Method Detail

size

int size()

Returns:

the number of associations in this ILcdAssocSet.

keys

java.util.Enumeration keys()

Returns:

an enumeration of the keys.

elements

java.util.Enumeration elements()

Returns:

an enumeration of the values.

put

void put(java.lang.Object aKey,
         java.lang.Object aValue)

Adds an association having with a given value and a given key to this set. If an association with the same key already exists, it will be replaced by the given one.

Parameters:

aKey - the key.

aValue - the value.

getAssocs

ILcdAssoc[] getAssocs()

Returns:

the associations as an array of ILcdAssoc objects.

setAssocs

void setAssocs(ILcdAssoc[] aAssocArray)

Sets the associations as an array of ILcdAssoc objects.

add

void add(ILcdAssoc aAssoc)

Adds an association to this set. If an association with the same key already exists, it will be replaced by the given one.

Parameters:

aAssoc - the association to be added.

remove

java.lang.Object remove(java.lang.Object aKey)

Removes the association with the given key. If the given association does not exist, no action will be performed.

Parameters:

aKey - the key of the association to be removed.

Returns:

the value corresponding to the key, or null if the key does not exist.

removeAll

void removeAll()

Removes all the associations.

hasValue

boolean hasValue(java.lang.Object aKey)

Tests if the set has a value for the given key.

Parameters:

aKey - the key to look up.

Returns:

true if the given key has a corresponding value, false otherwise.

getValue

java.lang.Object getValue(java.lang.Object aKey)

Gets the value associated with the given key.

Parameters:

aKey - the key to look up.

Returns:

the value corresponding to the key, or null if the key does not exist.

cloneAsILcdAssocSet

ILcdAssocSet cloneAsILcdAssocSet()

Returns:

a clone of this ILcdAssocSet.
