Examples of java.util.Vector.removeElement()

java.util.Vector.removeElement()
Removes the first (lowest-indexed) occurrence of the argument from this vector. If the object is found in this vector, each component in the vector with an index greater or equal to the object's index is shifted downward to have an index one smaller than the value it had previously.
This method is identical in functionality to the {@link #remove(Object)} method (which is part of the{@link List} interface). @param obj the component to be removed @return {@code true} if the argument was a component of thisvector; {@code false} otherwise.

            try {
                Object value = locksCache.get(uri.toString());
                Vector locksVector = null;
                if (value != null) {
                    locksVector = new Vector((Vector)value);
                    boolean wasPresent = locksVector.removeElement(lock);
                    if (!wasPresent) {
                        throw new LockTokenNotFoundException(lock);
                    }
                }
                locksCache.put(uri.toString(), locksVector);
