Math::Symbolic::Custom::Base - Base class for tree tests and transformations # Extending the Math::Symbolic::Custom class: package Math::Symbolic::Custom::MyTransformations; use Math::Symbolic::Custom::Base; BEGIN {*import = \&Math::Symbolic::Custom::Base::aggregate_import} our $Aggregate_Export = [qw/apply_transformation1 .../]; sub apply_transformation1 { # ... } This is a base class for your extensions to the Math::Symbolic::Custom class. To extend the class, just use the following template for your custom class: package Math::Symbolic::Custom::MyTransformations; use Math::Symbolic::Custom::Base; BEGIN {*import = \&Math::Symbolic::Custom::Base::aggregate_import} our $Aggregate_Export = [...]; # exported subroutines listed here. # Now implement the subroutines. # Exported subroutine names must start with 'apply_', 'mod_', # 'is_', 'test_', 'contains_', or 'to_' # ... 1;

EXPORT
Uses a custom exporter implementation to export certain routines from the invoking namespace to the Math::Symbolic::Custom namespace. But... Nevermind.

aggregate_import
aggregate_import() is the only public subroutine defined by Math::Symbolic::Custom::Base and should only be called in BEGIN blocks like the one shown in the SYNOPSIS above.
