Class ParseException

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.

Constructors

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()

ParseException(Token, Int32[][], String[])

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.

Declaration
public ParseException(Token currentTokenVal, int[][] expectedTokenSequencesVal, string[] tokenImageVal)
Parameters
Type Name Description
Token currentTokenVal
System.Int32[][] expectedTokenSequencesVal
System.String[] tokenImageVal

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.

Declaration
public Token CurrentToken { get; set; }
Property Value
Type Description
Token

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.

Declaration
public int[][] ExpectedTokenSequences { get; set; }
Property Value
Type Description
System.Int32[][]

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.

Declaration
public string[] TokenImage { get; set; }
Property Value
Type Description
System.String[]
