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)

yybegin

public final void yybegin(int newState)

Enters a new lexical state

Parameters: newState the new lexical state

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

yyclose

public final void yyclose()

Closes the input stream.

yylength

public final int yylength()

Returns the length of the matched text region.

yylex

public int yylex()

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

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()!

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

yystate

public final int yystate()

Returns the current lexical state.

yytext

public final String yytext()

Returns the text matched by the current regular expression.
