6 Math::Symbolic::Custom::Base - Base class for tree tests and
7 transformations
8
10 # Extending the Math::Symbolic::Custom class:
11 package Math::Symbolic::Custom::MyTransformations;
12 use Math::Symbolic::Custom::Base;
13 BEGIN {*import = \&Math::Symbolic::Custom::Base::aggregate_import}
14
15 our $Aggregate_Export = [qw/apply_transformation1 .../];
16 sub apply_transformation1 {
17 # ...
18 }
19
21 This is a base class for your extensions to the Math::Symbolic::Custom
22 class.
23
24 To extend the class, just use the following template for your custom
25 class:
26
27 package Math::Symbolic::Custom::MyTransformations;
28
29 use Math::Symbolic::Custom::Base;
30 BEGIN {*import = \&Math::Symbolic::Custom::Base::aggregate_import}
31
32 our $Aggregate_Export = [...]; # exported subroutines listed here.
33
34 # Now implement the subroutines.
35 # Exported subroutine names must start with 'apply_', 'mod_',
36 # 'is_', 'test_', 'contains_', or 'to_'
37
38 # ...
39
40 1;
41
42 EXPORT
43 Uses a custom exporter implementation to export certain routines from
44 the invoking namespace to the Math::Symbolic::Custom namespace. But...
45 Nevermind.
46
48 aggregate_import
49 aggregate_import() is the only public subroutine defined by
50 Math::Symbolic::Custom::Base and should only be called in BEGIN blocks
51 like the one shown in the SYNOPSIS above.
