class DBElement (source)
Class representing the atomic component of each node.
Can be either an aggregated value (A:x), or a key-value pair (P:(x,y)). The discrimination happens by means of the boolean
Field
isAgg: that goes true if the content is an aggregated value.
The DBElement stores the values of pairs and aggregated values in the form of Strings (i.e. they are always stored as non-parsed, hence not in their actual types). Parsing to the actual type is performed every time we need to execute some operation (e.g. comparisons, etc) with the actual content of the DBElement.
