com.flexive.sqlParser.ParseException
| ParseException | | public class ParseException extends Exception (Code) | | 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.
|
| Field Summary | |
| 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. |
| Constructor Summary | |
| 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 | ParseException(String message)
|
| Method 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. | | public String | getMessage()
This method has the standard behavior when this object has been
created using the standard constructors. |
| currentToken | | public Token currentToken(Code) | | 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 | | protected String eol(Code) | | The end of line string for this machine.
|
| expectedTokenSequences | | public int[][] expectedTokenSequences(Code) | | 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 | | protected boolean specialConstructor(Code) | | This variable determines which constructor was used to create
this object and thereby affects the semantics of the
"getMessage" method (see below).
|
| tokenImage | | public String[] tokenImage(Code) | | 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 | | public ParseException(Token currentTokenVal, int[][] expectedTokenSequencesVal, String[] tokenImageVal)(Code) | | 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 | | public ParseException()(Code) | | 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.
|
| add_escapes | | protected String add_escapes(String str)(Code) | | Used to convert raw characters to their escaped version
when these raw version cannot be used as part of an ASCII
string literal.
|
| getMessage | | public String getMessage()(Code) | | 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.
