Class MemberBox

java.lang.Object

org.mozilla.javascript.MemberBox

All Implemented Interfaces:

Serializable

final class MemberBox
extends Object
implements Serializable

Wrapper class for Method and Constructor instances to cache getParameterTypes() results, recover from IllegalAccessException in some cases and provide serialization support.

readObject

private void readObject(ObjectInputStream in)
                 throws IOException,
ClassNotFoundException

Throws:

IOException

ClassNotFoundException

writeObject

private void writeObject(ObjectOutputStream out)
                  throws IOException

Throws:

IOException

writeMember

private static void writeMember(ObjectOutputStream out,
 Member member)
                         throws IOException

Writes a Constructor or Method object.

Methods and Constructors are not serializable, so we must serialize information about the class, the name, and the parameters and recreate upon deserialization.

Throws:

IOException

readMember

private static Member readMember(ObjectInputStream in)
                          throws IOException,
ClassNotFoundException

Reads a Method or a Constructor from the stream.

Throws:

IOException

ClassNotFoundException

writeParameters

private static void writeParameters(ObjectOutputStream out,
 Class<?>[] parms)
                             throws IOException

Writes an array of parameter types to the stream.

Requires special handling because primitive types cannot be found upon deserialization by the default Java implementation.

Throws:

IOException

readParameters

private static Class<?>[] readParameters(ObjectInputStream in)
                                  throws IOException,
ClassNotFoundException

Reads an array of parameter types from the stream.

Throws:

IOException

ClassNotFoundException
