构造及析构函数说明

◆ Token() [1/3]

vhdl::parser::Token::Token ( )

No-argument constructor

◆ Token() [2/3]

vhdl::parser::Token::Token ( int kind )

Constructs a new token for the specified Image.

◆ Token() [3/3]

vhdl::parser::Token::Token	(	int	kind,
		const JJString &	image
	)

Constructs a new token for the specified Image and Kind.

◆ ~Token()

virtual vhdl::parser::Token::~Token ( )

virtual

成员函数说明

◆ getValue()

void* vhdl::parser::Token::getValue ( )

An optional attribute value of the Token.

Tokens which are not used as syntactic sugar will often contain meaningful values that will be used later on by the compiler or interpreter. This attribute value is often different from the image. Any subclass of Token that actually wants to return a non-NULL value can override this method as appropriate.

◆ newToken() [1/2]

static Token* vhdl::parser::Token::newToken ( int ofKind )

static

◆ newToken() [2/2]

static Token* vhdl::parser::Token::newToken	(	int	ofKind,
		const JJString &	image
	)

static

Returns a new Token void *, by default.

However, if you want, you can create and return subclass objects based on the value of ofKind. Simply add the cases to the switch for all those special cases. For example, if you have a subclass of Token called IDToken that you want to create if ofKind is ID, simply add something like :

case MyParserConstants.ID : return new IDToken(ofKind, image);

to the following switch statement. Then you can cast matchedToken variable to the appropriate type and use sit in your lexical actions.

◆ toString()

const JJString& vhdl::parser::Token::toString ( )

Returns the image.

类成员变量说明

◆ beginColumn

int vhdl::parser::Token::beginColumn

The column number of the first character of this Token.

在文件 Token.h 第 30 行定义.

被这些函数引用 vhdl::parser::ErrorHandler::handleParseError() , 以及 vhdl::parser::ErrorHandler::handleUnexpectedToken().

◆ beginLine

int vhdl::parser::Token::beginLine

The line number of the first character of this Token.

在文件 Token.h 第 28 行定义.

被这些函数引用 vhdl::parser::VhdlErrorHandler::handleParseError(), vhdl::parser::ErrorHandler::handleParseError(), vhdl::parser::VhdlErrorHandler::handleUnexpectedToken() , 以及 vhdl::parser::ErrorHandler::handleUnexpectedToken().

◆ endColumn

int vhdl::parser::Token::endColumn

The column number of the last character of this Token.

在文件 Token.h 第 34 行定义.

◆ endLine

int vhdl::parser::Token::endLine

The line number of the last character of this Token.

在文件 Token.h 第 32 行定义.

◆ image

JJString vhdl::parser::Token::image

The string image of the token.

在文件 Token.h 第 39 行定义.

被这些函数引用 vhdl::parser::VhdlErrorHandler::handleParseError(), vhdl::parser::ErrorHandler::handleParseError(), vhdl::parser::VhdlErrorHandler::handleUnexpectedToken() , 以及 vhdl::parser::ErrorHandler::handleUnexpectedToken().

◆ kind

int vhdl::parser::Token::kind

An integer that describes the kind of this token.

This numbering system is determined by JavaCCParser, and a table of these numbers is stored in the file ...Constants.java.

在文件 Token.h 第 25 行定义.

被这些函数引用 VHDLOutlineParser::error_skipto().

◆ next

Token* vhdl::parser::Token::next

A reference to the next regular (non-special) token from the input stream.

If this is the last token from the input stream, or if the token manager has not read tokens beyond this one, this field is set to NULL. This is true only if this token is also a regular token. Otherwise, see below for a description of the contents of this field.

在文件 Token.h 第 49 行定义.

◆ specialToken

Token* vhdl::parser::Token::specialToken

This field is used to access special tokens that occur prior to this token, but after the immediately preceding regular (non-special) token.

If there are no such special tokens, this field is set to NULL. When there are more than one such special token, this field refers to the last of these special tokens, which in turn refers to the next previous special token through its specialToken field, and so on until the first special token (whose specialToke_ field is NULL). The next fields of special tokens refer to other special tokens that immediately follow it (without an intervening regular token). If there is no such token, this field is NULL.
