Constructor Summary

ParseException()
This constructor indicates an internal parser error.

ParseException(java.lang.String message, int line, int column)
The following constructors are for use by you for whatever purpose you can think of.

ParseException(java.lang.String message, int line, int column, java.lang.Throwable cause)

ParseException(java.lang.String message, java.lang.String msgID, java.lang.Object[] args, int line, int column)

ParseException(java.lang.String message, java.lang.String msgID, java.lang.Object[] args, int line, int column, java.lang.Throwable cause)

ParseException(oracle.rules.rl.parse.Token currentToken, int[][] expectedTokenSequences, java.lang.String[] tokenImage)
This constructor is used by the method "generateParseException" in the generated parser.

Method Summary

Field Detail

encountered

public java.lang.String encountered

This is the value of the unexpected token.

public java.lang.String expected

The values of tokens expected at this point of the parse.

expectOne

public boolean expectOne

Whether just one token stream is expected

Constructor Detail

ParseException

public ParseException()

This constructor indicates an internal parser error.

ParseException

public ParseException(oracle.rules.rl.parse.Token currentToken,
                      int[][] expectedTokenSequences,
                      java.lang.String[] tokenImage)

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 "encountered", "expected", and "expectOne" set. This ParseException should never be thrown. It is used to pass the 3 fields to an ExceptionFactory.createParseException() method to localize the error message. This constructor calls its super class with the string "Internal Error localizing error message" just in case it should accidently get thrown.

ParseException

public ParseException(java.lang.String message,
                      int line,
                      int column)

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.
