setClientPropertyMap

public void setClientPropertyMap(java.util.Map clientProperties)
Sets the client properties for a querty. Note that the code is not threadsafe. The invoker must ensure threadsafety.


symbol

private java_cup.runtime.Symbol symbol(int type)

symbol

                                       java.lang.Object value)

symbolFromProperty

Helper method to retrieve a particular client property. If the property has not been found in the map, then a NULL_OBJECT symbol is returned. The type of this object is not determined here. It is handled syntactically in the parser.


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 interface java_cup.runtime.Scanner
Returns:
the next token
Throws:
java.io.IOException - if any I/O-Error occurs
