Method Detail
-
getNoEntryKey
short getNoEntryKey()
Returns the value that will be returned fromget(short)orput(short, float)if no entry exists for a given key. The default value is generally zero, but can be configured during construction of the collection.- Returns:
- the value that represents a null key in this collection.
-
getNoEntryValue
float getNoEntryValue()
Returns the value that will be returned fromget(short)orput(short, float)if no entry exists for a given key. The default value is generally zero, but can be configured during construction of the collection.- Returns:
- the value that represents a null value in this collection.
-
put
float put(short key, float value)Inserts a key/value pair into the map.- Returns:
- the previous value associated with key, or the "no entry" value
if none was found (see
getNoEntryValue()).
-
putIfAbsent
float putIfAbsent(short key, float value)Inserts a key/value pair into the map if the specified key is not already associated with a 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.Float> 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(TShortFloatMap 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
float get(short key)
Retrieves the value for key.- 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
float remove(short key)
Deletes a key/value pair from the map.- Parameters:
key- anshortvalue- Returns:
- the previous value associated with key, or the "no entry" value
if none was found (see
getNoEntryValue()).
-
size
int size()
Returns an int value that is the number of elements in the map.- Returns:
- an int value that is the number of elements in the map.
-
keySet
TShortSet keySet()
Returns the keys of the map as a TShortSet- Returns:
- the keys of the map as a TShortSet
-
keys
short[] keys()
Returns the keys of the map as an array of short values.- Returns:
- the keys of the map as an array of short values.
-
keys
short[] keys(short[] array)
Returns the keys of the map.- Parameters:
array- the array into which the elements of the list are to be stored, if it is big enough; otherwise, a new array of the same type is allocated for this purpose.- Returns:
- the keys of the map as an array.
-
valueCollection
TFloatCollection valueCollection()
Returns the values of the map as a TFloatCollection- Returns:
- the values of the map as a TFloatCollection
-
values
float[] values()
Returns the values of the map as an array of #e# values.- Returns:
- the values of the map as an array of #e# values.
-
values
float[] values(float[] array)
Returns the values of the map using an existing array.- Parameters:
array- the array into which the elements of the list are to be stored, if it is big enough; otherwise, a new array of the same type is allocated for this purpose.- Returns:
- the values of the map as an array of #e# values.
-
containsValue
boolean containsValue(float val)
Checks for the presence of val in the values of the map.
-
containsKey
boolean containsKey(short key)
Checks for the present of key in the keys of the map.
-
iterator
TShortFloatIterator iterator()
- Returns:
- a TShortFloatIterator with access to this map's keys and values
-
forEachKey
boolean forEachKey(TShortProcedure procedure)
Executes procedure for each key in the map.- Parameters:
procedure- aTShortProcedurevalue- Returns:
- false if the loop over the keys terminated because the procedure returned false for some key.
-
forEachValue
boolean forEachValue(TFloatProcedure procedure)
Executes procedure for each value in the map.- Parameters:
procedure- aT#F#Procedurevalue- Returns:
- false if the loop over the values terminated because the procedure returned false for some value.
-
forEachEntry
boolean forEachEntry(TShortFloatProcedure procedure)
Executes procedure for each key/value entry in the map.- Parameters:
procedure- aTOShortFloatProcedurevalue- Returns:
- false if the loop over the entries terminated because the procedure returned false for some entry.
-
transformValues
void transformValues(TFloatFunction function)
Transform the values in this map using function.- Parameters:
function- aTFloatFunctionvalue
-
retainEntries
boolean retainEntries(TShortFloatProcedure procedure)
Retains only those entries in the map for which the procedure returns a true value.- Parameters:
procedure- determines which entries to keep- Returns:
- true if the map was modified.
-
increment
boolean increment(short key)
Increments the primitive value mapped to key by 1- Parameters:
key- the key of the value to increment- Returns:
- true if a mapping was found and modified.
-
adjustValue
boolean adjustValue(short key, float amount)Adjusts the primitive value mapped to key.- Parameters:
key- the key of the value to incrementamount- the amount to adjust the value by.- Returns:
- true if a mapping was found and modified.
