Appendix B: Object Constructor Parameters
This appendix provides a quick reference to all the
constructor parameters of the major pieces of the Mason framework. See Chapter 6 or the official Mason documentation for more detail, including information on how and where to specify them.
It's important to understand the relationships among the various pieces of
Mason's framework; Figure B-1 shows how they relate to one another. Keep in mind that you can pass any class's parameters to a class that contains it. For example, you can pass any Compiler parameters to the new()
method of the Interpreter, ApacheHandler, or CGIHandler. In the figure, the
solid arrows indicate a "contains one" relationship, and the dashed
arrows indicate a "contains many" relationship.
