DefaultJavaCommentLexer
public DefaultJavaCommentLexer(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.
-
DefaultJavaCommentLexer
public DefaultJavaCommentLexer(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
-
lex
public int lex() throws java.io.IOException
-
setLineOffset
public void setLineOffset(int lineOffset)
-
setColumnOffset
public void setColumnOffset(int columnOffset)
-
getCodeBody
public java.lang.String getCodeBody()
- Specified by:
getCodeBody
in interfaceLexer
-
yyclose
public final void yyclose() throws java.io.IOException
Closes the input stream.- Throws:
java.io.IOException
-
yyreset
public final void yyreset(java.io.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.
-
yybegin
public final void yybegin(int newState)
Enters a new lexical state- 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.
-
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 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
