Constructor Detail

JFlexLexer

public JFlexLexer(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.

JFlexLexer

public JFlexLexer(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

setCaptureCodeBody

public void setCaptureCodeBody(boolean shouldCaptureCodeBody)

text

public String text()
Specified by:
text in interface Lexer

lex

public int lex()
        throws IOException
Specified by:
lex in interface Lexer
Throws:
IOException

getLine

public int getLine()
Specified by:
getLine in interface Lexer

getColumn

public int getColumn()
Specified by:
getColumn in interface Lexer

getCodeBody

public String getCodeBody()
Specified by:
getCodeBody in interface Lexer

yyclose

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

Throws:
IOException

yypushStream

public final void yypushStream(Reader reader)
Stores the current input stream on a stack, and reads from a new stream. Lexical state, line, char, and column counting remain untouched. The current input stream can be restored with yypopstream (usually in an <> action).

Parameters:
reader - the new input stream to read from
See Also:
yypopStream()

yypopStream

public final void yypopStream()
                       throws IOException
Closes the current input stream and continues to read from the one on top of the stream stack.

Throws:
EmptyStackException - if there is no further stream to read from.
IOException - if there was an error in closing the stream.
See Also:
yypushStream(java.io.Reader)

yymoreStreams

public final boolean yymoreStreams()
Returns true iff there are still streams left to read from on the stream stack.


yyreset

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.

Parameters:
reader - the new input stream
See Also:
yypushStream(java.io.Reader), yypopStream()

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.


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()!

yylex

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