VectorUtils

- org.eclipse.persistence.internal.oxm.VectorUtils

```
public class VectorUtils
extends java.lang.Object
```
This class provides "empty" and "unmodifiable" wrappers for the Vector class. The functionality is similar the Collections class and mostly copy-paste from the class. Unfortunately, the standard Collections class does not provides wrappers for the outdated Vector class.

public static final java.util.Vector EMPTY_VECTOR

    The empty vector (immutable).

  - unmodifiableVector
```
public static <T> java.util.Vector<T> unmodifiableVector(java.util.Vector<? extends T> vector)
```
    Returns an unmodifiable view of the specified vector. This method allows modules to provide users with "read-only" access to internal vectors. Query operations on the returned vector "read through" to the specified vector, and attempts to modify the returned vector, whether direct or via its iterator, result in an UnsupportedOperationException.
    
    Type Parameters:
    
    T - the class of the objects in the vector
    
    Parameters:
    
    vector - the vector for which an unmodifiable view is to be returned.
    
    Returns:
    
    an unmodifiable view of the specified vector.
  - emptyVector
```
public static final <T> java.util.Vector<T> emptyVector()
```
    Returns an empty vector (immutable).
    This example illustrates the type-safe way to obtain an empty vector:
    Vector<String> s = VectorUtils.emptyVector();
    Type Parameters:
    
    T - type of elements, if there were any, in the vector
    
    Returns:
    
    an empty immutable vector
