Description copied from interface: DataHolder

Get key if it exists or compute using supplier

Method used by DataKey classes to access data.

NOTE: MutableDataHolders will compute an absent key and add it to its dataSet. DataHolders will return computed value but not change contained dataSet because they are immutable. So value will be computed every time it is requested.

Specified by:

getOrCompute in interface DataHolder

Overrides:

getOrCompute in class DataSet

Parameters:

key - data key

factory - factory taking this data holder and computing/providing default value

Returns:

object value for the key
