详细描述

This exception is thrown when parse errors are encountered.

You can explicitly create objects of this exception type by calling the method generateParseException in the generated parser.

You can modify this class to customize your error reporting mechanisms so long as you retain the fields.

构造及析构函数说明

◆ ParseException() [1/3]

vhdl::parser::ParseException::ParseException	(	Token	currentTokenVal,
		int **	expectedTokenSequencesVal,
		JJString *	tokenImageVal
	)

This constructor is used by the method "generateParseException" in the generated parser.

Calling this constructor generates a new object of this type with the fields "currentToken", "expectedTokenSequences", and "tokenImage" set.

◆ ParseException() [2/3]

vhdl::parser::ParseException::ParseException ( )

The following constructors are for use by you for whatever purpose you can think of.

Constructing the exception in this manner makes the exception behave in the normal way - i.e., as documented in the class "Throwable". The fields "errorToken", "expectedTokenSequences", and "tokenImage" do not contain relevant information. The JavaCC generated code does not use these constructors.

◆ ParseException() [3/3]

vhdl::parser::ParseException::ParseException ( const JJString & message )

Constructor with message.

成员函数说明

◆ add_escapes()

JJString vhdl::parser::ParseException::add_escapes ( const JJString & str )

private

Used to convert raw characters to their escaped version when these raw version cannot be used as part of an ASCII string literal.

◆ initialise()

JJString vhdl::parser::ParseException::initialise	(	Token	currentToken,
		int **	expectedTokenSequences,
		JJString *	tokenImage
	)

private

It uses "currentToken" and "expectedTokenSequences" to generate a parse error message and returns it.

If this object has been created due to a parse error, and you do not catch it (it gets thrown from the parser) the correct error message gets displayed.

类成员变量说明

◆ currentToken

Token vhdl::parser::ParseException::currentToken

This is the last token that has been consumed successfully.

If this object has been created due to a parse error, the token followng this token will (therefore) be the first error token.

在文件 ParseException.h 第 56 行定义.

◆ expectedTokenSequences

int** vhdl::parser::ParseException::expectedTokenSequences

Each entry in this array is an array of integers.

Each array of integers represents a sequence of tokens (by their ordinal values) that is expected at this point of the parse.

在文件 ParseException.h 第 63 行定义.

◆ tokenImage

JJString* vhdl::parser::ParseException::tokenImage

This is a reference to the "tokenImage" array of the generated parser within which the parse error occurred.

This array is defined in the generated ...Constants class.
