C# 클래스 CK.Core.StringMatcher

This class supports "Match and Forward" pattern. On a failed match, the SetError method sets the ErrorMessage. On a successful match, the StartIndex is updated by a call to Forward so that the Head is positioned after the match (and any existing error is cleared).

공개 메소드들

메소드	설명
BackwardSetError ( int savedStartIndex, object expectedMessage = null, [ callerName = null ) : bool	Moves back the head at a previously index and sets an error. The message starts with the caller's method name.
Forward ( int charCount ) : bool	Increments the StartIndex (and decrements Length) with the specified character count and clears any existing error.
MatchChar ( char c ) : bool	Matches an exact single character. If match fails, SetError is called.
MatchWhiteSpaces ( int minCount = 1 ) : bool	Matches a sequence of white spaces.
SetError ( object expectedMessage = null, [ callerName = null ) : bool	Sets an error. The message starts with the caller's method name.
SetSuccess ( ) : bool	Clears any error and returns true.
StringMatcher ( string text, int startIndex ) : System	Initializes a new instance of the StringMatcher class.
StringMatcher ( string text, int startIndex, int length ) : System	Initializes a new instance of the StringMatcher class on a substring.
ToString ( ) : string	Overridden to return a detailed string with ErrorMessage (if any), the Head character, StartIndex position and whole Text.
TryMatchChar ( char c ) : bool	Attempts to match an exact single character.
TryMatchDoubleValue ( ) : bool	Matches a double without getting its value nor setting an error if match fails. This uses RegexDouble.
TryMatchJSONQuotedString ( bool allowNull = false ) : bool	Matches a quoted string without extracting its content.
TryMatchJSONQuotedString ( string &content, bool allowNull = false ) : bool	Matches a quoted string without setting an error if match fails.
TryMatchText ( string s, System.StringComparison comparisonType = StringComparison.OrdinalIgnoreCase ) : bool	Matches a string without setting an error if match fails.
UncheckedMove ( int delta ) : bool	Moves the head without any check and returns always true: typically called by successful TryMatch methods.

메소드 상세

BackwardSetError() 공개 메소드

Moves back the head at a previously index and sets an error. The message starts with the caller's method name.

public BackwardSetError ( int savedStartIndex, object expectedMessage = null, [ callerName = null ) : bool
savedStartIndex	int	Index to reset.
expectedMessage	object	/// Optional object. Its will be used to generate an "expected '...'" message. ///
callerName	[	Name of the caller (automatically injected by the compiler).
리턴	bool

Forward() 공개 메소드

Increments the StartIndex (and decrements Length) with the specified character count and clears any existing error.

public Forward ( int charCount ) : bool
charCount	int	The successfully matched character count. /// Must be positive and should not move head past the end of the substring.
리턴	bool

MatchChar() 공개 메소드

Matches an exact single character. If match fails, SetError is called.

public MatchChar ( char c ) : bool
c	char	The character that must match.

Matches a sequence of white spaces.

public MatchWhiteSpaces ( int minCount = 1 ) : bool
minCount	int	Minimal number of white spaces to match.
리턴	bool

SetError() 공개 메소드

Sets an error. The message starts with the caller's method name.

StringMatcher() 공개 메소드

Initializes a new instance of the StringMatcher class on a substring.

public StringMatcher ( string text, int startIndex, int length ) : System
