Name
Unexpected::Functions - A collection of functions used in this distribution
Synopsis
use Unexpected::Functions qw( build_attr_from );
Description
A collection of functions used in this distribution
Also exports any exceptions defined by the caller's EXCEPTION_CLASS
as subroutines that return the subroutines name as a string. The calling package can then throw exceptions with a class attribute that takes these subroutines return values
Configuration and Environment
Defines no attributes
Subroutines/Methods
build_attr_from
$hash_ref = build_attr_from( <whatever> );
Coerces a hash ref from whatever args are passed
catch_class
use Try::Tiny;
try { die $exception_object }
catch_class [ 'exception_class' => sub { # handle exception }, ... ],
finally { # always do this };
See Try::Tiny::ByClass. Checks the exception object's class
attribute against the list of exception class names passed to catch_class
. If there is a match, call the subroutine provided to handle that exception. Re-throws the exception if there is no match of if the exception object has no class
attribute
has_exception
has_exception 'exception_name' => parents => [ 'parent_exception' ],
error => 'Error message for the exception with placeholders';
Calls "add_exception" in Unexpected::TraitFor::ExceptionClasses via the calling class which is assumed to inherit from a class that consumes the Unexpected::TraitFor::ExceptionClasses role
inflate_message
$message = inflate_message( $template, $arg1, $arg2, ... );
Substitute the placeholders in the $template
string (e.g. [_1]) with the corresponding argument
is_class_loaded
$bool = is_class_loaded $classname;
Returns true is the classname as already loaded and compiled
quote_bind_values
$bool = Unexpected::Functions->quote_bind_values( $bool );
Accessor / mutator package method that toggles the state on quoting the placeholder substitution values in inflate_message
. Defaults to true

None
