Exception ParseException (0.7.0)

publicclass ParseExceptionextendsException

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

protectedstaticStringEOL

The end of line string for this machine.

Type Description

Constructors

ParseException()

publicParseException()

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)

publicParseException(TokencurrentTokenVal,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.

Parameters
Name Description
currentTokenVal Token
expectedTokenSequencesVal int[][]
tokenImageVal String[]

ParseException(String message)

publicParseException(Stringmessage)

Constructor with message.

Parameter
Name Description
message String

Fields

currentToken

publicTokencurrentToken

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.

Field Value
Type Description

expectedTokenSequences

publicint[][]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.

Field Value
Type Description
int[][]

tokenImage

publicString[]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.

Field Value
Type Description
String[]
