org.apache.xalan.xsltc.runtime.Hashtable
public class Hashtable
extends java.lang.Object
The main hash-table implementation
Hashtable() - Constructs a new, empty hashtable with a default capacity and load
factor.
|
Hashtable(int initialCapacity) - Constructs a new, empty hashtable with the specified initial capacity
and default load factor.
|
Hashtable(int initialCapacity, float loadFactor) - Constructs a new, empty hashtable with the specified initial
capacity and the specified load factor.
|
void | clear() - Clears this hashtable so that it contains no keys.
|
boolean | contains(Object value) - Tests if some key maps into the specified value in this hashtable.
|
boolean | containsKey(Object key) - Tests if the specified object is a key in this hashtable.
|
Enumeration | elements() - Returns an enumeration of the values in this hashtable.
|
Object | get(Object key) - Returns the value to which the specified key is mapped in this hashtable.
|
boolean | isEmpty() - Tests if this hashtable maps no keys to values.
|
Enumeration | keys() - Returns an enumeration of the keys in this hashtable.
|
Object | put(Object key, Object value) - Maps the specified
key to the specified
value in this hashtable.
|
Object | remove(Object key) - Removes the key (and its corresponding value) from this
hashtable.
|
int | size() - Returns the number of keys in this hashtable.
|
String | toString() - Returns a rather long string representation of this hashtable.

Hashtable
public Hashtable()
Constructs a new, empty hashtable with a default capacity and load
factor.
Hashtable
public Hashtable(int initialCapacity)
Constructs a new, empty hashtable with the specified initial capacity
and default load factor.
Hashtable
public Hashtable(int initialCapacity,
float loadFactor)
Constructs a new, empty hashtable with the specified initial
capacity and the specified load factor.
clear
public void clear()
Clears this hashtable so that it contains no keys.
contains
public boolean contains(Object value)
Tests if some key maps into the specified value in this hashtable.
This operation is more expensive than the containsKey
method.
containsKey
public boolean containsKey(Object key)
Tests if the specified object is a key in this hashtable.
elements
public Enumeration elements()
Returns an enumeration of the values in this hashtable.
Use the Enumeration methods on the returned object to fetch the elements
sequentially.
get
public Object get(Object key)
Returns the value to which the specified key is mapped in this hashtable.
isEmpty
public boolean isEmpty()
Tests if this hashtable maps no keys to values.
keys
public Enumeration keys()
Returns an enumeration of the keys in this hashtable.
put
public Object put(Object key,
Object value)
Maps the specified
key
to the specified
value
in this hashtable. Neither the key nor the
value can be
null
.
The value can be retrieved by calling the
get
method
with a key that is equal to the original key.
remove
public Object remove(Object key)
Removes the key (and its corresponding value) from this
hashtable. This method does nothing if the key is not in the hashtable.
size
public int size()
Returns the number of keys in this hashtable.
toString
public String toString()
Returns a rather long string representation of this hashtable.
Handy for debugging - leave it here!!!
