Method Detail

get

public Object get(Object key)

Retrieves a value from the cache. If the value is not cached, this method retrieves the uncached value and inserts it in the cache store.

Specified by:

get in interface Cache

Parameters:

key - an object whose associated value is cached.

Returns:

the value to which key is associated.

getValueAt

public Object getValueAt(Object row,
                         int column)

Retrieves the cached value for node at index column. If the value is not cached, this method retrieves the uncached value and inserts it in the cache store.

Specified by:

getValueAt in interface TreeTableCache

Parameters:

row - the node to consider

column - the cell's column index

Returns:

the cached value

isValueCached

public boolean isValueCached(Object key)

Determines whether the value specificed by key is cached.

Specified by:

isValueCached in interface Cache

Parameters:

key - an object whose associated value is cached.

Returns:

true if the value is cached.

isValueCached

public boolean isValueCached(Object key,
                             int column)

Determines whether the value for node at index column exists in the cache.

Specified by:

isValueCached in interface TreeTableCache

Parameters:

key - the node to consider

column - the cell's column index

Returns:

true if the value is cached

put

public void put(Object key,
                Object value)

Inserts a value in the cache store.

Specified by:

put in interface Cache

Parameters:

key - an object whose associated value is cached.

value - the value to cache.

remove

public Object remove(Object key)

Removes a value from the cache store.

Specified by:

remove in interface Cache

Parameters:

key - an object whose associated value is cached.

removeAll

public void removeAll()

Clears the cache.

Specified by:

removeAll in interface Cache

setCacheTreeTableModel

public void setCacheTreeTableModel(CacheableTreeTableModel m)

Assigns a CacheableTreeTableModel that will be used to retrieve the uncached values.

Specified by:

setCacheTreeTableModel in interface TreeTableCache

Parameters:

m - the cacheable treetable model that will be used as the source.
