Version

This documents version v0.19.$Rev: 1 $ of File::DataClass::Exception

Description

An exception class that supports error messages with placeholders, a "throw" in File::DataClass::Exception::TraitFor::Throwing method with automatic re-throw upon detection of self, conditional throw if an exception was caught and a simplified stacktrace

Error objects are overloaded to stringify to the full error message plus a leader

Applies exception roles to the exception base class File::DataClass::Exception::Base. See "Dependencies" for the list of roles that are applied

Configuration and Environment

The File::DataClass::Exception->Ignore class attribute is an array ref of methods whose presence should be ignored by the error message leader. It does the 'Array' trait where push implements the ignore_class method

Subroutines/Methods
