Method Detail

writeExternal

public void writeExternal(java.io.ObjectOutput out)
                   throws java.io.IOException

Specified by:

writeExternal in interface java.io.Externalizable

Throws:

java.io.IOException

readExternal

public void readExternal(java.io.ObjectInput in)
                  throws java.io.IOException,
                         java.lang.ClassNotFoundException

Specified by:

readExternal in interface java.io.Externalizable

Throws:

java.io.IOException

java.lang.ClassNotFoundException

writeExternal

public abstract void writeExternal(EObjectOutputStream out,
                 T obj)
                            throws java.io.IOException

The class implements the writeExternal method to save an object by calling the methods of DataOutput for its primitive values or calling the writeObject method of ObjectOutput for objects, strings, and arrays. This method can get context by methods of EObjectOutputStream like getDatabase and getIdManager.

Parameters:

out - the EObjectOutputStream stream to write the object to

obj - object to save

Throws:

java.io.IOException - Includes any I/O exceptions that may occur

readExternal

public abstract T readExternal(EObjectInputStream in)
                        throws java.io.IOException,
                               java.lang.ClassNotFoundException

The oclass implements the readExternal method to restore an object by calling the methods of DataInput for primitive types and readObject for objects, strings and arrays. The readExternal method must read the values in the same sequence and with the same types as were written by writeExternal. This method can get context by methods of EObjectOutputStream like getDatabase and getIdManager.

Parameters:

in - the stream to read data from in order to restore the object

Returns:

restored object

Throws:

java.io.IOException - if I/O errors occur

java.lang.ClassNotFoundException - If the class for an object being restored cannot be found.
