Method Summary
Modifier and TypeMethodDescriptiongetRMIRepositoryID
(Class clz) Returns the CORBA RepositoryId for the given Java class.Returns the CodeBase for this ValueHandler.boolean
isCustomMarshaled
(Class clz) Indicates whether the given class performs custom or default marshaling.readValue
(InputStream in, int offset, Class clz, String repositoryID, RunTime sender) Reads a value from the stream using Java semantics.writeReplace
(Serializable value) If the value contains awriteReplace
method then the result is returned.void
writeValue
(OutputStream out, Serializable value) Writes a value to the stream using Java semantics.

Method Details
-
writeValue
Writes a value to the stream using Java semantics.- Parameters:
out
- the stream to write the value to.value
- the value to be written to the stream.
-
readValue
Reads a value from the stream using Java semantics.- Parameters:
in
- the stream to read the value from.offset
- the current position in the input stream.clz
- the type of the value to be read in.repositoryID
- the RepositoryId of the value to be read in.sender
- the sending context runtime codebase.- Returns:
- the value read from the stream.
-
getRMIRepositoryID
Returns the CORBA RepositoryId for the given Java class.- Parameters:
clz
- a Java class.- Returns:
- the CORBA RepositoryId for the class.
-
isCustomMarshaled
Indicates whether the given class performs custom or default marshaling.- Parameters:
clz
- the class to test for custom marshaling.- Returns:
true
if the class performs custom marshaling,false
if it does not.
-
getRunTimeCodeBase
RunTime getRunTimeCodeBase()Returns the CodeBase for this ValueHandler. This is used by the ORB runtime. The server sends the service context containing the IOR for this CodeBase on the first GIOP reply. The client does the same on the first GIOP request.- Returns:
- the SendingContext.CodeBase of this ValueHandler.
-
writeReplace
If the value contains awriteReplace
method then the result is returned. Otherwise, the value itself is returned.- Parameters:
value
- the value to be marshaled.- Returns:
- the true value to marshal on the wire.
