Méthode	Description
GetServiceForFileName ( string filename ) : IParsingService	Finds the language service associated with the longest matching registered file extension. Returns null if there is no registered language service for the filename's extension.
Parse ( this parser, Stream stream, string fileName, ParsingMode inputType = null, IMessageSink msgs = null, bool preserveComments = true ) : IListSource	Parses a Stream.
Parse ( this parser, UString input, IMessageSink msgs = null, ParsingMode inputType = null, bool preserveComments = true ) : IListSource	Parses a string by invoking IParsingService.Parse(ICharSource, string, IMessageSink, ParsingMode, bool) using an empty string as the file name.
ParseFile ( this parser, string fileName, IMessageSink msgs = null, ParsingMode inputType = null, bool preserveComments = true ) : IListSource	Opens the specified file and parses it.
ParseSingle ( this parser, ICharSource text, string fileName, IMessageSink msgs = null, ParsingMode inputType = null, bool preserveComments = true ) : LNode	Parses a string and expects exactly one output.
ParseSingle ( this parser, UString expr, IMessageSink msgs = null, ParsingMode inputType = null, bool preserveComments = true ) : LNode	Parses a string and expects exactly one output.
PushCurrent ( IParsingService newValue ) : PushedCurrent	Sets the current language service, returning a value suitable for use in a C# using statement, which will restore the old service.
Register ( IParsingService service, IEnumerable fileExtensions = null ) : int	Registers a parsing service. This method does not replace existing registrations.
SetDefault ( IParsingService newValue ) : SavedValue
Tokenize ( this parser, Stream stream, string fileName, IMessageSink msgs = null ) : ILexer	Parses a Stream.
Tokenize ( this parser, UString input, IMessageSink msgs = null ) : ILexer	Parses a string by invoking IParsingService.Tokenize(ICharSource, string, IMessageSink) using an empty string as the file name.
TokenizeFile ( this parser, string fileName, IMessageSink msgs = null ) : ILexer	Opens the specified file and tokenizes it.
Unregister ( IParsingService service, IEnumerable fileExtensions = null ) : int	Unregisters a language service. The service for a file extension is not removed unless the given service reference is equal to the registered service.

Method Details

GetServiceForFileName() public static méthode

Finds the language service associated with the longest matching registered file extension.

Returns null if there is no registered language service for the filename's extension.

public static GetServiceForFileName ( string filename ) : IParsingService
filename	string
Résultat	IParsingService

Parse() public static méthode

Parses a Stream.

public static Parse ( this parser, Stream stream, string fileName, ParsingMode inputType = null, IMessageSink msgs = null, bool preserveComments = true ) : IListSource
parser	this
stream	Stream
fileName	string
inputType	ParsingMode
msgs	IMessageSink
preserveComments	bool
Résultat	IListSource

Parse() public static méthode

Parses a string by invoking IParsingService.Parse(ICharSource, string, IMessageSink, ParsingMode, bool) using an empty string as the file name.

public static Parse ( this parser, UString input, IMessageSink msgs = null, ParsingMode inputType = null, bool preserveComments = true ) : IListSource
parser	this
input	UString
msgs	IMessageSink
inputType	ParsingMode
preserveComments	bool
Résultat	IListSource

ParseFile() public static méthode

Opens the specified file and parses it.

public static ParseFile ( this parser, string fileName, IMessageSink msgs = null, ParsingMode inputType = null, bool preserveComments = true ) : IListSource
parser	this
fileName	string
msgs	IMessageSink
inputType	ParsingMode
preserveComments	bool
Résultat	IListSource

ParseSingle() public static méthode

Parses a string and expects exactly one output.

The output list was empty or contained multiple nodes.

public static ParseSingle ( this parser, ICharSource text, string fileName, IMessageSink msgs = null, ParsingMode inputType = null, bool preserveComments = true ) : LNode
parser	this
text	ICharSource
fileName	string
msgs	IMessageSink
inputType	ParsingMode
preserveComments	bool
Résultat	LNode

ParseSingle() public static méthode

Parses a string and expects exactly one output.

The output list was empty or contained multiple nodes.

public static ParseSingle ( this parser, UString expr, IMessageSink msgs = null, ParsingMode inputType = null, bool preserveComments = true ) : LNode
parser	this
expr	UString
msgs	IMessageSink
inputType	ParsingMode
preserveComments	bool
Résultat	LNode

PushCurrent() public static méthode

Sets the current language service, returning a value suitable for use in a C# using statement, which will restore the old service.

public static PushCurrent ( IParsingService newValue ) : PushedCurrent
newValue	IParsingService	new value of Current
Résultat	PushedCurrent

Register() public static méthode

Registers a parsing service.

This method does not replace existing registrations.

public static Register ( IParsingService service, IEnumerable fileExtensions = null ) : int
service	IParsingService	Service to register.
fileExtensions	IEnumerable	File extensions affected (null to use the service's own list)
Résultat	int

SetDefault() public static méthode

public static SetDefault ( IParsingService newValue ) : SavedValue
newValue	IParsingService
Résultat	SavedValue

Tokenize() public static méthode

Parses a Stream.

public static Tokenize ( this parser, Stream stream, string fileName, IMessageSink msgs = null ) : ILexer
parser	this
stream	Stream
fileName	string
msgs	IMessageSink
Résultat	ILexer

Tokenize() public static méthode

Parses a string by invoking IParsingService.Tokenize(ICharSource, string, IMessageSink) using an empty string as the file name.

public static Tokenize ( this parser, UString input, IMessageSink msgs = null ) : ILexer
parser	this
input	UString
msgs	IMessageSink
