Overrides:

read_value in class org.omg.CORBA_2_3.portable.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 org.omg.CORBA_2_3.portable.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 org.omg.CORBA_2_3.portable.InputStream

read_value

public java.io.Serializable read_value(org.omg.CORBA.portable.BoxedValueHelper factory)

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

Overrides:

read_value in class org.omg.CORBA_2_3.portable.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 org.omg.CORBA_2_3.portable.InputStream

read_abstract_interface

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

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 org.omg.CORBA_2_3.portable.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.

updateMutatorConnection

public void updateMutatorConnection(GIOPConnection connection)

updateMutatorConnection is an accessor that updates the ior mutator. By making callers pass in a GIOPConnection not a transport this allows callers to not have to call getTransport which would require a synchronized lock. Therefore if the mutator has not been enabled this is effectively a NOP.

Parameters:

connection - an org.omg.ETF.Connection value
