Pg::Explain::From - Base class for parsers of non-text explain formats.
It's internal class to wrap some work. It should be used by Pg::Explain, and not directly.
Function which parses actual plan, and constructs Pg::Explain::Node objects which represent it.
Returns Top node of query plan.
Simple function to let subclasses change the real keys that should be used when parsing structure.
This is (currently) useful only for XML parser.
Converts single node from structure obtained from source into Pg::Explain::Node class.
Recurses when necessary to get subnodes.
