zzUnpackCMap
private static char[] zzUnpackCMap(java.lang.String packed)
Unpacks the compressed character translation table.- Parameters:
packed
- the packed character translation table- Returns:
- the unpacked character translation table
-
zzRefill
private boolean zzRefill() throws java.io.IOException
Refills the input buffer.- Returns:
false
, iff there was new input.- Throws:
java.io.IOException
- if any I/O-Error occurs
-
yyclose
public final void yyclose() throws java.io.IOException
Closes the input stream.- Throws:
java.io.IOException
-
yyreset
public final void yyreset(java.io.Reader reader)
Resets the scanner to read from a new input stream. Does not close the old reader. All internal variables are reset, the old input stream cannot be reused (internal buffer is discarded and lost). Lexical state is set to ZZ_INITIAL.- Parameters:
reader
- the new input stream
-
yystate
public final int yystate()
Returns the current lexical state.
-
yybegin
public final void yybegin(int newState)
Enters a new lexical state- Parameters:
newState
- the new lexical state
-
yytext
public final java.lang.String yytext()
Returns the text matched by the current regular expression.
-
yycharat
public final char yycharat(int pos)
Returns the character at position pos from the matched text. It is equivalent to yytext().charAt(pos), but faster- Parameters:
pos
- the position of the character to fetch. A value from 0 to yylength()-1.- Returns:
- the character at position pos
-
yylength
public final int yylength()
Returns the length of the matched text region.
-
zzScanError
private void zzScanError(int errorCode)
Reports an error that occured while scanning. In a wellformed scanner (no or only correct usage of yypushback(int) and a match-all fallback rule) this method will only be called with things that "Can't Possibly Happen". If this method is called, something is seriously wrong (e.g. a JFlex bug producing a faulty scanner etc.). Usual syntax/scanner level error handling should be done in error fallback rules.- Parameters:
errorCode
- the code of the errormessage to display
-
yypushback
public void yypushback(int number)
Pushes the specified amount of characters back into the input stream. They will be read again by then next call of the scanning method- Parameters:
number
- the number of characters to be read again. This number must not be greater than yylength()!
-
zzDoEOF
private void zzDoEOF() throws java.io.IOException
Contains user EOF-code, which will be executed exactly once, when the end of file is reached- Throws:
java.io.IOException
-
next_token
public java_cup.runtime.Symbol next_token() throws java.io.IOException
Resumes scanning until the next regular expression is matched, the end of input is encountered or an I/O-Error occurs.- Specified by:
next_token
in interfacejava_cup.runtime.Scanner
- Returns:
- the next token
- Throws:
java.io.IOException
- if any I/O-Error occurs
