Class GenericTypeBuilder<T>

java.lang.Object

net.sf.mmm.util.reflect.base.GenericTypeCapture<T>

net.sf.mmm.util.reflect.base.GenericTypeBuilder<T>

Type Parameters:

T - the generic type of the GenericType to build() after type variables have been bound.

public abstract class GenericTypeBuilder<T>
extends GenericTypeCapture<T>

This class allows to build instances of GenericType with custom binding for TypeVariables at runtime. The following example illustrates the usage:

 public static GenericType<List<Provider<T>>> typeOfListOfProviderOf(GenericType<T> type) {
   return new GenericTypeBuilder<List<Provider<T>>>() {}
              .with(new GenericTypeVariable<T>() {}, type)
              .build();
 }
