typeVariable

public static <D extends GenericDeclaration> TypeVariable<D> typeVariable(D declaration,
                                                                          String name,

Creates a type variable for the specified declaration, name and bounds.

Type Parameters:

D - the type of generic declaration that declared the type variable

Parameters:

declaration - the generic declaration that declared the type variable

name - the name of the type variable

bounds - the upper bounds of the type variable

Returns:

the type variable

genericArrayType

public static GenericArrayType genericArrayType(Type componentType)

Creates a generic array type for the specified component type.

Parameters:

componentType - the component type

Returns:

the generic array type

parameterizedType

public static ParameterizedType parameterizedType(Class<?> rawType,
                                                  Type... actualTypeArguments)

Creates a parameterized type for the specified raw type and actual type arguments.

Parameters:

rawType - the raw type

actualTypeArguments - the actual type arguments

Returns:

the parameterized type

Throws:

MalformedParameterizedTypeException - if the number of actual type arguments differs from those defined on the raw type

unboundedWildcardType

public static WildcardType unboundedWildcardType()

Creates an unbounded wildcard type.

Returns:

the wildcard type

upperBoundedWildcardType

public static WildcardType upperBoundedWildcardType(Type upperBound)

Creates a wildcard type with the specified upper bound.

Parameters:

upperBound - the upper bound type

Returns:

the wildcard type

lowerBoundedWildcardType

public static WildcardType lowerBoundedWildcardType(Type lowerBound)

Creates a wildcard type with the specified lower bound.

Parameters:

lowerBound - the lower bound type

Returns:

the wildcard type

valueOf

public static Type valueOf(String typeName)

Returns a type that corresponds to the specified string.

Parameters:

typeName - the string to be parsed

Returns:

the type

valueOf

public static Type valueOf(String typeName,
                           Set<String> imports)

Returns a type that corresponds to the specified string using the specified import context.

Parameters:

typeName - the string to be parsed

imports - the fully qualified class names to use when an unqualified class name is encountered

Returns:

the type

Throws:

IllegalArgumentException - if the import context contains duplicate entries for an unqualified class name
