OpenJDK 27 · com.sun.tools.example.debug.expr.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.

Field Summary

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.
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

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	ParseException(String message) Constructor with message.

Method Summary

Modifier and Type	Method 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) It uses "currentToken" and "expectedTokenSequences" to generate a parse error message and returns it.

Field Detail

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 following 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.

serialVersionUID	back 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.

serialVersionUID

back 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.

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.

Constructor Detail

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.

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.
