NAME
       PPI::Dumper - Dumping of PDOM trees

SYNOPSIS
	 # Load a document
	 my $Module = PPI::Document->new( 'MyModule.pm' );

	 # Create the dumper
	 my $Dumper = PPI::Dumper->new( $Module );

	 # Dump the document
	 $Dumper->print;

DESCRIPTION
       The PDOM trees in PPI are quite complex, and getting a dump of their structure for
       development and debugging purposes is important.

       This module provides that functionality.

       The process is relatively simple. Create a dumper object with a particular set of options,
       and then call one of the dump methods to generate the dump content itself.

METHODS
   new $Element, param => value, ...
       The "new" constructor creates a dumper, and takes as argument a single PPI::Element object
       of any type to serve as the root of the tree to be dumped, and a number of key->value
       parameters to control the output format of the Dumper. Details of the parameters are
       listed below.

       Returns a new "PPI::Dumper" object, or "undef" if the constructor is not passed a correct
       PPI::Element root object.

       memaddr
	   Should the dumper print the memory addresses of each PDOM element.  True/false value,
	   off by default.

       indent
	   Should the structures being dumped be indented. This value is numeric, with the number
	   representing the number of spaces to use when indenting the dumper output. Set to '2'
	   by default.

       class
	   Should the dumper print the full class for each element.  True/false value, on by
	   default.

       content
	   Should the dumper show the content of each element. True/false value, on by default.

       whitespace
	   Should the dumper show whitespace tokens. By not showing the copious numbers of
	   whitespace tokens the structure of the code can often be made much clearer. True/false
	   value, on by default.

       comments
	   Should the dumper show comment tokens. In situations where you have a lot of comments,
	   the code can often be made clearer by ignoring comment tokens. True/value value, on by
	   default.

       locations
	   Should the dumper show the location of each token. The values shown are [ line,
	   rowchar, column ]. See "location" in PPI::Element for a description of what these
	   values really are. True/false value, off by default.

   print
       The "print" method generates the dump and prints it to STDOUT.

       Returns as for the internal print function.

   string
       The "string" method generates the dump and provides it as a single string.

       Returns a string or undef if there is an error while generating the dump.

   list
       The "list" method generates the dump and provides it as a raw list, without trailing
       newlines.

       Returns a list or the null list if there is an error while generation the dump.

SUPPORT
       See the support section in the main module.
