- 所有已实现的接口:
Serializable
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 public fields.

ParseException
public ParseException(Token currentTokenVal, int[][] expectedTokenSequencesVal, String[] 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. The boolean flag "specialConstructor" is also set to true to indicate that this constructor was used to create this object. This constructor calls its super class with the empty string to force the "toString" method of parent class "Throwable" to print the error message in the form: ParseException: -
ParseException
public 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. -

getMessage
This method has the standard behavior when this object has been created using the standard constructors. Otherwise, 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), then this method is called during the printing of the final stack trace, and hence the correct error message gets displayed. -
