ObjectVector (Xalan-Java 2.7.2)

java.lang.Object
- org.apache.xml.utils.ObjectVector

All Implemented Interfaces:

java.lang.Cloneable

Direct Known Subclasses:

ObjectStack
```
public class ObjectVector
extends java.lang.Object
implements java.lang.Cloneable
```
A very simple table that stores a list of objects. This version is based on a "realloc" strategy -- a simle array is used, and when more storage is needed, a larger array is obtained and all existing data is recopied into it. As a result, read/write access to existing nodes is O(1) fast but appending may be O(N**2) slow.

  - ObjectVector
```
public ObjectVector(int blocksize)
```
    Construct a IntVector, using the given block size.
    
    Parameters:
    
    blocksize - Size of block to allocate
  - ObjectVector
```
public ObjectVector(int blocksize,
                    int increaseSize)
```

    Parameters:
    
    blocksize - Size of block to allocate
  - ObjectVector
```
public ObjectVector(ObjectVector v)
```
    Copy constructor for ObjectVector
    
    Parameters:
    
    v - Existing ObjectVector to copy
- Method Detail
  - size
```
public final int size()
```
    Get the length of the list.
    
    Returns:
    
    length of the list
  - setSize
```
public final void setSize(int sz)
```
    Get the length of the list.
  - addElement
```
public final void addElement(java.lang.Object value)
```
    Append an object onto the vector.
    
    Parameters:
    
    value - Object to add to the list
  - addElements
```
public final void addElements(java.lang.Object value,
                              int numberOfElements)
```
    Append several Object values onto the vector.
    
    Parameters:
    
    value - Object to add to the list
  - addElements
```
public final void addElements(int numberOfElements)
```
    Append several slots onto the vector, but do not set the values.
    
    Parameters:
    
    numberOfElements - number of slots to append
  - insertElementAt
```
public final void insertElementAt(java.lang.Object value,
                                  int at)
```
    Inserts the specified object in this vector at the specified index. Each component in this vector with an index greater or equal to the specified index is shifted upward to have an index one greater than the value it had previously.
    
    Parameters:
    
    value - Object to insert
    
    at - Index of where to insert
  - removeAllElements
```
public final void removeAllElements()
```
    Remove all elements objects from the list.
  - removeElement
```
public final boolean removeElement(java.lang.Object s)
```
    Removes the first 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.
    
    Parameters:
    
    s - Object to remove from array
    
    Returns:
    
    True if the object was removed, false if it was not found
  - removeElementAt
```
public final void removeElementAt(int i)
```
    Deletes the component at the specified index. Each component in this vector with an index greater or equal to the specified index is shifted downward to have an index one smaller than the value it had previously.
    
    Parameters:
    
    i - index of where to remove an object
  - setElementAt
```
public final void setElementAt(java.lang.Object value,

```
    Sets the component at the specified index of this vector to be the specified object. The previous component at that position is discarded. The index must be a value greater than or equal to 0 and less than the current size of the vector.
