Classes
class	State_Constants
	Represents constants used in the State machine. This is needed in a separate class because 1) C# requires constants to be defined inside a class or struct and 2) the constant is needed across multiple classes. More...
interface	IStateContext
	Represents the context as passed to each state class. More...
interface	IStateBehavior
	Represents a class that implements one state of the state machine. More...
class	State_NormalText
	Represents normal text behavior. More...
class	State_DoubleQuotedText
	Represents being inside a double-quote string where filtering is essentially turned off until the end of the string is reached. More...
class	State_SingleQuotedText
	Represents being inside a single-quoted string where filtering is effectively turned off until the end of the string is reached. More...
class	State_EscapedDoubleQuoteText
	Represents being in an escaped character sequence inside a double- quoted string. We don't do anything with the escaped character other than output it. Handling escaped characters allows us to more accurately detect the end of the string. More...
class	State_EscapedSingleQuoteText
	Represents being in an escaped character sequence inside a single- quoted string. We don't do anything with the escaped character other than output it. Handling escaped characters allows us to more accurately detect the end of the string. More...
class	State_StartComment
	Represents the possible start of a line or block comment. More...
class	State_LineComment
	Represents being in a line comment. More...
class	State_BlockComment
	Represents being in a block comment. More...
class	State_EndBlockComment
	Represents possibly being at the end of a block comment. More...
class	State_Done
	Represents being done with input. More...
class	State_Factory
	Class factory for generating the state class instances. More...
class	StateContext_Class
	Represents the state machine. This maintains the context in which the state machine runs. More...

Namespaces
namespace	DesignPatternExamples_csharp
	The namespace containing all Design Pattern Examples implemented in C#.

Enumerations
enum	CurrentState {   Initial , NormalText , DoubleQuotedText , SingleQuotedText ,   EscapedDoubleQuoteText , EscapedSingleQuoteText , StartComment , LineComment ,   BlockComment , EndBlockComment , Done }
	Represents the current state of the state machine. More...
