Type-ex

Type-ex it’s a library to make easy application errors classification.

Motivation

In the old times all application errors were indexed in never-ending lists in big manuals to describe the possible problems and its solutions.

Quick start

1. First of all include the Jar file in your compile and execution classpath. Maven

    <dependency>
        <groupId>org.bytemechanics</groupId>
        <artifactId>type-ex</artifactId>
        <version>X.X.X</version>
    </dependency>
   

   Graddle

   dependencies {
    compile 'org.bytemechanics:type-ex:X.X.X'
   }
   

2. Create your typified exceptions

   package mypackage;
   import org.bytemechanics.typeex.impl.TypifiedException;
   public enum MyExceptionType implements ExceptionType<TypifiedException>{
    EXCEPTION_TYPE_NO_PARAMETERIZED("This message has no substitution parameters"),
    EXCEPTION_TYPE_PARAMETERIZED("This message has two {} substitution parameters {}"),
    ;	
    private final String message;
    MyExceptionType(final String _message){
        this.message=_message;
    }	
    @Override
    public String getMessage() {
        return this.message;
    }
   }
   

3. Launch an exception Manually

   throw MyExceptionType.EXCEPTION_TYPE_PARAMETERIZED
                        .from(cause)
                        .with("String1",1);
   

   From lambda

   Optional.of(null)
        .orElseThrow(MyExceptionType.EXCEPTION_TYPE_PARAMETERIZED
                        .from(cause)
                        .with("String1",1))
