operation, in write units.
      Returns:
        the write units consumed

    - #### toString

          public String toString()

      Overrides:
        `toString` in class `Object`
