Interface ObjectTransformer<T,E>

Type Parameters:

T - The type of the target value of the instance of this interface.

E - The type of the target value of the checker instance. In most cases, the same type as T is chosen.

All Superinterfaces:

AbstractObjectTransformer<ObjectTransformer<T,E>,ObjectChecker<T,E>,T,E>, Matcher<ObjectTransformer<T,E>,T,E>, Statement<T>, Transformer<ObjectTransformer<T,E>,ObjectChecker<T,E>,T,E>

All Known Implementing Classes:

ObjectTransformer.Impl

public interface ObjectTransformer<T,E>
extends AbstractObjectTransformer<ObjectTransformer<T,E>,ObjectChecker<T,E>,T,E>

This interface is used for object whose type doesn’t have an explicit support. Do not try to extend/implement this class to support your own class.

Lets the framework know the value to be checked is a Integer. This method may throw an exception, if the value is not a Integer.

Returns:

A <T> object.

asLong

default LongTransformer<T> asLong()

Lets the framework know the value to be checked is a Long. This method may throw an exception, if the value is not a Long.

Returns:

A <T> object.

asShort

default ShortTransformer<T> asShort()

Lets the framework know the value to be checked is a Short. This method may throw an exception, if the value is not a Short.

Returns:

A <T> object.

asDouble

default DoubleTransformer<T> asDouble()

Lets the framework know the value to be checked is a Double. This method may throw an exception, if the value is not a Double.

Returns:

A <T> object.

asFloat

default FloatTransformer<T> asFloat()

Lets the framework know the value to be checked is a Float. This method may throw an exception, if the value is not a Float.

Returns:

A <T> object.

asBoolean

default BooleanTransformer<T> asBoolean()

Lets the framework know the value to be checked is a Boolean. This method may throw an exception, if the value is not a Boolean.

Returns:

A <T> object.

asListOf

default <EE> ListTransformer<T,EE> asListOf(Class<EE> type)

Lets the framework know the value to be checked is a List of EE. This method may throw an exception, if the value is not a List.

Returns:

A <EE> object.

asList

default <EE> ListTransformer<T,EE> asList()

Lets the framework know the value to be checked is a List. This method may throw an exception, if the value is not a List.

Returns:
