Description

An exception class that inherits from a custom subclass of Exception::Class

Subroutines/Methods

new

Create an exception object. You probably do not want to call this directly, but indirectly through "catch" and "throw"

catch

$e = File::DataClass::Exception->catch( $error );

Catches and returns a thrown exception or generates a new exception if EVAL_ERROR has been set

full_message

$printable_string = $e->full_message

What an instance of this class stringifies to

stacktrace

$lines = $e->stacktrace( $num_lines_to_skip );

Return the stack trace. Defaults to skipping one (the first) line of output

throw

File::DataClass::Exception->throw( $error );

Create (or re-throw) an exception to be caught by the catch above. If the passed parameter is a reference it is re-thrown. If a single scalar is passed it is taken to be an error message code, a new exception is created with all other parameters taking their default values. If more than one parameter is passed the it is treated as a list and used to instantiate the new exception. The 'error' parameter must be provided in this case

throw_on_error

File::DataClass::Exception->throw_on_error $error );

Calls "catch" and if the was an exception "throw"s it

Diagnostics

None
