Which level of DevicePolicyManager password quality disables pattern password?

I am writing an android app which sets the password quality based on certain conditions. I can say with certainty that when password quality is set to PASSWORD_QUALITY_SOMETHING, the pattern password is available on the phone but when I set the password quality to PASSWORD_QUALITY_ALPHANUMERIC the pattern password is disabled on the phone. I just want to know which level of password quality disables the pattern password.

Have a look at base/core/java/com/android/internal/widget/LockPatternUtils.java, function getActivePasswordQuality().

PASSWORD_QUALITY_SOMETHING and PASSWORD_QUALITY_BIOMETRIC_WEAK enables the user to choose a pattern, increasing password quality to PASSWORD_QUALITY_NUMERIC or greater would not allow pattern kind of password.

List of password qualities are defined in base/core/java/android/app/admin/DevicePolicyManager.java
