Purpose

Provide pretty-printing implementation for balxml_formatter .

Classes

• balxml::Formatter_PrettyImplState: state of formatter state machine
• balxml::Formatter_PrettyImplStateId: labels for formatter state
• balxml::Formatter_PrettyImplUtil: actions of formatter state machine

Description

This private, subordinate component to balxml_formatter provides an in-core value semantic attribute class, balxml::Formatter_PrettyImplState, and a utility struct, balxml::Formatter_PrettyImplUtil, that implements XML pretty-printing operations using the state value type. These two classes work in conjunction to implement a state machine for pretty-printing an XML document given a sequence of tokens to emit. The class balxml::Formatter_PrettyImplStateId enumerates the set of labels for distinct states of balxml::Formatter_PrettyImplState, upon which most control-flow decisions of balxml::Formatter_PrettyImplUtil are based.
