public void setMfaDeleteEnabled(Boolean mfaDeleteEnabled) {
        isMfaDeleteEnabled = mfaDeleteEnabled;
    }
Sets the status of Multi-Factor Authentication (MFA) Delete for a bucket.
When MFA Delete is enabled, object versions can only be permanently
deleted when the bucket owner passes in, as part of a delete version
request, an MFA token from the hardware token generator associated with
their Amazon Web Services account.
<p>
By default, MFA Delete is <b>not</b> enabled.
<p>
When enabling or disabling MFA Delete controls, you <b>must</b> also
supply an MFA token from the hardware token generator as part of the
request.

@param mfaDeleteEnabled
           True if the Multi-Factor Authentication (MFA) Delete is being
           enabled enabled, false if it is being disabled.
