public class StringCache
extends java.lang.Object

Implementation of a cache of strings

Constructor Summary

StringCache()
Constructs an empty IntHashMap with the default initial capacity (16) and the default load factor (0.75).

Method Summary

void	clear() Removes all mappings from this map.
java.lang.String	get(char[] chars) Returns the value to which the specified key is mapped in this identity hash map, or null if the map contains no mapping for this key.
java.lang.String	get(char[] chars, int offset, int length) Returns the value to which the specified key is mapped in this identity hash map, or null if the map contains no mapping for this key.
boolean	isEmpty() Returns true if this map contains no key-value mappings.

Constructor Detail

StringCache

public StringCache()

Constructs an empty IntHashMap with the default initial capacity (16) and the default load factor (0.75).

Method Detail

size

public int size()

Returns the number of key-value mappings in this map.

Returns:

the number of key-value mappings in this map.

isEmpty

public boolean isEmpty()

Returns true if this map contains no key-value mappings.

Returns:

true if this map contains no key-value mappings.

get

public java.lang.String get(char[] chars)

Returns the value to which the specified key is mapped in this identity hash map, or null if the map contains no mapping for this key. A return value of null does not necessarily indicate that the map contains no mapping for the key; it is also possible that the map explicitly maps the key to null. The containsKey method may be used to distinguish these two cases.

Parameters:

key - the key whose associated value is to be returned.

Returns:

the value to which this map maps the specified key, or null if the map contains no mapping for this key.

#put(Object, Object)

get

public java.lang.String get(char[] chars,
                            int offset,
                            int length)

Returns the value to which the specified key is mapped in this identity hash map, or null if the map contains no mapping for this key. A return value of null does not necessarily indicate that the map contains no mapping for the key; it is also possible that the map explicitly maps the key to null. The containsKey method may be used to distinguish these two cases.

Parameters:

key - the key whose associated value is to be returned.

Returns:

the value to which this map maps the specified key, or null if the map contains no mapping for this key.

#put(Object, Object)

clear

public void clear()

Removes all mappings from this map.
