public Class ParseException

extends Exception
Class Inheritance
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

Modifier and TypeField and Description
public Token
currentToken

This is the last token that has been consumed successfully.

protected static String
EOL

The end of line string (we do not use System.getProperty("") so that we are compatible with Android/GWT);

public int[][]
expectedTokenSequences

Each entry in this array is an array of integers.

private static final String
INDENT

private static final long
serialVersionUID

Hides java.lang.Exception.serialVersionUID.

The version identifier for this Serializable class.
public String[]
tokenImage

This is a reference to the "tokenImage" array of the generated parser within which the parse error occurred.

Constructor Summary

AccessConstructor and Description
public
ParseException(Token currentTokenVal, int[][] expectedTokenSequencesVal, String[] tokenImageVal)

public
ParseException(Token currentTokenVal, int[][] expectedTokenSequencesVal, String[] tokenImageVal, String lexicalStateName)

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)

Constructor with message.

Method Summary

Modifier and TypeMethod and Description
pack-priv static 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.

private static String
initialise(Token currentToken, int[][] expectedTokenSequences, String[] tokenImage, String lexicalStateName)

It uses "currentToken" and "expectedTokenSequences" to generate a parse error message and returns it.

Field Detail

currentTokenback 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.

EOLback to summary
protected static String EOL

The end of line string (we do not use System.getProperty("") so that we are compatible with Android/GWT);

expectedTokenSequencesback 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.

INDENTback to summary
private static final String INDENT
serialVersionUIDback to summary
private static final long serialVersionUID

Hides java.lang.Exception.serialVersionUID.

The version identifier for this Serializable class. Increment only if the serialized form of the class changes.

tokenImageback 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.

public ParseException(Token currentTokenVal, int[][] expectedTokenSequencesVal, String[] tokenImageVal)
ParseExceptionback to summary
public ParseException(Token currentTokenVal, int[][] expectedTokenSequencesVal, String[] tokenImageVal, String lexicalStateName)

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.

ParseExceptionback 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.

ParseExceptionback to summary
public ParseException(String message)

Constructor with message.

Method Detail

add_escapesback to summary
pack-priv static 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.

initialiseback to summary
private static String initialise(Token currentToken, int[][] expectedTokenSequences, String[] tokenImage, String lexicalStateName)

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) the correct error message gets displayed.
