Enum Constant Summary

Enum Constants

Enum Constant	Description
Idempotent	Operations that use the Slice idempotent keyword can modify object state, but invoking an operation twice in a row must result in the same object state as invoking it once.
Nonmutating	Operations that use the Slice nonmutating keyword must not modify object state.
Normal	Ordinary operations have Normal mode.

Enum Constant Details

Normal

public static final OperationMode Normal

Ordinary operations have Normal mode. These operations modify object state; invoking such an operation twice in a row has different semantics than invoking it once. The Ice run time guarantees that it will not violate at-most-once semantics for Normal operations.

Nonmutating

public static final OperationMode Nonmutating

Operations that use the Slice nonmutating keyword must not modify object state. For C++, nonmutating operations generate const member functions in the skeleton. In addition, the Ice run time will attempt to transparently recover from certain run-time errors by re-issuing a failed request and propagate the failure to the application only if the second attempt fails.

Nonmutating is deprecated; Use the idempotent keyword instead. For C++, to retain the mapping of nonmutating operations to C++ const member functions, use the ["cpp:const"] metadata directive.

Idempotent

public static final OperationMode Idempotent

Operations that use the Slice idempotent keyword can modify object state, but invoking an operation twice in a row must result in the same object state as invoking it once. For example, x = 1 is an idempotent statement, whereas x += 1 is not. For idempotent operations, the Ice run-time uses the same retry behavior as for nonmutating operations in case of a potentially recoverable error.

Method Details

values

public static OperationMode[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static OperationMode valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name

NullPointerException - if the argument is null

value

public int value()

valueOf

public static OperationMode valueOf(int v)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

v - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null
