Method Detail

parseDoubles

private double[] parseDoubles(java.lang.String str,
                              int count)

yy_unpack

private static int[] yy_unpack()
Unpacks the split, compressed DFA transition table.

Returns:
the unpacked transition table

yy_unpack

private static int yy_unpack(java.lang.String packed,
                             int offset,
                             int[] trans)
Unpacks the compressed DFA transition table.

Parameters:
packed - the packed transition table
Returns:
the index of the last entry

yy_advance

private int yy_advance()
                throws java.io.IOException
Gets the next input character.

Returns:
the next character of the input stream, EOF if the end of the stream is reached.
Throws:
IOException - if any I/O-Error occurs

yyclose

public final void yyclose()
                   throws java.io.IOException
Closes the input stream.

java.io.IOException

yyreset

public final void yyreset(java.io.Reader reader)
                   throws java.io.IOException
Closes the current stream, and resets the scanner to read from a new input stream. All internal variables are reset, the old input stream cannot be reused (internal buffer is discarded and lost). Lexical state is set to YY_INITIAL.

Parameters:
reader - the new input stream
java.io.IOException

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.


yy_ScanError

private void yy_ScanError(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

private 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()!

yylex

public int yylex()
          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.

Returns:
the next token
Throws:
IOException - if any I/O-Error occurs
