DefaultsList

public DefaultsList()

Creates a DefaultsList.

Method Details

add

public void add(Object key,
 Object value)

Adds a key/value pair to the defaults list. This implementation defers to add(Object, Object, boolean) with enableChecking set to true.

Parameters:

key - the key that will be used to query UIDefaults

value - the value associated with the key

Throws:

NullPointerException - if key is null

IllegalArgumentException - if value is a type that should be a UIResource but is not. For instance, passing in a Border that is not a UIResource will cause an exception. This checking must be enabled.

add

public void add(Object key,
 Object value,
 boolean enableChecking)

Adds a key/value pair to the defaults list. A pair with a null value is treated specially. A null-value pair is never added to the list and, furthermore, if a key/value pair exists in this list with the same key as the newly added one, it is removed.

Parameters:

key - the key that will be used to query UIDefaults

value - the value associated with the key

enableChecking - if true then the value is checked to ensure that it is a UIResource, if appropriate

Throws:

NullPointerException - if key is null

IllegalArgumentException - if value is a type that should be a UIResource but is not. For instance, passing in a Border that is not a UIResource will cause an exception. This checking must be enabled.

asUIResource

private static <T> T asUIResource(T value,
 String message)

toArray

public Object[] toArray()

Gets a copy of this list as an array.

Returns:

an array containing all of the key/value pairs added to this list
