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.
Static Fields
EOL
protected static String EOL
The end of line string for this machine.

Constructors
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.
ParseException(Token currentTokenVal, int[][] expectedTokenSequencesVal, String[] tokenImageVal)
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.
Name | Description |
currentTokenVal | Token |
expectedTokenSequencesVal | int[][] |
tokenImageVal | String[] |
ParseException(String message)
public ParseException(String message)
Constructor with message.
Name | Description |
message | String |
Fields
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 following this token will (therefore) be the first error token.
Type | Description |
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.
Type | Description |
int[][] |
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.
