Method Details

unmodifiable

public PreconditionFailed unmodifiable()

Description copied from class: BasicHttpException

Returns an unmodifiable snapshot of this bean.

The returned instance is a point-in-time copy of the leaf's nested Unmodifiable type; any attempt to set a property on it throws an UnsupportedOperationException. This method is idempotent: if this bean is already unmodifiable it returns itself rather than taking another snapshot. The receiver is left unchanged (and still modifiable unless it was already unmodifiable).

Overrides:

unmodifiable in class BasicHttpException

Returns:

An unmodifiable snapshot of this bean, or this bean if it is already unmodifiable.
