Method Detail

fillInvertedMap

public void fillInvertedMap(Map<vectorObject,key> map)

fill this with the values in map by switching key and value

Parameters:

map -

getOne

public vectorObject getOne(Object key,
                  int i)

get the value for key

Parameters:

key - the search key

i - the index in the vecor matching key; if <0 count from the back of the vector

Returns:

the matching vectorObject; null if the key does not exist or i is out of range

getIndex

public int getIndex(key key,
           vectorObject singleObject)

get the index of singleObject in the vector of key

Parameters:

key - the key of the vector

singleObject - the object to search

Returns:

-2: no such key; -1: no value in key; else the index in the vexctor of key

size

public int size(key key)

get the size of the vector for key

Parameters:

key - the key of the vector

Returns:

the size of the vector for key, 0 if no key exists

putOne

public void putOne(key key,
          vectorObject val)

put the value for key, ensuring uniqueness

Parameters:

key - the key of the vector

val - the vector element

appendUnique

public void appendUnique(key key,
                Vector<vectorObject> vVal)

append a map, ensuring uniqueness

Parameters:

key - the key of the vector

vVal - the vector of elements

appendUnique

public void appendUnique(VectorMap<key,vectorObject> map)

append a VectorMap, ensuring uniqueness

Parameters:

map - the map to add

getAllValues

public Vector<vectorObject> getAllValues()

get all values as one big vector, multiple entries are retained (see ContainerUtil.unify())

Returns:

a vector of all values, null if empty

getInvertedMap

public Map<vectorObject,key> getInvertedMap()

get an inverted map that uses all entries a s keys and vice versa
note that the behavior is undefined in case of multiple identical values

Returns:

an inverted map

removeOne

public void removeOne(key key,
             vectorObject val)

remove the value for key,also remove key if the vector is empty

Parameters:

key - the key of the vector

val - the vector element

setOne

public void setOne(key key,
          vectorObject newObj,
          vectorObject oldObj)

replace the value for key, add if oldObj==null or is not there

Parameters:

key - the key of the vector

newObj - the new object to set

oldObj - the old object to replace

setOne

public void setOne(key key,
          vectorObject newObj,
          int pos)

insert the value for keyat position pos

Parameters:

key - the key of the vector

newObj - the new object to set

pos - the index in the vector, may be <0 to count from the end

Throws:

IllegalArgumentException - if pos is negative and abs(pos)>size()

isUnique

public boolean isUnique()

Getter for bUnique attribute.

Returns:

the bUnique

setUnique

public void setUnique(boolean bUnique)

Setter for bUnique attribute.

Parameters:

bUnique - the bUnique to set
