Returns a new TypeResolver with type variables in formal mapping to types in actual .

Usage

From source file:org.assertj.core.test.TypeCanonizer.java

/**
 * Returns a canonical form of {@code initialType} by replacing all {@link TypeVariable} by {@link Class}
 * instances./*from  w w  w.  ja v a2  s  .com*/
 * <p>
 * <p>
 * Such a canonical form allows to compare {@link ParameterizedType}s, {@link WildcardType}(s),
 * {@link GenericArrayType}(s), {@link TypeVariable}(s).
 * </p>

    if (doesNotNeedCanonization(initialType)) {

    }

    ReplacementClassSupplier replacementClassSupplier = new ReplacementClassSupplier();
    TypeResolver typeResolver = new TypeResolver();

    for (TypeVariable<?> typeVariable : findAllTypeVariables(initialType)) {
        // Once we have all TypeVariable we need to resolve them with actual classes so the typeResolver can resolve
        // them properly
        typeResolver = typeResolver.where(typeVariable, replacementClassSupplier.get());
    }

    return typeResolver.resolveType(initialType);
