org.omg.CORBA_2_3.portable
Class InputStream
- Closeable
This class defines a new CDR input stream methods, added since
CORBA 2.3.
This class is abstract; no direct instances can be instantiated.
Also, up till v 1.4 inclusive there are no methods that would
return it, and only one unimplemented interface,
ValueFactory, needs it as a parameter.
However since 1.3 all methods, declared as returning an
org.omg.CORBA.portable.InputStream actually return the instance of this
derived class and the new methods are accessible after the casting
operation.

read_abstract_interface
public Object read_abstract_interface()
Read the abstract interface. An abstract interface can be either
CORBA value type or CORBA object and is returned as an abstract
java.lang.Object.
As specified in OMG specification, this reads a single
boolean and then delegates either to
read_Object() (for false)
or to
read_value() (for true).
- an abstract interface, unmarshaled from the stream.
read_abstract_interface
public Object read_abstract_interface(Class<T> clz)
Read the abstract interface, corresponding to the passed type.
An abstract interface can be either CORBA value type or CORBA
object and is returned as an abstract java.lang.Object.
As specified in OMG specification, this reads a single
boolean and then delegates either to
read_Object(Class) (for false)
or to
read_value(Class) (for true).
clz - a base class for the abstract interface.
- an abstract interface, unmarshaled from the stream
read_value
public Serializable read_value()
Read a value type structure, extracting the repository id
from the input stream itself. The repository id is optional
in the value type record, but it must be present for this
method to succeed. The
OutputStream of this
implementation always stores the repository id.
The casts the streams ORB into a CORBA 2.3 ORB and then
searched for a suitable value factory, where it delegates
the functionality.
If you know the exact class or can create an unitialised instance
of the value type, it is recommended (faster) to use
read_value(Class) or
read_value(Serializable)
instead.
- an value type structure, unmarshaled from the stream
read_value
public Serializable read_value(Serializable unitialised_value)
Read a value type structure content, when the unitialised
instance is passed as a parameter. It is a fastest method to read
a value type.
As the type is known, the repository Id in the input stream is
optional an not required. The codebase, if present, is also ignored.
The passed instance must implement either
CustomMarshal
for the user-defined reading operations or
StreamableValue
for the standard (generated by IDL compiler) reading operations.
unitialised_value - the unitialised value.
- same value, filled in by the stream content.
read_value
public Serializable read_value(Class<T> clz)
Read a value type structure, corresponing to the passed type.
As the type is known, the repository Id in the input stream is
optional an not required. The codebase, if present, is also ignored.
The passed class must implement either
CustomMarshal
for the user-defined reading operations or
StreamableValue
for the standard (generated by IDL compiler) reading operations.
Also, it must have the parameterless constructor to create a new
instance.
clz - a base class for a value type.
- an value type structure, unmarshaled from the stream
read_value
public Serializable read_value(String repository_id)
Read a value type structure, having the given repository id.
The casts the streams ORB into a CORBA 2.3 ORB and then
searched for a suitable value factory, where it delegates
the functionality.
If you know the exact class or can create an unitialised instance
of the value type, it is recommended (faster) to use
read_value(Class) or
read_value(Serializable)
instead.
repository_id - a repository id of the value type.
- an value type structure, unmarshaled from the stream
read_value
public Serializable read_value(BoxedValueHelper helper)
Use the provided boxed value helper to read the value.
helper - a helper for reading the value from the stream.
- an value type structure, unmarshaled from the stream.
