MutationType (FoundationDB Java Client API)

java.lang.Object
- java.lang.Enum<MutationType>
- - com.foundationdb.MutationType

All Implemented Interfaces:

Serializable, Comparable<MutationType>
```
public enum MutationType
extends Enum<MutationType>
```
A set of operations that can be performed atomically on a database. These are used as parameters to Transaction.mutate(MutationType, byte[], byte[]).

- Enum Constant Detail
  - ADD
```
public static final MutationType ADD
```
    Performs an addition of little-endian integers. If the existing value in the database is not present or shorter than param, it is first extended to the length of param with zero bytes. If param is shorter than the existing value in the database, the existing value is truncated to match the length of param. The integers to be added must be stored in a little-endian representation. They can be signed in two's complement representation or unsigned. You can add to an integer at a known offset in the value by prepending the appropriate number of zero bytes to param and padding with zero bytes to match the length of the value. However, this offset technique requires that you know the addition will not cause the integer field within the value to overflow.
  - AND
```
@Deprecated
public static final MutationType AND
```
    Deprecated.
    
    Deprecated.
  - BIT_AND
```
public static final MutationType BIT_AND
```
    Performs a bitwise and operation. If the existing value in the database is not present or shorter than param, it is first extended to the length of param with zero bytes. If param is shorter than the existing value in the database, the existing value is truncated to match the length of param.
  - OR
```
@Deprecated
public static final MutationType OR
```
    Deprecated.
    
    Deprecated.
  - BIT_OR
```
public static final MutationType BIT_OR
```
    Performs a bitwise or operation. If the existing value in the database is not present or shorter than param, it is first extended to the length of param with zero bytes. If param is shorter than the existing value in the database, the existing value is truncated to match the length of param.
  - XOR
```
@Deprecated
public static final MutationType XOR
```
    Deprecated.
    
    Deprecated.
  - BIT_XOR
```
public static final MutationType BIT_XOR
```
    Performs a bitwise xor operation. If the existing value in the database is not present or shorter than param, it is first extended to the length of param with zero bytes. If param is shorter than the existing value in the database, the existing value is truncated to match the length of param.
  - MAX
```
public static final MutationType MAX
```
    Performs a little-endian comparison of byte strings. If the existing value in the database is not present or shorter than param, it is first extended to the length of param with zero bytes. If param is shorter than the existing value in the database, the existing value is truncated to match the length of param. The larger of the two values is then stored in the database.
  - MIN
```
public static final MutationType MIN
```
    Performs a little-endian comparison of byte strings. If the existing value in the database is not present or shorter than param, it is first extended to the length of param with zero bytes. If param is shorter than the existing value in the database, the existing value is truncated to match the length of param. The smaller of the two values is then stored in the database.

  - values
```
public static MutationType[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
```
for (MutationType c : MutationType.values())
    System.out.println(c);
```
    Returns:
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static MutationType valueOf(String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    
    Parameters:
    name - the name of the enum constant to be returned.
    
    Returns:
    the enum constant with the specified name
    
    Throws:
    
    IllegalArgumentException - if this enum type has no constant with the specified name
    
    NullPointerException - if the argument is null
  - code
```
public int code()
```
    Gets the FoundationDB native-level constant code for a MutationType.
    
    Returns:
    the native code for a FoundationDB MutationType constant.
