Class Request
An object, containing the information, needed to invoke the method of
the local or remote CORBA object. The Request is used in
Dynamic Invocation Interface (DII) which allows dynamic creation of
requests.
abstract Any | add_in_arg()- Add the named input parameter that passes value to
the method being invoked.
|
abstract Any | add_inout_arg()- Add the input/output parameter that passes value both to and from
the method being invoked.
|
abstract Any | add_named_in_arg(String name)- Add the named input parameter that passes value to
the method being invoked.
|
abstract Any | add_named_inout_arg(String name)- Add the named input/output parameter that passes value both to and from
the method being invoked.
|
abstract Any | add_named_out_arg(String name)- Add the named output parameter that passes value from
the method being invoked.
|
abstract Any | add_out_arg()- Add the output parameter that passes value from
the method being invoked.
|
abstract NVList | arguments()- Return the list of all previously added parameters.
|
abstract ContextList | contexts()- Get the context list object for this request.
|
abstract Context | ctx()- Get the context, previously set using
ctx(Context).
|
abstract void | ctx(Context a_context)- Set the context that shuld be later returned by
ctx().
|
abstract Environment | env()- Returns the container, eclosing an exception that the invoked method
has thrown.
|
abstract ExceptionList | exceptions()- List the exceptions that may be thrown by the CORBA object method being
invoked.
|
abstract void | get_response()- Allow to access the response that has been previously sent using
send_deferred().
|
abstract void | invoke()- Submit the request, suspending the current thread until the
answer is received.
|
abstract String | operation()- Get the name of the method being invoked.
|
abstract boolean | poll_response()- Check if the response is received to the request that was
previously send using
send_deferred().
|
abstract NamedValue | result()- Get the value, returned by the method, together with its name.
|
abstract Any | return_value()- Get the value, returned by the method.
|
abstract void | send_deferred()- Send a request without suspending the current thread.

add_in_arg
public abstract Any add_in_arg()
Add the named input parameter that passes value to
the method being invoked. This is similar to the "passing by value"
conception.
The created parameter is returned allowing to set the value.
add_inout_arg
public abstract Any add_inout_arg()
Add the input/output parameter that passes value both to and from
the method being invoked. This is similar to the "passing by reference"
conception.
The created parameter is returned allowing to set the value.
add_named_in_arg
public abstract Any add_named_in_arg(String name)
Add the named input parameter that passes value to
the method being invoked. This is similar to the "passing by value"
conception.
The created parameter is returned allowing to set the value.
name - the parameter name.
add_named_inout_arg
public abstract Any add_named_inout_arg(String name)
Add the named input/output parameter that passes value both to and from
the method being invoked. This is similar to the "passing by reference"
conception.
The created parameter is returned allowing to set the value.
name - the parameter name.
add_named_out_arg
public abstract Any add_named_out_arg(String name)
Add the named output parameter that passes value from
the method being invoked. Differently from the java
language, the CORBA IDL method can return multiple values.
The created parameter is returned allowing to set the value.
name - the parameter name.
add_out_arg
public abstract Any add_out_arg()
Add the output parameter that passes value from
the method being invoked. Differently from the java
language, the CORBA IDL method can return multiple values.
The created parameter is returned allowing to set the value.
arguments
public abstract NVList arguments()
Return the list of all previously added parameters.
contexts
public abstract ContextList contexts()
Get the context list object for this request.
- a list of strings that must be resolved and sent with the
invocation.
ctx
public abstract Context ctx()
Get the context, previously set using
ctx(Context).
The context contains the details about this request.
ctx
public abstract void ctx(Context a_context)
Set the context that shuld be later returned by
ctx().
This context contains the details about this request.
a_context - a context to set.
env
public abstract Environment env()
Returns the container, eclosing an exception that the invoked method
has thrown.
- the Environment object, containng the exception.
exceptions
public abstract ExceptionList exceptions()
List the exceptions that may be thrown by the CORBA object method being
invoked.
invoke
public abstract void invoke()
Submit the request, suspending the current thread until the
answer is received.
operation
public abstract String operation()
Get the name of the method being invoked.
- the name of the method being invoked.
poll_response
public abstract boolean poll_response()
Check if the response is received to the request that was
previously send using
send_deferred().
- true if the response has been already received, false otherwise.
result
public abstract NamedValue result()
Get the value, returned by the method, together with its name.
- the value, returned by the method.
return_value
public abstract Any return_value()
Get the value, returned by the method.
- the value, returned by the method.
send_oneway
public abstract void send_oneway()
Send a request and forget about it, not waiting for a response.
This can be done also for methods that normally are expected
to return some values.
set_return_type
public abstract void set_return_type(TypeCode returns)
Set the return type.
returns - the type of the value, returned in response to this
request.
target
public abstract Object target()
Return the CORBA object on that the method would be invoked.
