Network Library: Eiffel Remote Object Server (EROS)

This library has 37 classes.

ECF: eros.ecf

Source code: directory list

EROS (for Eiffel Remote Object Server), is an experimental an XML orientated remote procedure call application framework with an original protocol based purely on XML processing instructions rather that any special XML tags.

Features

Demo Applications

Two demo applications are provided that do signal math including Fourier transformations based on Greg Lee's Numeric Eiffel Library.

  1. signal-math.ecf is a multi-mode command-line application with 2 client modes and 2 server-test modes.
  2. signal-math-server.ecf performs the same calculations as the server mode of demo 1 but is multi-threaded and has a graphical user interface to control the thread logging context visible in terminal console.

Build Notes

When including the eros.ecf in your project it is necessary to define a custom variable eros_server_enabled. To build a server application set the value to true. To build a client application set value to false.

EROS_REMOTE_REQUEST

Format EROS request something like:

<?xml version="1.0" encoding="ISO-8859-1"?>
<?create $generator?>
<vector-complex>
   <row..
</vector-complex>
<?call {MY_CLASS}.my_routine (1, {COLUMN_VECTOR_COMPLEX_64}, 0.1, 2.3e-15,
                                                                         'hello')?>

OR

<?call{MY_CLASS}.my_routine?>

Note: COLUMN_VECTOR_COMPLEX_64 is an example of a place holder for an instance of a class deserialized from XML

EROS_REMOTE_XML_OBJECT_EXCHANGER

Remote xml object exchanger

common/request

EROS_CALL_REQUEST_BUILDABLE_FROM_NODE_SCAN

Routine call request buildable from node scan

EROS_CALL_REQUEST_HANDLER

Object to handle remote procedure call requests for the duration of a session. A session finishes when the procedure set_stopping is called either by the server shutdown process or remotely by the client.

Communication with the client is via either partial binary XML or plaintext XML. This mode is settable in either direction by set_inbound_transmission_type, set_outbound_transmission_type.

EROS_CALL_REQUEST_PARSER

Parse call expression like for example:

{MY_CLASS}.my_routine (1, {COLUMN_VECTOR_COMPLEX_64}, 0.1, 2.3e-15, 'hello')

OR

{MY_CLASS}.my_routine

Note: COLUMN_VECTOR_COMPLEX_64 is an example of a place holder for an instance of a class deserialized from XML
