PPIx::EditorTools::ReturnObject(3pm)

NAME

PPIx::EditorTools::ReturnObject - Simple object to return values from PPIx::EditorTools

VERSION

version 0.21

SYNOPSIS

  my $brace = PPIx::EditorTools::FindUnmatchedBrace->new->find(
        code => "package TestPackage;\nsub x { 1;\n"
      );
  my $location = $brace->element->location;
  my $ppi      = $brace->element->ppi;

DESCRIPTION

Retuning a simple "PPI::Element" from many of the "PPIx::EditorTools" methods often results in the loss of the overall context for that element. "PPIx::EditorTools::ReturnObject" provides an object that can be passed around which retains the overall context.

For example, in "PPIx::EditorTools::FindUnmatchedBrace" if the unmatched brace were returned by its "PPI::Structure::Block" the containing "PPI::Document" is likely to go out of scope, thus the "location" method no longer returns a valid location (rather it returns undef). Using the "ReturnObject" preserves the "PPI::Document" and the containing context.

METHODS

new()

Constructor which should be used by "PPIx::EditorTools". Accepts the following named parameters:

ppi: A "PPI::Document" representing the (possibly modified) code.

code: A string representing the (possibly modified) code.

element: A "PPI::Element" or a subclass thereof representing the interesting element.

ppi: Accessor to retrieve the "PPI::Document". May create the "PPI::Document" from the $code string (lazily) if needed.

code: Accessor to retrieve the string representation of the code. May be retrieved from the "PPI::Document" via the serialize method (lazily) if needed.
