class Input
Declaration
class Input : public IO { /* full declaration omitted */ };Description
The Input class is used to parse a yaml document into in-memory structs and vectors. It works by using YAMLParser to do a syntax parse of the entire yaml document, then the Input class builds a graph of HNodes which wraps each yaml Node. The extra layer is buffering. The low level yaml parser only lets you look at each node once. The buffering layer lets you search and interate multiple times. This is necessary because the mapRequired() method calls may not be in the same order as the keys in the document.
