Element Detail

value

public abstract String value

Returns:

the permission name

before

public abstract boolean before

Set the time of check method access permission, usually it should be true But in rare case when it needs to check after the method executed (e.g. constructor) then it could be set to false;

Returns:

Default:

true

target

public abstract int target

Indicate which object should be used to check against with account. This only impact dynamic right checking

• 0: Set the current object on which the method is invoked to be the target. If the invoking method is static then it will set the first parameter as ; the target object. If there is no parameter at all then no target object will be set
• n (n > 0): Set the nth parameter as the target object. Note if n is larger than the number of parameters then a runtime exception will be thrown out when executing the method
• -1: Set the return object as the target object.

  Note

  • If there is no return object (method is void) then a runtime exception will be thrown out
  • When use -1 then the @{link #before()} shall be set to false as permission check happened when the method returned. if the -1 is used and before() is true, then enhancer will throw out a RuntimeException
  • When 0 is set to RR on a constructor, then -1 will be used instead
• n (n < -1): Nothing will be set as target object

Returns:

target code

Default:

0
