public VectorAccess(java.util.Vector vector)

Construct an VectorAccess object which wraps a java.util.Vector

Parameters:

vector - a Vector

Method Detail

get

public java.lang.Object get(int index)

Get a value via an integer index. This is like an array reference.

Specified by:

get in interface IndexedGetInterface

Parameters:

index - the index of the item to fetch.

Returns:

Object the object associated with the index.

Throws:

java.lang.IndexOutOfBoundsException - The implementor of this interface may throw this RuntimeException if the index is not valid.

set

public void set(int index,
                java.lang.Object object)

Set a value via an integer index. This is like an array element assignment.

Specified by:

set in interface IndexedSetInterface

Parameters:

index - the index of the item to store

Object - the object to store or associate with the index.

Throws:

java.lang.IndexOutOfBoundsException - The implementor of this interface may throw this RuntimeException if the index is not valid.

count

public int count()

Returns the number of items in the vector

Specified by:

count in interface com.sas.util.Countable

Returns:

the number of items in the vector

clone

public java.lang.Object clone()
                       throws java.lang.CloneNotSupportedException

Clone the object. This does not clone the vector.

Specified by:

clone in interface com.sas.PublicClonable

Overrides:

clone in class java.lang.Object

Returns:

a clone of this VectorAccess object

Throws:

java.lang.CloneNotSupportedException - if the string comparator cannot be cloned.
