Constructor Summary

KjcScanner(Compiler compiler, InputBuffer buffer)

KjcScanner(InputStream in)
Creates a new scanner.

KjcScanner(Reader in)
Creates a new scanner There is also a java.io.InputStream version of this constructor.

Method Summary

InputBufferState	getBufferState() Exports the buffer state.
Token	nextTokenImpl() Resumes scanning until the next regular expression is matched, the end of input is encountered or an I/O-Error occurs.
void	yybegin(int newState) Enters a new lexical state
char	yycharat(int pos) Returns the character at position pos from the matched text.
void	yyclose() Closes the input stream.
int	yylength() Returns the length of the matched text region.
void	yyreset(Reader reader) Closes the current stream, and resets the scanner to read from a new input stream.
int	yystate() Returns the current lexical state.
String	yytext() Returns the text matched by the current regular expression.

Constructor Detail

KjcScanner

public KjcScanner(Compiler compiler,
                  InputBuffer buffer)

KjcScanner

public KjcScanner(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.

KjcScanner

public KjcScanner(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

getBufferState

public InputBufferState getBufferState()

Exports the buffer state.

Specified by:

getBufferState in class Scanner

yyclose

public final void yyclose()
                   throws IOException

Closes the input stream.

Throws:

IOException

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

Throws:

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 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.

nextTokenImpl

public Token nextTokenImpl()
                    throws IOException

Resumes scanning until the next regular expression is matched, the end of input is encountered or an I/O-Error occurs.

Specified by:

nextTokenImpl in class Scanner

Returns:

the next token

Throws:

IOException - if any I/O-Error occurs
