getUnboxedFieldname

public static String getUnboxedFieldname(String name,
                                         String primitiveType)

getInBoxedFieldname

public static String getInBoxedFieldname(String name,
                                         String primitiveType)

toObjectType

public static String toObjectType(String primitiveType)

getField

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

setField
