Message creation and editing

New messages creation is simply a matter of popping up a dialog and selecting the desired syntax and message. On initialization, all mandatory fields are created and the complete message structure is displayed in a tree format.

Each field can then be selected and its desired value set. The value entry mechanism will change depending on the ASN.1 type selected.

The field's name, type, ASN.1 type and value are displayed. The maximum and minimum limits are also displayed. 

For deeply nested messages a display of the fields parents are also shown to ease navigation through the message.

A find function is available to quickly select desired fields within the message. Fields with unconfigured values can also be found in this way.

Encode and decode

OneViewer encodes the message when it is saved to a file. The message can be saved in either binary or ASCII format. The file format used is simple and can easily be read by other applications. More detailed information is available on request.

A message is decoded when the user opens a file. If a decode error occurs an appropriate error message is displayed.

OneViewer supports the BER, DER, CER, PER (aligned and unaligned), XER, and CXER encoding rules.

Powerful automatic multiple message generation

OneViewer's powerful multiple message generator features make the creation of multiple message simple. Multiple messages can be generated where each message contains a different field value.

Flexible support is available to control the naming of the many message files created.

This function, coupled with the multiple field generator capablity, makes the generation of messages for testing decoders very quick and simple.
