This module creates methods when it is used by another module.
There are three types of methods: read_only, read_write,
Attributes specified as read_only get an accessor that only returns
the value of the attribute. Presumably, these attributes are set via
more complicated methods in the class or as a side effect of one of
Attributes specified as read_write will take a single optional
parameter. If given, this parameter will become the new value of the
attribute. This value is then returned from the method. If no
parameter is given, then the current value is returned.
If you want the accessor to use Params::Validate to validate any
values passed to the accessor (and you _do_), then the the accessor
specification should be an array reference containing two elements.
The first element is the accessor name and the second is the
The read_write_contained parameter is used to create accessor for
delayed contained objects. A delayed contained object is one that
is <B>notB> created in the containing objects accessor, but rather at
some point after the containing object is constructed. For example,
the Interpreter object creates Request objects after the Interpreter
itself has been created.
The value of the read_write_contained parameter should be a hash
reference. The keys are the internal name of the contained object,
such as request or compiler. The values for the keys are the same
as the parameters given for read_write accessors.
