Methods Summary
public abstract Any	add_in_arg() Creates an input argument and adds it to this Request object. return an Any object that contains the value and typecode for the input argument added
public abstract Any	add_inout_arg() Adds an input/output argument to this Request object. return an Any object that contains the value and typecode for the input/output argument added
public abstract Any	add_named_in_arg(java.lang.String name) Creates an input argument with the given name and adds it to this Request object. param name the name of the argument being added return an Any object that contains the value and typecode for the input argument added
public abstract Any	add_named_inout_arg(java.lang.String name) Adds an input/output argument with the given name to this Request object. param name the name of the argument being added return an Any object that contains the value and typecode for the input/output argument added
public abstract Any	add_named_out_arg(java.lang.String name) Adds an output argument with the given name to this Request object. param name the name of the argument being added return an Any object that contains the value and typecode for the output argument added
public abstract Any	add_out_arg() Adds an output argument to this Request object. return an Any object that contains the value and typecode for the output argument added
public abstract NVList	arguments() Retrieves the NVList object containing the arguments to the method being invoked. The elements in the list are NamedValue objects, with each one describing an argument to the method. return the NVList object containing the arguments for the method
public abstract ContextList	contexts() Retrieves the ContextList object for this request. This list contains context Strings that need to be resolved and sent with the invocation. return the list of context strings whose values need to be resolved and sent with the invocation.
public abstract Context	ctx() Retrieves the Context object for this request. This is a list of properties giving information about the client, the environment, or the circumstances of this request. return the Context object that is to be used to resolve any context strings whose values need to be sent with the invocation
public abstract void	ctx(Context c) Sets this request's Context object to the one given. param c the new Context object to be used for resolving context strings
public abstract Environment	env() Retrieves the Environment object for this request. It contains the exception that the method being invoked has thrown (after the invocation returns). return the Environment object for this request
public abstract ExceptionList	exceptions() Retrieves the ExceptionList object for this request. This list contains TypeCode objects describing the exceptions that may be thrown by the method being invoked. return the ExceptionList object describing the exceptions that may be thrown by the method being invoked
public abstract void	get_response() Allows the user to access the response for the invocation triggered earlier with the send_deferred method. exception WrongTransaction if the method get_response was invoked from a different transaction's scope than the one from which the request was originally sent. See the OMG Transaction Service specification for details.
public abstract void	invoke() Makes a synchronous invocation using the information in the Request object. Exception information is placed into the Request object's environment object.
public abstract java.lang.String	operation() Retrieves the name of the method to be invoked. return the name of the method to be invoked
public abstract boolean	poll_response() Allows the user to determine whether a response has been received for the invocation triggered earlier with the send_deferred method. return true if the method response has been received; false otherwise
public abstract NamedValue	result() Retrieves the NamedValue object containing the return value for the method. return the NamedValue object containing the result of the method
public abstract Any	return_value() Returns the Any object that contains the value for the result of the method. return an Any object containing the value and typecode for the return value
public abstract void	send_deferred() Makes an asynchronous invocation on the request. In other words, it does not wait for a response before it returns to the user. The user can then later use the methods poll_response and get_response to get the result or exception information for the invocation.
public abstract void	send_oneway() Makes a oneway invocation on the request. In other words, it does not expect or wait for a response. Note that this can be used even if the operation was not declared as oneway in the IDL declaration. No response or exception information is returned.
public abstract void	set_return_type(TypeCode tc) Sets the typecode for the return value of the method. param tc the TypeCode object containing type information for the return value
public abstract org.omg.CORBA.Object	target() Retrieves the the target object reference. return the object reference that points to the object implementation for the method to be invoked
