IntHashMap

java.lang.Object
- net.sf.saxon.sort.IntHashMap

All Implemented Interfaces:

java.io.Serializable
```
public class IntHashMap
extends java.lang.Object
implements java.io.Serializable
```
A hash table that maps int keys to Object values.

Author:

Dave Hale, Landmark Graphics, Dominique Devienne, Michael Kay: retrofitted to JDK 1.4, added iterator(), modified to disallow null values

- Constructor Detail
  - IntHashMap
```
public IntHashMap()
```
    Initializes a map with a capacity of 8 and a load factor of 0,25.
  - IntHashMap
```
public IntHashMap(int capacity)
```
    Initializes a map with the given capacity and a load factor of 0,25.
    
    Parameters:
    
    capacity - the initial capacity.
  - IntHashMap
```
public IntHashMap(int capacity,
                  double factor)
```
    Constructs a new map with initial capacity, and load factor.
    The capacity is the number of keys that can be mapped without resizing the arrays in which keys and values are stored. For efficiency, only a fraction of the elements in those arrays are used. That fraction is the specified load factor. The initial length of the arrays equals the smallest power of two not less than the ratio capacity/factor. The capacity of the map is increased, as necessary. The maximum number of keys that can be mapped is 2^30.
    
    Parameters:
    
    capacity - the initial capacity.
    
    factor - the load factor.
- Method Detail
  - clear
```
public void clear()
```
    Clears the map.
  - get
```
public java.lang.Object get(int key)
```
    Gets the value for this key.
    
    Parameters:
    
    key - Key
    
    Returns:
    
    the value, null if not found.
  - size
```
public int size()
```
    Gets the size of the map.
    
    Returns:
    
    the size (the number of entries in the map)
  - remove
```
public boolean remove(int key)
```
    Removes a key from the map.
    
    Parameters:
    
    key - Key to remove
    
    Returns:
    
    true if the value was removed
  - put
```
public java.lang.Object put(int key,
                            java.lang.Object value)
```
    Adds a key-value pair to the map.
    
    Parameters:
    
    key - Key
    
    value - Value
    
    Returns:
    
    the value that was previously associated with the key, or null if there was no previous value
  - keyIterator
```
public IntIterator keyIterator()
```
    Get an iterator over the keys
  - valueIterator
```
public java.util.Iterator valueIterator()
```
    Get an iterator over the values
  - copy
```
public IntHashMap copy()
```
    Create a copy of the IntHashMap
  - display
```
public void display()
```
    Diagnostic display of contents
