类 UnsafeFieldGetter<T>

java.lang.Object

xdean.reflect.getter.impl.UnsafeFieldGetter<T>

类型参数:

T -

所有已实现的接口:

FieldGetter<T>, InvokeGetter<T,Field>, PropertyGetter<T>

public class UnsafeFieldGetter<T>
extends Object
implements FieldGetter<T>

Based on Unsafe.
Supports all java class, but limit by primitive type field amount. For each primitive type with n bytes size, there at most have 2^n this type fields. For example, construct UnsafeFieldGetter with a class with 3 boolean fields will lead a IllegalArgumentException.

构造器详细资料

UnsafeFieldGetter

public UnsafeFieldGetter(Class<T> clz)
                  throws IllegalStateException,
                         IllegalArgumentException

参数:

clz -

抛出:

IllegalStateException - If construct the mock object failed.

IllegalArgumentException - If the class is not suitable. See the class doc.

方法详细资料

getMockObject

public T getMockObject()

Get the mocked object. You can perform invocation on it directly.
For example:

 
 UnsafeFieldGetter getter = new UnsafeFieldGetter(SomeClass.class);
 getter.getName(o -> o.prop);
 // is same as
 SomeClass sc = getter.getMockObject();
 getter.getName(sc.prop);
 
 

返回:

supportFieldInvoke

public boolean supportFieldInvoke()

从接口复制的说明: PropertyGetter

Whether the direct field invoke is supported. If return true, you can use:

 
  PropertyGetter pg = ...;
  pg.getName(b -> b.beanProp);
 
 

指定者:

supportFieldInvoke 在接口中 PropertyGetter<T>

返回:

get

public Field get(java.util.function.Function<T,?> invoke)

指定者:

get 在接口中 InvokeGetter<T,Field>
