set

public <T> void set(PropertyKey<T> property,
                    T value)

Associates the specified value with the specified property key. If the properties previously contained a mapping for the property key, the old value is replaced by the specified value.

Type Parameters:

T - the type of the value

Parameters:

property - the property key with which the specified value is to be associated

value - the value to be associated with the specified property key

set

public <T> void set(PropertyListKey<T> property,
                    List<T> value)

Associates the specified list with the specified property key. If the properties previously contained a mapping for the property key, the old value is replaced by the specified list.

Type Parameters:

T - the type of elements in the list

Parameters:

property - the property key with which the specified list is to be associated

value - the list to be associated with the specified property key

set

public <K,V> void set(PropertyMapKey<K,V> property,
                      Map<K,V> value)

Associates the specified map with the specified property key. If the properties previously contained a mapping for the property key, the old value is replaced by the specified map.

Type Parameters:

K - the type of keys maintained by the map

V - the type of mapped values

Parameters:

property - the property key with which the specified map is to be associated

value - the map to be associated with the specified property key

addListItem

public <T> void addListItem(PropertyListKey<T> property,
                            T value)

Append the value to the list to which the specified property key is mapped. If this properties contains no mapping for the property key, the value append to a new list witch is associate the the specified property key.

Type Parameters:

T - the type of elements in the list

Parameters:

property - the property key whose associated list is to be added

value - the value to be appended to list

putMapEntry

public <K,V> void putMapEntry(PropertyMapKey<K,V> property,
                              K key,
                              V value)

Insert the value to the map to which the specified property key is mapped. If this properties contains no mapping for the property key, the value insert to a new map witch is associate the the specified property key.

Type Parameters:

K - the type of keys maintained by the map

V - the type of mapped values

Parameters:

property - the property key whose associated list is to be added

value - the value to be appended to list
