read_value

public java.io.Serializable read_value()

Overrides:

read_value in class InputStream

read_value

public java.io.Serializable read_value(java.lang.String rep_id)

Overrides read_value(java.io.Serializable value) in org.omg.CORBA_2_3.portable.InputStream

Overrides:

read_value in class InputStream

read_value

public java.io.Serializable read_value(java.io.Serializable value)

Unmarshals a valuetype instance from this stream. The value returned is the same value passed in, with all the data unmarshaled (IDL-to-Java Mapping 1.2, August 2002, 1.13.1, p. 1-39). The specified value is an uninitialized value that is added to the ORB's indirection table before unmarshaling (1.21.4.1, p. 1-117). This method is intended to be called from custom valuetype factories. Unlike the other read_value() methods in this class, this method does not expect a GIOP value tag nor a repository id in the stream. Overrides read_value(value) in org.omg.CORBA_2_3.portable.InputStream

Overrides:

read_value in class InputStream

read_value

public java.io.Serializable read_value(java.lang.Class clz)

Overrides read_value(clz) in org.omg.CORBA_2_3.portable.InputStream

Overrides:

read_value in class InputStream

read_value

public java.io.Serializable read_value(BoxedValueHelper factory)

Overrides read_value(factory) in org.omg.CORBA_2_3.portable.InputStream

Overrides:

read_value in class InputStream

read_abstract_interface

public java.lang.Object read_abstract_interface()

Reads an abstract interface from this stream. The abstract interface Reads an abstract interface from this stream. The abstract interface appears as a union with a boolean discriminator, which is true if the union contains a CORBA object reference, or false if the union contains a value.

Overrides:

read_abstract_interface in class InputStream

read_abstract_interface

public java.lang.Object read_abstract_interface(java.lang.Class clz)

Reads an abstract interface from this stream. The abstract interface appears as a union with a boolean discriminator, which is true if the union contains a CORBA object reference, or false if the union contains a value.

Overrides:

read_abstract_interface in class InputStream

get_pos

public int get_pos()

register_value

public void register_value(java.io.Serializable value)

Stores `value' into this stream's valueMap. This is provided as a callback for value factories, so that a value factory can store an object into the map before actually reading its state. This is essential for unmarshalling recursive values.
