main

back to summary

public static void main(String[] argv)

Runs the scanner on input files. This is a standalone scanner, it will print any unmatched text to System.out unchanged.

Parameters

argv:String[]: the command line, contains the filenames to run the scanner on.

value	back to summary
public Object value()

yybegin	back to summary
public final void yybegin(int newState) Enters a new lexical state Parameters newState:int the new lexical state

yybegin

back to summary

public final void yybegin(int newState)

Enters a new lexical state

Parameters

newState:int: the new lexical state

yycharat back to summary

yycharat	back to summary
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:int the position of the character to fetch. A value from 0 to yylength()-1. Returns:char the character at position pos

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:int: the position of the character to fetch. A value from 0 to yylength()-1.

Returns:char

the character at position pos

yyclose	back to summary
public final void yyclose() throws IOException Closes the input stream.

yylength	back to summary
public final int yylength() Returns the length of the matched text region.

yylex

back to summary

public int yylex() throws IOException

Resumes scanning until the next regular expression is matched, the end of input is encountered or an I/O-Error occurs.

Returns:int

the next token

Exceptions

IOException:: if any I/O-Error occurs

yypushback

back to summary

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:int: the number of characters to be read again. This number must not be greater than yylength()!

yyreset back to summary

public final void yyreset(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. Internal scan buffer is resized down to its initial length, if it has grown.

Parameters

reader:Reader: the new input stream

yystate	back to summary
public final int yystate() Returns the current lexical state.

yytext	back to summary
public final String yytext() Returns the text matched by the current regular expression.

zzRefill back to summary

private boolean zzRefill() throws IOException

Refills the input buffer.

Returns:boolean

false, iff there was new input.

Exceptions

IOException:: if any I/O-Error occurs

zzScanError

back to summary

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:int: the code of the errormessage to display

zzUnpackAction	back to summary
private static int[] zzUnpackAction()

zzUnpackAction	back to summary
private static int zzUnpackAction(String packed, int offset, int[] result)

zzUnpackAttribute	back to summary
private static int[] zzUnpackAttribute()

zzUnpackAttribute	back to summary
private static int zzUnpackAttribute(String packed, int offset, int[] result)

zzUnpackCMap

back to summary

private static char[] zzUnpackCMap(String packed)

Unpacks the compressed character translation table.

Parameters

packed:String: the packed character translation table

Returns:char[]

the unpacked character translation table

zzUnpackRowMap	back to summary
private static int[] zzUnpackRowMap()

zzUnpackRowMap	back to summary
private static int zzUnpackRowMap(String packed, int offset, int[] result)

zzUnpackTrans	back to summary
