BeanUtil

public BeanUtil()

Method Details

isPrimitive

public static boolean isPrimitive(Object val)

isPrimitive

public static boolean isPrimitive(@NonNull
 @NonNull Class<?> clazz)

getCollectionParameterizeType

public static Class<?> getCollectionParameterizeType(@NonNull
 @NonNull Parameter parameter)

copyFields

public static <E> void copyFields(@NonNull
 E source,
 @NonNull
 E target)

Copy Object source to Object target. This coping is not recursive. If a source field is Collection, it's element will be Collection.addAll(Collection) to corresponding target field, instead of copy the Collection reference. Hence if target's Collection is not initialized and remains null, it won't be copied.

copyFieldsExcluding

public static <E> void copyFieldsExcluding(@NonNull
 E source,
 @NonNull
 E target,
 String... fields)

Parameters:

fields - to be excluded for copying

See Also:

• copyFields(Object, Object)

copyFieldsIncluding

public static <E> void copyFieldsIncluding(@NonNull
 E source,
 @NonNull
 E target,
 String... fields)

Parameters:

fields - to be included for copying

See Also:

• copyFields(Object, Object)

copyFields

public static <E> void copyFields(@NonNull
 E source,
 @NonNull
 E target,
 boolean ignoreNullField,
 boolean includeOrExclude,
 String... fields)

getFieldValue

public static <T> T getFieldValue(@NotNull
 @NotNull Object target,
 @NotNull
 @NotNull String path)

getFieldClass

public static Class<?> getFieldClass(@NonNull
 @NonNull Object target,
 @NonNull
 @NonNull String fieldName)

setFieldValue

public static void setFieldValue(@NonNull
 @NonNull Object target,
 @NonNull
 @NonNull String fieldName,
 Object value)

deepClone

public static <T extends Serializable> T deepClone(@NonNull
 T o)

getDeclaredMethod

public static Method getDeclaredMethod(@NonNull
 @NonNull Class<?> clazz,
 @NonNull
 @NonNull String methodName,
 Class<?>... parameterTypes)

getMethod

public static Method getMethod(@NonNull
 @NonNull Class<?> clazz,
 @NonNull
 @NonNull String methodName,
 Class<?>... parameterTypes)

callMethod

public static <R,
O> R callMethod(O object,
 @NonNull
 @NonNull String methodName,
 Object... parameters)

callMethod

public static <R> R callMethod(Class<?> clazz,
 Object object,
 @NonNull
 @NonNull String methodName,
 Object... parameters)

This method doesn't always function as expected. Be 100% sure and tested when you use it. As known, this method is not worked for following case: * parameter type is primitive number, e.g. int.class * parameter type is general type, e.g. Object.class
