Math::Symbolic::CustomUsertContributedtPerSymbolic::Custom::Pattern::Export(3)

NAME
       Math::Symbolic::Custom::Pattern::Export - Export	method to MS::Custom

SYNOPSIS
	 use Math::Symbolic::Custom::Pattern;

	 # later:
	 my $pattern = $tree->to_pattern();
	 # and even later:
	 $another_tree->is_of_form($pattern);

DESCRIPTION
       This module is an extension to the Math::Symbolic module. A basic
       familiarity with	that module is required.

       Please have a look at the Math::Symbolic::Custom::Pattern module	first.
       This is an internal module only.	It manages to add two new methods to
       all Math::Symbolic objects: "is_of_form"	and "to_pattern". It uses the
       Math::Symbolic::Custom mechanism	for that.

   EXPORT
       In a way, this module exports the "is_of_form" and "to_pattern" methods
       to Math::Symbolic::Base.	Please look at Math::Symbolic::Custom.

   Math::Symbolic method is_of_form
       This method can be called on any	Math::Symbolic tree. First argument
       must be a pattern. Returns true if the pattern matches the tree and
       false if	not.  As with the "match()" method on
       Math::Symbolic::Custom::Pattern objects,	the true value returned
       reflects	the way	the pattern matched. Please see
       Math::Symbolic::Custom::Pattern for details.

       The pattern may either be a Math::Symbolic::Custom::Pattern object
       (fastest) or a Math::Symbolic tree representing a pattern (decent
       speed, since only the pattern object needs to be	constructed) or	a
       string to be parsed as a	Math::Symbolic tree (very slow since the
       string has to be	parsed).

       For details on patterns,	please refer to	the documentation of
       Math::Symbolic::Custom::Pattern.

       This method always throws fatal errors since returning a	boolean	is
       used for	valid, non-error return	values.	Therefore, if you plan to pass
       unvalidated objects or strings to be parsed, consider wrapping calls to
       this method in "eval {}"	blocks.	(Note that "eval BLOCK"	is the safer
       brother of the much despised "eval STRING". See perlfunc.)

   Math::Symbolic method to_pattern
       Generates a Math::Symbolic::Custom::Pattern object from the
       Math::Symbolic tree "to_pattern"	is called on. The pattern can be used
       with the	"is_of_form()" method or like any other
       Math::Symbolic::Custom::Pattern object. (See that package for details
       on patterns.)
