| ParseException | | public class ParseException extends Exception (Code) | | 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.
|
| Field Summary | |
| public Token | currentToken
This is the last token that has been consumed successfully. | | protected String | eol
The end of line string for this machine. | | public int[][] | expectedTokenSequences
Each entry in this array is an array of integers. | | protected boolean | specialConstructor
This variable determines which constructor was used to create this object
and thereby affects the semantics of the "getMessage" method (see below). | | public String[] | tokenImage
This is a reference to the "tokenImage" array of the generated parser
within which the parse error occurred. |
| Constructor Summary | |
| public | ParseException(Token currentTokenVal, int[][] expectedTokenSequencesVal, String[] tokenImageVal)
This constructor is used by the method "generateParseException" in the
generated parser. | | public | ParseException()
The following constructors are for use by you for whatever purpose you can
think of. | | public | ParseException(String message)
|
| Method Summary | |
| protected String | add_escapes(String str)
Used to convert raw characters to their escaped version when these raw
version cannot be used as part of an ASCII string literal. | | public String | getMessage()
This method has the standard behavior when this object has been created
using the standard constructors. |
| currentToken | | public Token currentToken(Code) | | 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.
|
| eol | | protected String eol(Code) | | The end of line string for this machine.
|
| expectedTokenSequences | | public int[][] expectedTokenSequences(Code) | | 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.
|
| specialConstructor | | protected boolean specialConstructor(Code) | | This variable determines which constructor was used to create this object
and thereby affects the semantics of the "getMessage" method (see below).
|
| tokenImage | | public String[] tokenImage(Code) | | 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 interface.
|
| ParseException | | public ParseException(Token currentTokenVal, int[][] expectedTokenSequencesVal, String[] tokenImageVal)(Code) | | 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()(Code) | | 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.
|
| add_escapes | | protected String add_escapes(String str)(Code) | | Used to convert raw characters to their escaped version when these raw
version cannot be used as part of an ASCII string literal.
|
| getMessage | | public String getMessage()(Code) | | 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.
