Method Detail

exists

boolean exists()

Check if the key that represents the constraint exists. It does not matter whether the value of the key is null or not.

For example, exists() method of an instance that represents given_name in the JSON below will return true.

 {
   "verified_claims": {
     "claims": {
       "given_name": null
     }
   }
 }
 

Returns:

true if the key that represents the constraint exists.

isNull

boolean isNull()

Check if the value of the constraint is null.

For example, isNull() method of an instance that represents given_name in the JSON below will return true.

 {
   "verified_claims": {
     "claims": {
       "given_name": null
     }
   }
 }
 

But, the method returns false in the following case.

 {
   "verified_claims": {
     "claims": {
       "given_name": {
       }
     }
   }
 }
 

Returns:

true if the value of the constraint is null.
