Development

This section describes how a user can utilize the Application Program Interface (API) of the product-tools package to develop their own tool. The following topics can be found in this section:

API Entry Points

We have not had a chance to document the entry points into the API as of the current release. The best source for this information currently is to view the VTool.java file from the vtool project's source package. Another source of documentation would be the JavaDocs documentation for this project.

ODL Grammar

The parsing of PDS labels has been accomplished using the ANTLR software package. The links below detail the grammar for both the parser a nd the lexer, which were generated from the src/resources/grammar/odl.g source file. If viewing this document in PDF form, see the appendix for the actual grammar.
