description::
|
||
|
|
for event patterns see link::Classes/Psym::. Overview: link::Overviews/JITLib::.

ClassMethods::
|
||
|
|
|
||
|
|
method::new
|
||
|
|
|
||
|
|
argument::pattern
|
||
|
|
a pattern that returns symbols or characters. Arrays are converted to parallel patterns ( link::Classes/Ptuple:: ).
|
||
|
|
|
||
|
|
argument::dict
|
||
|
|
the dictionary to be used for lookup. By default, this is code::Pdefn.all::, so one can embed Pdefns by name.
|
||
|
|
|
||
|
|
InstanceMethods::
|
||
|
|
|
||
|
|
method::dict
|
||
|
|
set the dictionary to be used.
