SymbolHash (Xerces2 Implementation)

java.lang.Object
- org.apache.xerces.util.SymbolHash

```
public class SymbolHash
extends java.lang.Object
```
This class is an unsynchronized hash table primary used for String to Object mapping.
The hash code uses the same algorithm as SymbolTable class.

- Field Detail
  - fTableSize
```
protected int fTableSize
```
    Default table size.
  - fBuckets
```
protected SymbolHash.Entry[] fBuckets
```
    Buckets.
  - fNum
```
protected int fNum
```
    Number of elements.
- Constructor Detail
  - SymbolHash
```
public SymbolHash()
```
    Constructs a key table with the default size.
  - SymbolHash
```
public SymbolHash(int size)
```
    Constructs a key table with a given size.
    
    Parameters:
    
    size - the size of the key table.
- Method Detail
  - put
```
public void put(java.lang.Object key,
                java.lang.Object value)
```
    Adds the key/value mapping to the key table. If the key already exists, the previous value associated with this key is overwritten by the new value.
    
    Parameters:
    
    key -
    
    value -
  - get
```
public java.lang.Object get(java.lang.Object key)
```
    Get the value associated with the given key.
    
    Parameters:
    
    key -
    
    Returns:
    
    the value associated with the given key.
  - getLength
```
public int getLength()
```
    Get the number of key/value pairs stored in this table.
    
    Returns:
    
    the number of key/value pairs stored in this table.
  - getValues
```
public int getValues(java.lang.Object[] elements,
                     int from)
```
    Add all values to the given array. The array must have enough entry.
    
    Parameters:
    
    elements - the array to store the elements
    
    from - where to start store element in the array
    
    Returns:
    
    number of elements copied to the array
  - getEntries
```
public java.lang.Object[] getEntries()
```
    Return key/value pairs of all entries in the map
  - makeClone
```
public SymbolHash makeClone()
```
    Make a clone of this object.
  - clear
```
public void clear()
```
    Remove all key/value assocaition. This tries to save a bit of GC'ing by at least keeping the fBuckets array around.
  - search
```
protected SymbolHash.Entry search(java.lang.Object key,
                                  int bucket)
```
