Method Detail

newParameterizedType

public static java.lang.reflect.ParameterizedType newParameterizedType(java.lang.reflect.Type rawType,
                                                                       java.lang.reflect.Type... typeArguments)

Returns a new parameterized type, applying typeArguments to rawType.

arrayOf

public static java.lang.reflect.GenericArrayType arrayOf(java.lang.reflect.Type componentType)

Returns an array type whose elements are all instances of componentType.

subtypeOf

public static java.lang.reflect.WildcardType subtypeOf(java.lang.reflect.Type bound)

Returns a type that represents an unknown type that extends bound. For example, if bound is CharSequence.class, this returns ? extends CharSequence. If bound is Object.class, this returns ?, which is shorthand for ? extends Object.

supertypeOf

public static java.lang.reflect.WildcardType supertypeOf(java.lang.reflect.Type bound)

Returns a type that represents an unknown supertype of bound. For example, if bound is String.class, this returns ? super String.

getRawType

public static java.lang.Class<?> getRawType(java.lang.reflect.Type type)

collectionElementType

public static java.lang.reflect.Type collectionElementType(java.lang.reflect.Type context,
                                                           java.lang.Class<?> contextRawType)

Returns the element type of this collection type.

Throws:

java.lang.IllegalArgumentException - if this type is not a collection.
