方法详细资料

isPrimitive

public static boolean isPrimitive(Type type)

judge a type is a primitive type or not

judge a type is a array or not

isClass

public static boolean isClass(Type type)

judge a type is a class or not

isParameterizedType

judge a type is a ParameterizedType

getPrimitiveWrapClass

public static Class getPrimitiveWrapClass(Type type)

get the wrap class for a primitive type

typeToString

public static String typeToString(Type type)

show a type as a string, for examples:

getTypeSignature

public static String getTypeSignature(@NonNull
                                      String typeString)

get the type's signature in jvm runtime

参数:

typeString - type FQN

返回:

signature

arrayOf

public static GenericArrayType arrayOf(Type componentType)

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

返回:

a serializable generic array type.

equal

public static boolean equal(Object a,
                            Object b)

equals

public static boolean equals(Type a,
                             Type b)

Returns true if a and b are equal.

getRawType

convert any type to Class

参数:

o -

返回:

getSetParameterizedType

public static ParameterizedType getSetParameterizedType(Type elementType)

     List
 

getListParameterizedType

public static ParameterizedType getListParameterizedType(Type elementType)

     List
 

getMapParameterizedType

public static ParameterizedType getMapParameterizedType(Type keyType,
                                                        Type valueType)

     Map
 

getParameterizedType

public static ParameterizedType getParameterizedType(Type rawType)

getParameterizedType

public static ParameterizedType getParameterizedType(Type rawType,
                                                     Type... typeArguments)

getParameterizedTypeWithOwnerType

public static ParameterizedType getParameterizedTypeWithOwnerType(Type ownerType,
                                                                  Type rawType,

checkPrimitiveArray

public static Type checkPrimitiveArray(GenericArrayType genericArrayType)

resolve

public static Type resolve(Type context,
                           Class<?> contextRawType,
                           Type toResolve)
