ConstructorBasedConverter (Vert.x Stack - Docs 5.0.0.CR3 API)

java.lang.Object
- io.vertx.core.cli.converters.ConstructorBasedConverter<T>

All Implemented Interfaces:

Converter<T>
```
public final class ConstructorBasedConverter<T>
extends Object
implements Converter<T>
```
This 'default' converter tries to create objects using a constructor taking a single String argument. Be aware that implementation must also handle the case where the input is null.

- Method Detail
  - getIfEligible
```
public static <T> ConstructorBasedConverter<T> getIfEligible(Class<T> clazz)
```
    Checks whether the given class can be used by the ConstructorBasedConverter (i.e. has a constructor taking a single String as argument). If so, creates a new instance of converter for this type.
    
    Parameters:
    
    clazz - the class
    
    Returns:
    
    a ConstructorBasedConverter if the given class is eligible, null otherwise.
  - fromString
```
public T fromString(String input)
             throws IllegalArgumentException
```
    Converts the given input to an object by using the constructor approach. Notice that the constructor must expect receiving a null value.
    
    Specified by:
    
    fromString in interface Converter<T>
    
    Parameters:
    
    input - the input, can be null
    
    Returns:
    
    the instance of T
    
    Throws:
    
    IllegalArgumentException - if the instance of T cannot be created from the input.
