Interface ValueHandler
public
interface
ValueHandler
Serializes Java objects to and from CDR (GIOP) streams. The working instance
of the value handler is returned by
Util and can
be altered by setting the system property "javax.rmi.CORBA.ValueHandlerClass"
to the name of the alternative class that must implement ValueHandler.
Method Summary |
String | getRMIRepositoryID(Class clz)
Get CORBA repository Id for the given java class.
|
RunTime | getRunTimeCodeBase()
Returns the CodeBase for this ValueHandler.
|
boolean | isCustomMarshaled(Class clz)
Indicates that the given class is responsible itself for writing its
content to the stream. |
Serializable | readValue(InputStream in, int offset, Class clz, String repositoryID, RunTime sender)
Read value from the CORBA input stream in the case when the value is not
Streamable or CustomMarshall'ed. |
Serializable | writeReplace(Serializable value)
When the value provides the writeReplace method, the result of this method
is written. |
void | writeValue(OutputStream out, Serializable value)
Write value to CORBA output stream using java senmatics.

public String getRMIRepositoryID(Class clz)
Get CORBA repository Id for the given java class.
The syntax of the repository ID is the initial ?RMI:?, followed by the Java
class name, followed by name, followed by a hash code string, followed
optionally by a serialization version UID string.
For Java identifiers that contain illegal OMG IDL identifier characters
such as ?$?, any such illegal characters are replaced by ?\U? followed by
the 4 hexadecimal characters (in upper case) representing the Unicode
value.
Parameters: clz a class for that the repository Id is required.
Returns: the class repository id.
public RunTime getRunTimeCodeBase()
Returns the CodeBase for this ValueHandler.
Returns: the codebase.
public boolean isCustomMarshaled(Class clz)
Indicates that the given class is responsible itself for writing its
content to the stream. Such classes implement either Streamable
(default marshalling, generated by IDL-to-java compiler) or
CustomMarshal (the user-programmed marshalling).
Parameters: clz the class being checked.
Returns: true if the class supports custom or default marshalling, false
otherwise.
public Serializable readValue(InputStream in, int offset, Class clz, String repositoryID, RunTime sender)
Read value from the CORBA input stream in the case when the value is not
Streamable or CustomMarshall'ed. The fields of the class being written will
be accessed using reflection.
Parameters: in a CORBA stream to read. offset the current position in the input stream. clz the type of value being read. repositoryID the repository Id of the value being read. sender the sending context that should provide data about the
message originator.
Returns: the object, extracted from the stream.
public Serializable writeReplace(Serializable value)
When the value provides the writeReplace method, the result of this method
is written. Otherwise, the value itself is written.
Parameters: value the value that should be written to the stream.
Returns: the value that will be actually written to the stream.
public void writeValue(OutputStream out, Serializable value)
Write value to CORBA output stream using java senmatics.
Parameters: out a stream to write into. value a java object to write.
