Enum AtomicInputValidation

java.lang.Object

java.lang.Enum<AtomicInputValidation>

net.jini.core.constraint.AtomicInputValidation

All Implemented Interfaces:

Serializable, Comparable<AtomicInputValidation>, InvocationConstraint

public enum AtomicInputValidation
extends Enum<AtomicInputValidation>
implements InvocationConstraint

Represents an invariant constraint on ObjectInput and ObjectOutput, covering data transmitted in band as part of the remote call itself. If an invariant violation on in-band data is detected during a remote call, a InvalidObjectException will be thrown, construction of the Object in question will fail atomically (in the client or in the server, depending on which side detected the violation). Invariant validation is fine grained, which means every Object in the graph must have its invariants satisfied, prior to java.lang.Object's constructor being called. This ensures that an object instance cannot be created if invariants are not satisfied.

Java's standard ObjectOutputStream and ObjectInputStream check invariants after construction, circular links and finalizers allow an attacker to obtain references to partially constructed objects before invariants have been checked.

Serialization for this class is guaranteed to produce instances that are comparable with ==.

Method Detail

values

public static AtomicInputValidation[] 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 (AtomicInputValidation c : AtomicInputValidation.values())
    System.out.println(c);

Returns:

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

valueOf

public static AtomicInputValidation 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
