Overview

Finds the location of a variable declaration.

Methods

new()

Constructor. Generally shouldn't be called with any arguments.

find( ppi => PPI::Document $ppi, line => $line, column => $column )

find( code => Str $code, line => $line, column => $column )

Accepts either a "PPI::Document" to process or a string containing the code (which will be converted into a "PPI::Document") to process. Searches for the variable declaration and returns a "PPIx::EditorTools::ReturnObject" with the declaration ("PPI::Statement::Variable") available via the "element" accessor.

Croaks with a "no token" exception if no token is found at the location. Croaks with a "no declaration" exception if unable to find the declaration.
