public static Object getField(Object t,
                              String name)

Get the field represented by the supplied field object on the specified target object. In accordance with Field.get(Object) semantics, the returned value is automatically wrapped if the underlying field has a primitive type.

Thrown exceptions are handled via a call to

参数:

t - the target object from which to get the field

name - the field to get

返回:

the field's current value

setField

public static void setField(Object t,
                            String name,
                            Object value)

Set the field represented by the supplied field object on the specified target object to the specified value. In accordance with Field.set(Object, Object) semantics, the new value is automatically unwrapped if the underlying field has a primitive type.

Thrown exceptions are handled via a call to

参数:

t - the target object on which to set the field

name - the field to set

value - the value to set; may be null

findField

public static Field findField(Class clazz,
                              String name)

the corresponding Field object, or null if not found

findField

public static Field findField(Class clazz,
                              String name,
                              Class type)

Attempt to find a field on the supplied Class with the supplied name and/or type. Searches all superclasses up to Object.

参数:

clazz - the class to introspect

name - the name of the field (may be null if type is specified)

type - the type of the field (may be null if name is specified)
