Method Summary

Modifier and Type	Method and Description
static <T> T	checkNotNull(T t, java.lang.String message)
static void	closeIO(java.io.Closeable... closeables) 关闭 IO
static int	getAppVersionCode(android.content.Context context) 获取 App 版本码
static java.lang.String	getCacheKey(ProceedingJoinPoint joinPoint) 获取缓存的key
static java.lang.String	getClassName(java.lang.Class<?> cls)
static java.io.File	getDiskCacheDir(android.content.Context context, java.lang.String uniqueName) 应用程序缓存原理： 1.当SD卡存在或者SD卡不可被移除的时候，就调用getExternalCacheDir()方法来获取缓存路径，否则就调用getCacheDir()方法来获取缓存路径 2.前者是/sdcard/Android/data//cache 这个路径 3.后者获取到的是 /data/data//cache 这个路径

public static java.lang.String listToString(java.util.List<java.lang.String> list,
                                            java.lang.String separator)

根据分隔符将List转换为String

Parameters:

list -

separator -

Returns:

listToString

public static java.lang.String listToString(java.util.List<java.lang.String> list)

根据分隔符将List转换为String

Parameters:

list -

Returns:

getClassName

public static java.lang.String getClassName(java.lang.Class<?> cls)

toString

public static java.lang.String toString(java.lang.Object object)

getMethodDescribeInfo

public static java.lang.String getMethodDescribeInfo(ProceedingJoinPoint joinPoint)

获取方法的描述信息

Parameters:

joinPoint -

Returns:

getMethodName

public static java.lang.String getMethodName(ProceedingJoinPoint joinPoint)

获取简约的方法名

Parameters:

joinPoint -

Returns:

checkNotNull

public static <T> T checkNotNull(T t,
                                 java.lang.String message)

closeIO

public static void closeIO(java.io.Closeable... closeables)

关闭 IO

Parameters:

closeables - closeables

getDiskCacheDir

public static java.io.File getDiskCacheDir(android.content.Context context,
                                           java.lang.String uniqueName)

应用程序缓存原理： 1.当SD卡存在或者SD卡不可被移除的时候，就调用getExternalCacheDir()方法来获取缓存路径，否则就调用getCacheDir()方法来获取缓存路径
2.前者是/sdcard/Android/data//cache 这个路径
3.后者获取到的是 /data/data//cache 这个路径

Parameters:

uniqueName - 缓存目录

获取缓存的key

Parameters:

joinPoint -

Returns:

isHasReturnType

public static boolean isHasReturnType(Signature signature)

方法是否有返回值

Parameters:

signature -

Returns:

isEmpty

public static boolean isEmpty(java.lang.Object obj)

返回object是否为空

Parameters:

obj - The object.

Returns:

true: yes
false: no
