Constructor Detail

Scanner

public Scanner(Reader in)
Creates a new scanner There is also a java.io.InputStream version of this constructor.
Parameters:
in - the java.io.Reader to read input from.

Scanner

public Scanner(InputStream in)
Creates a new scanner. There is also java.io.Reader version of this constructor.
Parameters:
in - the java.io.Inputstream to read input from.
Method Detail

yyclose

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

yyreset

public final void yyreset(Reader reader)
                   throws 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

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 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.

next_token

public java_cup.runtime.Symbol next_token()
                                   throws 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
