Class IntVector
java.lang.Object
org.apache.xml.utils.IntVector
- Cloneable
public class IntVector
extends java.lang.Object
implements Cloneable
A very simple table that stores a list of int.
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. See also SuballocatedIntVector.

IntVector
public IntVector()
Default constructor. Note that the default
block size is very small, for small lists.
IntVector
public IntVector(int blocksize)
Construct a IntVector, using the given block size.
blocksize
- Size of block to allocate
IntVector
public IntVector(int blocksize,
int increaseSize)
Construct a IntVector, using the given block size.
blocksize
- Size of block to allocate
IntVector
public IntVector(IntVector v)
Copy constructor for IntVector
v
- Existing IntVector to copy
addElement
public final void addElement(int value)
Append a int onto the vector.
value
- Int to add to the list
addElements
public final void addElements(int numberOfElements)
Append several slots onto the vector, but do not set the values.
addElements
public final void addElements(int value,
int numberOfElements)
Append several int values onto the vector.
value
- Int to add to the list
clone
public Object clone()
throws CloneNotSupportedException
Returns clone of current IntVector
- clone of current IntVector
contains
public final boolean contains(int s)
Tell if the table contains the given node.
- true if the object is in the list
elementAt
public final int elementAt(int i)
Get the nth element.
i
- index of object to get
indexOf
public final int indexOf(int elem)
Searches for the first occurence of the given argument,
beginning the search at index, and testing for equality
using the equals method.
elem
- object to look for
- the index of the first occurrence of the object
argument in this vector at position index or later in the
vector; returns -1 if the object is not found.
indexOf
public final int indexOf(int elem,
int index)
Searches for the first occurence of the given argument,
beginning the search at index, and testing for equality
using the equals method.
elem
- object to look forindex
- Index of where to begin search
- the index of the first occurrence of the object
argument in this vector at position index or later in the
vector; returns -1 if the object is not found.
insertElementAt
public final void insertElementAt(int value,
int at)
Inserts the specified node 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.
value
- Int to insertat
- Index of where to insert
lastIndexOf
public final int lastIndexOf(int elem)
Searches for the first occurence of the given argument,
beginning the search at index, and testing for equality
using the equals method.
elem
- Object to look for
- the index of the first occurrence of the object
argument in this vector at position index or later in the
vector; returns -1 if the object is not found.
removeAllElements
public final void removeAllElements()
Inserts the specified node 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.
removeElement
public final boolean removeElement(int 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.
s
- Int to remove from array
- True if the int 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.
i
- index of where to remove and int
setElementAt
public final void setElementAt(int value,
int index)
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.
index
- Index of where to set the object
setSize
public final void setSize(int sz)
Get the length of the list.
size
public final int size()
Get the length of the list.
