Constructor Detail

PythonFlexScanner

public PythonFlexScanner(java.io.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.

PythonFlexScanner

public PythonFlexScanner(java.io.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

scan

public void scan()
          throws java.io.IOException
Overrides:
scan in class FlexScanner

yyclose

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

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.
Overrides:
yyreset in class FlexScanner
Parameters:
reader - the new input stream

yystate

public final int yystate()
Returns the current lexical state.
Overrides:
yystate in class FlexScanner
Following copied from class: org.skunk.swing.text.syntax.FlexScanner
Returns:
the current state of the scanner.

yybegin

public final void yybegin(int newState)
Enters a new lexical state
Overrides:
yybegin in class FlexScanner
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.

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:
java.io.IOException - if any I/O-Error occurs
