Method Detail

extract

public static Serializable extract(Any a)

Extract the value type from the given Any.

Parameters: a the Any to extract from.

Returns: the extracted value type.

id

public static String id()

Return the value base helper repository id.

Returns: IDL:omg.org/CORBA/ValueBase:1.0, always.

insert

public static void insert(Any a, Serializable that)

Insert the value base that is Serializable into the given Any.

Parameters: a the Any to insert into. that the value base to insert.

read

public static Serializable read(InputStream input)

Read the value base from the given input stream.

Parameters: input a stream to read from.

Returns: the loaded value.

Throws: MARSHAL if the reading has failed due any reason.

type

public static TypeCode type()

Get the typecode of the value type.

Returns: the typecode of the value type

write

public static void write(OutputStream output, Serializable value)

Write the value base into the given stream. If the passed value implements the {@link CustomMarshal}, the helper uses {@link CustomMarshal#marshal} to write the content in a user defined way. Otherwise, this implementation initialises the {@link ObjectOutputStream} and writes through it.

Parameters: output a stream to write to. value a value to write.

Throws: MARSHAL if the writing failed due any reason.
