Throwing meaningful and semantic exceptions with interfaces

Exception class names contain no word "Exception" in it. This is a redundant information and it is easier to understand and to read.

Usage:

use JBR\Exceptionist\InvalidArgument;
use JBR\Exceptionist\InvalidityReason:

function throwsAnException() {
    throw new InvalidArgument('An Argument is invalid');
}

try {
    throwsAnException();
} catch (InvalidityReason $e) {
    echo $e->getMessage();
}

use JBR\Exceptionist\EmptyArgument;
use JBR\Exceptionist\InvalidityReason:
use JBR\Exceptionist\DeficiencyReason;

function throwsAlsoAnException() {
    throw new EmptyArgument('An Argument is empty');
}

try {
    throwsAlsoAnException();
} catch (InvalidityReason|DeficiencyReason $e) {
    echo $e->getMessage();
}

Kind of exceptions:

• Empty
  • something is set, but have empty content
• Invalid
  • something is set, but has invalid characters or is in an invalid format
• Unknown
  • something is set, but it is unknown (not invalid)
• Missing
  • something is set, but its needs is missing
• Timeout
  • something is set, but it cannot be read in a particular time window

Kind of reasons:

• Absence
  • something is not reachable in a particular time window
• Compatibility
  • something is broken by compatibility
• Deficiency
  • something is needed, but is absent
• Invalidity
  • something is needed, but is invalid

Kind of scopes:

• Access
  • something with accessibilities
• Action
  • something with actions
• Argument
  • something with arguments of a method
  • something with arguments of an object
• Class
  • something with class instancing
• Configuration
  • something with configuration
• Declaration
  • something with declarations
• Definition
  • something with definitions
• Dependency
  • something with dependencies
• Interface
  • something with interfaces
• Method
  • something with methods of an object
• Object
  • something with objects
• Property
  • something with properties of an object
• Reference
  • something with references
• Requirement
  • something with requirements
• Return
  • something with returns of an object
  • something with returns of an method
• Trait
  • something with traits
• Type
  • something with types of a return
  • something with types of a method
  • something with types of an object
• Value
  • something with value

Compose exceptions for your application:

Create an interface or a trait for your application - so you are able to catch only the exceptions of your application.

interface YourApplication {
}

Create your exception:

use JBR\Exceptionist\InvalidParser;

class InvalidParserType extends InvalidParser implements YourApplication {

}
