Method Detail

getNoEntryKey

short getNoEntryKey()

Returns:

the value that represents a null key in this collection.

getNoEntryValue

short getNoEntryValue()

Returns the value that will be returned from get(short) or put(short, short) if no entry exists for a given key. The default value is generally zero, but can be changed during construction of the collection.

Returns:

the value that represents a null value in this collection.

put

short put(short key,
          short value)

Inserts a key/value pair into the map.

Parameters:

key - an short value

value - an short value

Returns:

the previous value associated with key, or the "no entry" value if none was found (see getNoEntryValue()).

putIfAbsent

short putIfAbsent(short key,
                  short value)

Inserts a key/value pair into the map if the specified key is not already associated with a value.

Parameters:

key - an short value

value - an short value

Returns:

the previous value associated with key, or the "no entry" value if none was found (see getNoEntryValue()).

putAll

void putAll(java.util.Map<? extends java.lang.Short,? extends java.lang.Short> map)

Put all the entries from the given Map into this map.

Parameters:

map - The Map from which entries will be obtained to put into this map.

putAll

void putAll(TShortShortMap map)

Put all the entries from the given map into this map.

Parameters:

map - The map from which entries will be obtained to put into this map.

get

short get(short key)

Retrieves the value for key

Parameters:

key - an short value

Returns:

the previous value associated with key, or the "no entry" value if none was found (see getNoEntryValue()).

clear

void clear()

Empties the map.

isEmpty

boolean isEmpty()

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

Returns:

true if this map contains no key-value mappings

remove

short remove(short key)

Deletes a key/value pair from the map.

Parameters:

key - an short value
