public class AssociationListSelector

extends com.sas.util.selectors.IntegerIndexedSelector

A selector which handles collections which implement AssociationListInterface. This includes AssociationList. The key may be an integer, in which case the selected item is the value alist.get(integerKey()). if the key is not an integer, the selected item is the value alist.get(get())

Constructor Detail

AssociationListSelector

public AssociationListSelector()

Default constructor.

AssociationListSelector

public AssociationListSelector(Object collection,
                               Object key)

Construct an AssociationListSelector for a AssociationList and key

Parameters:

collection - The collection from which elements are selected

key - The key, which should be an Integer or some value from which an integer can be selected

Method Detail

getExtendedBeanInfo

public static ExtendedBeanInfo getExtendedBeanInfo()

getValue

public Object getValue(int index)

Get the value of the i^th element from the association list.

Overrides:

getValue in class com.sas.util.selectors.IntegerIndexedSelector

Parameters:

i - the item index

Returns:

the value at aList.get(index)

getValue

public Object getValue(Object key)

Get the value from the association list, based on the key. If the key represents an integer, use getValue(int), else use associationList.get(Object)

Overrides:

getValue in class com.sas.util.selectors.IntegerIndexedSelector

Parameters:

key - The key for the item

Returns:

the corresponding value from the association list.

keyAsInteger

public int keyAsInteger(Object value)

Find the integer key associated with the value

Overrides:

keyAsInteger in class com.sas.util.selectors.IntegerIndexedSelector

Parameters:

value - a value within the association list.

Returns:

the integer index where the value was found.

See Also:

StaticOrderedCollectionInterface.getIndex(Object, int)

getKey

public Object getKey(Object value)

Return the key that corresponds to a value

Overrides:

getKey in class BaseSelector

Following copied from class: com.sas.util.selectors.BaseSelector

Returns:

the selection key.

computeIntegerKey

public static int computeIntegerKey(Object key)

Convert a key/value into an integer.

Parameters:

key - some value

Returns:

int the integer value of the key.

Throws:

IllegalArgumentException - if the key cannot be interpreted as an integer.
