| Modifier and Type | Field and Description |
|---|---|
| public Token | currentToken
This is the last token that has been consumed successfully. |
| protected String | eol
The end of line string for this machine. |
| public int[][] | expectedTokenSequences
Each entry in this array is an array of integers. |
| protected boolean | specialConstructor
This variable determines which constructor was used to create this object and thereby affects the semantics of the "getMessage" method (see below). |
| public String[] | tokenImage
This is a reference to the "tokenImage" array of the generated parser within which the parse error occurred. |
| Access | Constructor and Description |
|---|---|
| public | ParseException(Token currentTokenVal, int[][] expectedTokenSequencesVal, String[] tokenImageVal)
This constructor is used by the method "generateParseException" in the generated parser. |
| public | ParseException()
The following constructors are for use by you for whatever purpose you can think of. |
| public |
| Modifier and Type | Method and Description |
|---|---|
| protected String | add_escapes(String str)
Used to convert raw characters to their escaped version when these raw version cannot be used as part of an ASCII string literal. |
| public String | getMessage()
Overrides java. This method has the standard behavior when this object has been created using the standard constructors. |
| currentToken | back to summary |
|---|---|
| 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. | |
| eol | back to summary |
|---|---|
| protected String eol The end of line string for this machine. | |
| expectedTokenSequences | back to summary |
|---|---|
| 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. | |
| specialConstructor | back to summary |
|---|---|
| protected boolean specialConstructor This variable determines which constructor was used to create this object and thereby affects the semantics of the "getMessage" method (see below). | |
| tokenImage | back to summary |
|---|---|
| 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. | |
| ParseException | back to summary |
|---|---|
| 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 | back to summary |
|---|---|
| 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 | back to summary |
|---|---|
| public ParseException(String message) | |
| add_escapes | back to summary |
|---|---|
| protected String add_escapes(String str) Used to convert raw characters to their escaped version when these raw version cannot be used as part of an ASCII string literal. | |
| getMessage | back to summary |
|---|---|
| public String getMessage() Overrides java. 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.
