NAME

Data::Object::Role::Tryable

ABSTRACT

Data-Object Tryable Role

SYNOPSIS

  use Data::Object::Class;

  use Data::Object::Role::Tryable;

  my $try = $self->try($method);

  $try->catch($type, fun ($caught) {
    # caught an exception

    return $something;
  });

  $try->default(fun ($caught) {
    # catch the uncaught

    return $something;
  });

  $try->finally(fun ($self, $caught) {
    # always run after try/catch
  });

  my $result = $try->result;

DESCRIPTION

This role provides a wrapper around the Data::Object::Try class which provides an object-oriented interface for performing complex try/catch operations.

LIBRARIES

This package uses type constraints defined by:

Data::Object::Library

METHODS

This package implements the following methods.

try

  try(Str | CodeRef $method) : Object

The try method takes a method name or coderef and returns a Data::Object::Try object with the current object passed as the invocant which means that try and finally callbacks will receive that as the first argument.

try example

  my $try;

  $try = $self->try($method);
  $try = $self->try(fun ($self) {
    # do something

    return $something;
  });
