Method Detail

getMaximumStreamFormatVersion

public byte getMaximumStreamFormatVersion()

Description copied from interface: ValueHandlerMultiFormat

Returns the maximum stream format version for RMI/IDL custom value types that is supported by this ValueHandler object. The ValueHandler object must support the returned stream format version and all lower versions. An ORB may use this value to include in a standard IOR tagged component or service context to indicate to other ORBs the maximum RMI-IIOP stream format that it supports. If not included, the default for GIOP 1.2 is stream format version 1, and stream format version 2 for GIOP 1.3 and higher.

Specified by:

getMaximumStreamFormatVersion in interface ValueHandlerMultiFormat

writeValue

public void writeValue(OutputStream out,
              Serializable value,
              byte streamFormatVersion)

Description copied from interface: ValueHandlerMultiFormat

Allows the ORB to pass the stream format version for RMI/IDL custom value types. If the ORB calls this method, it must pass a stream format version between 1 and the value returned by the getMaximumStreamFormatVersion method inclusive, or else a BAD_PARAM exception with standard minor code will be thrown. If the ORB calls the older ValueHandler.writeValue(OutputStream, Serializable) method, stream format version 1 is implied. The ORB output stream passed to the ValueHandlerMultiFormat.writeValue method must implement the ValueOutputStream interface, and the ORB input stream passed to the ValueHandler.readValue method must implement the ValueInputStream interface.

Specified by:

writeValue in interface ValueHandlerMultiFormat

writeValue

public void writeValue(OutputStream out,
              Serializable value)

Writes the value to the stream using java semantics.

Specified by:

writeValue in interface ValueHandler

Parameters:

out - The stream to write the value to

value - The value to be written to the stream

readValue

public Serializable readValue(InputStream _in,
                     int offset,
                     Class<?> clazz,
                     String repositoryID,
                     RunTime _sender)

Reads a value from the stream using java semantics.

Specified by:

readValue in interface ValueHandler

Parameters:

_in - The stream to read the value from

clazz - The type of the value to be read in

_sender - The sending context runtime

offset - the current position in the input stream.

repositoryID - the RepositoryId of the value to be read in.

Returns:

the value read from the stream.

getRMIRepositoryID

public String getRMIRepositoryID(Class<?> clz)

Returns the repository ID for the given RMI value Class.

Specified by:

getRMIRepositoryID in interface ValueHandler

Parameters:

clz - The class to return a repository ID for.

Returns:

the repository ID of the Class.

isCustomMarshaled

public boolean isCustomMarshaled(Class<?> clz)

Indicates whether the given Class performs custom or default marshaling.

Specified by:

isCustomMarshaled in interface ValueHandler

Parameters:

clz - The class to test for custom marshaling.

Returns:

True if the class performs custom marshaling, false if it does not.

getRunTimeCodeBase

public 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 clients do the same on the first GIOP request.

Specified by:

getRunTimeCodeBase in interface ValueHandler

Returns:

the SendingContext.CodeBase of this ValueHandler.

useFullValueDescription

public boolean useFullValueDescription(Class<?> clazz,
                              String repositoryID)
                                throws IOException

Returns a boolean of whether or not RepositoryId indicates FullValueDescriptor. used for backward compatability

Throws:

IOException

getClassName

public String getClassName(String id)

getClassFromType

public Class<?> getClassFromType(String id)
                          throws ClassNotFoundException

Throws:

ClassNotFoundException

getAnyClassFromType

public Class<?> getAnyClassFromType(String id)
                             throws ClassNotFoundException

Throws:

ClassNotFoundException

createForAnyType

public String createForAnyType(Class<?> cl)

getDefinedInId

public String getDefinedInId(String id)

getUnqualifiedName

public String getUnqualifiedName(String id)

getSerialVersionUID

public String getSerialVersionUID(String id)

isAbstractBase

public boolean isAbstractBase(Class<?> clazz)

isSequence

public boolean isSequence(String id)

writeReplace

public Serializable writeReplace(Serializable value)

If the value contains a writeReplace method then the result is returned. Otherwise, the value itself is returned.

Specified by:

writeReplace in interface ValueHandler

Parameters:

value - the value to be marshaled.

Returns:

the true value to marshal on the wire.
