public class ParseException
extends Exception

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
 TokencurrentToken
          This is the last token that has been consumed successfully.
 int[][]expectedTokenSequences
          Each entry in this array is an array of integers.
 String[]tokenImage
          This is a reference to the "tokenImage" array of the generated
parser within which the parse error occurred.

Constructor Summary
ParseException(Token currentTokenVal, int[][] expectedTokenSequencesVal, String[] tokenImageVal)
          This constructor is used by the method "generateParseException"
in the generated parser.
ParseException()
          The following constructors are for use by you for whatever
purpose you can think of.
ParseException(String message)
           

Method Summary
 StringgetMessage()
          This method has the standard behavior when this object has been
created using the standard constructors.

Field Detail

currentToken

public Token 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.

expectedTokenSequences

public int[][] 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.

tokenImage

public String[] 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 interface.
Constructor Detail

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.

public ParseException(String message)
Method Detail

getMessage

public String 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.
