方法详细资料

accessLevel

public static int accessLevel(int accessFlags)

Returns the corresponding access level of the given access flags.

参数:

accessFlags - the internal access flags as a logical bit mask of AccessConstants.PRIVATE, AccessConstants.PROTECTED, and AccessConstants.PUBLIC.

返回:

the corresponding access level: PRIVATE, PACKAGE_VISIBLE, PROTECTED, or PUBLIC.

accessFlags

public static int accessFlags(int accessLevel)

Returns the corresponding access flags of the given access level.

参数:

accessLevel - the access level: PRIVATE, PACKAGE_VISIBLE, PROTECTED, or PUBLIC.

返回:

the corresponding internal access flags as a logical bit mask of AccessConstants.PRIVATE, AccessConstants.PROTECTED, and AccessConstants.PUBLIC.

replaceAccessFlags

public static int replaceAccessFlags(int accessFlags,
                                     int newAccessFlags)

Replaces the access part of the given access flags.

参数:

accessFlags - the internal access flags as a logical bit mask of AccessConstants.PRIVATE, AccessConstants.PROTECTED, and AccessConstants.PUBLIC.

newAccessFlags - the new access flags as a logical bit mask of AccessConstants.PRIVATE, AccessConstants.PROTECTED, and AccessConstants.PUBLIC.

返回:

the modified access flags.

accepted

public static boolean accepted(int accessFlags,
                               int requiredSetAccessFlags,
                               int requiredUnsetAccessFlags)

Returns whether the given access flags match the required set and unset access flags.

参数:

accessFlags - the internal access flags as a logical bit mask of AccessConstants.PRIVATE, AccessConstants.PROTECTED, and AccessConstants.PUBLIC.

requiredSetAccessFlags - the internal access flags that should be set, as a logical bit mask of AccessConstants.PRIVATE, AccessConstants.PROTECTED, and AccessConstants.PUBLIC.

requiredUnsetAccessFlags - the internal access flags that should be unset, as a logical bit mask of AccessConstants.PRIVATE, AccessConstants.PROTECTED, and AccessConstants.PUBLIC.

返回:

whether the access flags match the requirements.
