Class MarshalledWrapper

java.lang.Object
com.sun.jini.proxy.MarshalledWrapper
All Implemented Interfaces:
Serializable
public class MarshalledWrapper extends Object implements Serializable
Wrapper around MarshalledInstance that samples the integrity setting (if any) of the stream it is unmarshalled from, and uses that setting to determine whether or not to verify codebase integrity when calling the get method of the contained MarshalledInstance.

    Description
    MarshalledWrapper(Object obj)
    Creates a new MarshalledWrapper wrapping a MarshalledInstance containing the given object.

  • Method Summary

    Modifier and Type
    Method
    Description
    boolean
    equals(Object obj)
    Compares the specified object with this MarshalledWrapper for equality.
    Object
    get()
    Returns the result of calling the get method of the wrapped MarshalledInstance, passing the integrity value sampled during deserialization as the verifyCodebaseIntegrity argument.
    boolean
    getIntegrity()
    Returns the integrity value sampled during deserialization of this MarshalledWrapper instance, or false if this instance was not produced by deserialization or was deserialized from a stream with no integrity protection setting.
    int
    hashCode()
    Returns the hash code value for this MarshalledWrapper.
    static boolean
    integrityEnforced(ObjectInputStream stream)
    Returns the integrity protection setting of the given stream, determined as follows: if the stream implements ObjectStreamContext and has in its context collection an object of type IntegrityEnforcement, the integrityEnforced method of that object is called and the resulting value returned; otherwise, false is returned.

  • Constructor Details

    • MarshalledWrapper

      public MarshalledWrapper(Object obj) throws IOException
      Creates a new MarshalledWrapper wrapping a MarshalledInstance containing the given object.
      Parameters:
      obj - object to create MarshalledInstance with
      Throws:
      IOException - if MarshalledInstance creation fails

  • Method Details

    • integrityEnforced

      public static boolean integrityEnforced(ObjectInputStream stream)
      Returns the integrity protection setting of the given stream, determined as follows: if the stream implements ObjectStreamContext and has in its context collection an object of type IntegrityEnforcement, the integrityEnforced method of that object is called and the resulting value returned; otherwise, false is returned.
      Returns:
      integrity protection setting of the given stream

    • get

      public Object get() throws IOException, ClassNotFoundException
      Returns the result of calling the get method of the wrapped MarshalledInstance, passing the integrity value sampled during deserialization as the verifyCodebaseIntegrity argument. If this MarshalledWrapper instance was not produced by deserialization or was deserialized from a stream with no integrity protection setting, then a verifyCodebaseIntegrity value of false is used.
      Returns:
      the object unmarshalled by the wrapped MarshalledInstance
      Throws:
      IOException - if an IOException occurs during unmarshalling
      ClassNotFoundException - if any classes necessary for reconstructing the object being unmarshalled cannot be found

    • getIntegrity

      public boolean getIntegrity()
      Returns the integrity value sampled during deserialization of this MarshalledWrapper instance, or false if this instance was not produced by deserialization or was deserialized from a stream with no integrity protection setting.
      Returns:
      sampled integrity value

    • hashCode

      public int hashCode()
      Returns the hash code value for this MarshalledWrapper.
      Overrides:
      hashCode in class Object
      Returns:
      the hash code value for this MarshalledWrapper.

    • equals

      public boolean equals(Object obj)
      Compares the specified object with this MarshalledWrapper for equality. This method returns true if and only if the specified object is of the same class as this object and its wrapped MarshalledInstance is equal to the one in this object.
      Overrides:
      equals in class Object
      Parameters:
      obj - object to compare with
      Returns:
      true if obj is equivalent to this object; false otherwise
