the cached value

isValueCached

boolean isValueCached(Object node,

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

Parameters:

node - the node to consider

column - the cell's column index

Returns:

true if the value is cached

setCacheTreeTableModel

void setCacheTreeTableModel(CacheableTreeTableModel model)

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